The Persei is a flexible portable vaporizer designed to vaporizers both dry herbs and various preparations of concentrates. The device uses rechargeable Lithium Ion batteries to provide either 3.7 (Standard Voltage) or 7.4 (High Voltage)

The Persei is a very portable vaporizer designed for the vaporization of concentrates like BHO, earwax, budder, super melt, etc. Its a battery powered deviced that uses re-chargable lithion ion batteries for power. Originally there was just the Omicron and then came the Persei. The Persei unlike the original omicron includes the flexibility to use industry standard batteries in different configurations for a variety of usages. The Persei currently supports output Voltage of 3.7V, 6.0V, & 7.4V. All of the dealers listed below should have current models available.

Cartridges Overview

All the THC Scientific vaporizers use the same 601 cartridge threading but there are some different ohm cartridges available. Currently there are 1.4, 2.4, 3.0, 4.0, 5.0 ohm cartridges available. How do I know which ones to use?

In simple terms the size of the hit delivered to the user is limited by how much power can be delivered for vaporization. The more power available then the bigger the amount of concentrate that can be vaporized. That said there are realistic limitations to the batteries, switches, and cartridges that create some incompatibilities. More Power is not necessarily better. When you increase power you decrease battery life and accelerate the usage of the concentrate. The original omicron used a 2.4 ohm cartridge. This cartridge will typically provided over 100 hits on a single battery charge.

Understanding how much power each cartridge configuration will produce will help the user select the proper cartridge for their desired dosage. In addition to dosage the viscosity of a concentrate can also effect ones choice in cartridge power. For Example: Pure Gold is a very thin concentrate and can produce very large hits on the 5.0 ohm cartridge where as other concentrates (earwax) might require a 4.0 ohm cart to deliver the same dosage.

Power Formula

Power in Watts = Voltage * Voltage / Resistance.

Plugging the in number of 3.7V for voltage and resistance of 2.4 ohms gives us

5.75 Watts' for a typical Omicron V1 setup.

compared to a single 4 ohm cartridge at 7.4v in a Persei gives us

13.7 watts for a typical Persei setup.

The Persei is can work with a variety of cartridges at each voltage level but not all carridges are compatible with all voltage levels. See the cartridge compatibility section below and the cartridge compatibility matrix for help in selecting the right cartridge for your application.

Compatible Cartridges

The Persei is capable of operating at 3.7, 6, and 7.2 volts depending on the battery(ies). Using a cartridge outside the range for your voltage can cause damage. Comparing the number of watts will be more accurate than comparing the ohms or amps through a cartridge; more watts indicates a hotter cartridge:


  • 1.5 ohm, 2.5 amps --- 9.25 watts
  • 2.4 ohm, 1.5 amps --- 5.75 watts
  • 3 ohm 1.25 amps ----- 4.5 watts


  • 1.5 ohm, 4 amps ----- 24 watts
  • 2.4 ohm, 2.5 amps -- 15 watts
  • 3 ohm, 2 amps -------- 12 watts
  • 4 ohm, 1.5 amps ----- 9 watts
  • 5 ohm, 1.2 amps ----- 7.2 watts


  • 1.5 ohm*, 4.9 amp --- 36.3 watts*
  • 2.4 ohm, 3 amps ----- 22.2 watts
  • 3 ohm, 2.5 amps ----- 18.5 watts
  • 4 ohm, 1.85 amps --- 13.7 watts
  • 5 ohm, 1.5 amps ----- 11.1 watts

* Not recommended, only theoretically safe if battery voltage measures 7.4 volts or less.

On 3.7v, the 1.5 ohm will be hot and powerful so they must be primed carefully. 2.4 ohm are very user-friendly and 3.0 ohm will give very light, flavorful hits. As you can see, at 6v and 7.4v, the cartridges are at least as powerful as the 1.5's on 3.7v so use caution.

The Persei first shipped with 4 ohm cartridges but some of the newer Persei have shipped with 5 ohm cartridges which aren't as likely to burn out if dry fired under full battery voltage (8.4v). All newer cartidges are marked with their ohm value, a 2.4 ohm cartridge would read: "2.4 EC/6 W9 TECH"

The THC Scientific Persei vaporizer is scheduled to be released to the general market on Feb 1st 2012.


The Persei is a lightweight, small hand-held, portable vaporizer designed for vaporizing extracts. The heater is wire, powered by an internal Li-Ion battery pack. The air path is separate from the battery. A Picture of the unit and accessories is below

The entire unit including the battery, the heat shield and the cartridge are made of stainless steel. The Persei/Omicron cartridge is designed to hold up to 1.0g of concentrate. A typical charge will give the user several hundred metered doses on a single charge. The manufacturer claims 400 metered doses off of a single gram of extract.

The cartridge is made of stainless steel, ceramic, wire, rubber seals, and silica rope according to the manufacturer. It is a two chamber system. The first chamber makes the concentrate liquid enough for the wick to soak it up and the second chamber is the vaporization chamber. This design is brand new but will be evolving with more cartridge designs and attachment options.

Power Source

Currently the Persei vaporizer is a variable voltage vaporizer, it can take 18650 3.7v, 2x rcr123 for 6.0 volts, and 2x18350 for total of 7.4v.

18650 will provide over 200+ puffs before it needs to be recharged.

18350 will provide over 100+

There is no battery level indicator other than the button will stop illuminating blue when the button is depressed once the battery has drained.

Li-Ion batteries do not have a memory, but each charging cycle depletes the useful capacity somewhat. This deterioration is unavoidable and permanent, and is accentuated in high-demand applications. The battery pack will therefore need replacement at some point. Because the pattern of use and re-charging determines the battery lifetime, it is not possible to predict how long it will last, but similar battery packs typically last up to three years with proper care.

Prolonging the battery life

Li-Ion batteries will last longer if you do not discharge them completely. A common recommendation for longest battery life is to re-charge when they are discharged to 80% capacity. The best approach is therefore to re-charge between sessions.

Filling Cartridges

Its important to start with understanding What types of concentrates can be used with the omicron so you don't ruin cartridges by filling them with concentrates that will clog and ruin them.

NOTE: Its recommended to not load less than 0.5G or more than 1.0G in a cartridge. Please don't load 0.2g and wonder why its not working well. some users have reported loading more than 1.0g but 1.0g is the manufacturer's recommended maximum.

Some users like to load 0.5g at first and then load another 0.5g later. There is no issue with this approach.

There is now a an official filling tool available and shipped with the unit from THC Scientifc. Originally there was the technique using a glass eye dropper but this technique has been largely replaced as FC member Daelic came up with a much better method you will commonly seen called the Daelic method or the funnel method. This funnel method inspired the official filling tool and both work well.

Checking Cartridge before Filling

One important thing to mention regardless of how you fill the cartridge is to the test the cartridge prior to filling. Attach the cartridge to the battery and depress the button. While depressing the button look down the center air hole. The heating element should be glowing red and the base of the cartridge should start getting warm. If the heating element is not working then the cartridge is DOA and should not be filled. This simple check can save from the end user from having to drain precious concentrate out after filling. This rare but it has happened so test your cartridges before filling.

Pre-Oxidizing Cartridges

If you draw on the cartridge while dry you wont get the most pleasent odor or taste. It taste somewhat like machine oil. Its likely manufacturing residue and the ni-chrome heater wire oxiding. This smell and flavor typically dissipates quickly once the cartridge is loaded. THC scientific is evolving their cartridge manufacturing process to include some extra wash steps and a step to pre-oxidize the heating element. A user at home can also pre-oxidize the heater with the following procedure.

  • Press Button for 3 seconds with dry cartridge.
  • Allow to cool down for 20 seconds
  • Repeat process 5-10 times

If you continue to have flavor issues or concerns please open a ticket with THC Scientific.

Miscellaneous Filling Tips and Tricks

Additionally please dont use the white cap provided except for storage. Using the unit with the white cap on will result in leaks and clogs. Many users completely discard the white caps and never use them at all. Most all concentrates except for Pure Gold seem to be solid at room temperature making the cap redundant in many cases. With a thinner concentrate like PureGold or when storing the unit in a hot environment the white storage cap may be desirable to prevent the concentrate from melting and leaking out the unit.

Additionally some people like to stuff (room temp) earwax down into the cart using a manual process instead of using heat.

Also Pure Gold generally doesn't require a funnel at all. just cut the tip and squeeze the contents of the capsule down into the Cartridge. Use a toothpick or short nail(3/4 x 18 steel nail) in the center air hole to avoid clogging it with the liquid concentrate. The toothpick is effective but the nail fits perfectly.

Priming & unclogging cartridges

Priming after filling

Depress button and draw repeatedly until vapor production begins. The number of button presses required to prime a cartridge will vary greatly based on the viscosity of the concentrate and how well the concentrate flowed down into the cartridge during filling and how/if the cartridge was heated after filling to allow the contents to settle.

Prime all cartridges after filling at 3.7V to avoid damage.

Once vapor production has started (the cart is primed) you can switch back to 6.0 or 7.4v configuration.

Guidelines on priming difficulty for generic concentrates
  • BHO and Hash Oils - These prime fairly easily despite being very viscous.
  • Butane Extracts (aka. Earwax, Super Melt, Budder, etc) - These generally prime very easily with only a few button presses.
  • CO2 (aka. Earwax, Super Melt, Budder, etc) - These generally prime with a little more heat than regular BHO or earwax.
  • 02 Extracts - Limited feedback here but these seem to be more difficult to prime.
  • Shatter Glass - often very difficult to prime. might take a while.
  • ISO Extracts - variable. some users with bad luck and some with great success.
  • Full Melt - DONT USE - Will Clog Cartridge
  • Bubble Hash - DONT USE - WONT MELT
Priming difficulty level for specific extracts common in CA collectives:
  • Liquid N Extracts (aka. Nitro OG Wax) - primes very easily with only a few button presses
  • PureGold - primes very easily with only a few button presses

Priming after clog (aka. clearing a clog)

Its fairly common with the Persei to get a small obstruction in the airway after storage. These small clogs sometimes called pop clogs are easy to clear. It seems the frequency of these clogs depends on many factors such as the viscosity of the extract, the level of fullness of the cart, The position in which the unit was stored and also the temperature at which the unit was stored.

To clear a pop clog simply press the button and hold for 6 seconds while drawing on the Persei very very gently. Release and repeat up to 10 times until unclogged. The pressing of the button will engage the heater and liquify the clog after a few presses typically and then the gentle draw will clear it. you will often hear and feel the small pop when the clog clears. This is all fairly common and normal. If after 10 tries you don't succeed at clearing the clog, remove the cartridge and gently insert a Vito Tool,paper clip, or needle dipped in ISO alcohol into the bottom of the unit very gently until it hits resistance. Push gently and don't push past the resistance (~1cm in). Repeat process with ISO needle on top of cartridge. Insert until it hits the heating element (much farther down than from the bottom) Then re-assemble unit and repeat priming procedure until cleared.

Priming Tips

  • Fuller carts seem to develop this issue more often than emptier carts (gravity? I think so)
  • Store the Persei standing uptight if at all possible.
  • Storing the Persei on its side (laying down) especially after heavy usage can facilitate one of these clogs
  • Storing the Persei in a hot environment on in direct sunlight can facilitate one of these clogs

Priming DONTs

  • Heat the lower part of the cartridge.
  • Overheat the upper part of the cartridge. (Hold it with your hands to gauge heat)
  • Blow into the cartridge.
  • Suck too hard.


The Persei heats up immediately when the button is depressed. When depressed the button should be illuminated blue. This indicates the device is on. When you release the button the device turns off. Unlike the Omicron V1 and O-PHOS there is no 7 second timer to cut the power off. With the Persei you need to excercise caution in applying power. With the 3.7v configurations its possible to hold the button continuously for larger hits. This technique is not advised at higher voltages. Especially with the higher power configurations its very important to modulate the power on and off to the device to A. avoid burning the unit up and B. preserve flavor of the concentrate.

Its very easy to tell when you have applied to much heat with the Persei as the flavor will changed to metallicly flavor. start out slow and learn the button modulation technique that works for your concentrate and configuration.

1. Hold the device to your mouth and inhale gently (like sipping hot coffee through a straw) while holding the button for 2-3 seconds. release button for 2 seconds and repeat until you got a big enough hit.

Additional Techniques (old stuff from Omicron):

  • Flute method. 4 seconds on 2 seconds off, for the duration of the hit.
  • Deep pull, 6 seconds on 2 seconds off, repeat for the duration of the desired lung capacity.
  • Short method, 6 seconds and sit it down

As this wiki entry was being written an excellent user's manual became available from Planet Vape (Canadian Dealer). It has some great flow charts explaining many concepts and functions.

Can I tell how much charge is left in the battery?

No, but some information can be deduced.

  • If the button doesn't illuminate at all then the battery is totally dead.
  • If the button flashes when pressed its low and needs charge.
  • If the button illuminates blue steadily the battery has adequate charge and should be functioning properly.

When should I charge my unit

According to the manufacturer: When its dead.

Can I charge my unit if its not dead without damaging it?


Is there a compact carrying case for a Persei?

There are good solutions for omicron but so far no case is available and no users have posted their home made solutions.

Whats the best way to store the Persei?

Standing up is the best way. This keeps the concentrate toward the bottom of the cartridge where it can be effectively used. A coffee cup can serve as a great holder.

Does the provided charger work with 110v/220v/240v?


Can I charge the Persei with my computer?


Can I use the Persei when the battery is dead

Sure, if you have more than 1 battery simply swap batteries and charge the other. Otherwise no. There is currently no inline charger or pass through system for the Persei.

The fill tool is stuck on my cartridge! How do I remove it?

Screw the cartridge on to the battery, and gently twist the fill tool off. Generally the tool will fit better after using it a few times.

How do I test if a cartridge is working properly?

  • If the cartridge is empty or no multimeter is available then: Attach the cartridge to the battery and depress the button. While depressing the button look down the center air hole. The heating element should be glowing red and the base of the cartridge should start getting warm. If the heating element is not working then the cartridge is not functioning correctly.
  • Using a multimeter measure the resistance of the cartridge from the bottom center to the outside of the cartridge. If the cartridge is functioning correctly you should get a reading of 2.3-2.4 Ohms. A an improperly functioning cartridge will read 5.4 ohms (if one of the 2 heaters in parallel has burned out) or infinite resistance (open circuit) when both heater coils have burned out. The above example is for a 2.4 ohm catridge but scales appropriately for other impedance cartridges.
  • THC Scientific has indicated in the future they will release a simple cartridge testing tool.

I press the battery button and it immediately flashes?

Your battery is low and needs to be charged.

If the problem continues after charging please open a ticket with THC Scientific.

I press the battery button and it does not light up

Please charge the battery and if the batter does not function properly after charging please open a ticket with THC Scientific

Are the cartridges refillable?

The manufacturer recommends a single usage to minimize risk of a cartridge going bad and losing concentrates. Eventually the heater coil will deal and the seals may degrade to the point where the cartridge is not functioning optimally.

Many users have been refilling cartridges with success multiple times. If you as the user are going to exceed the manufactures recommendation and refill cartridges be prepared for the fact that they will die eventually and you will have to throw away some concentrate or try to reclaim from the expired cartridge.

How do you test that a cartridge is working before I fill it?

One important thing to mention regardless of how you fill the cartridge is to the test the cartridge prior to filling. Attach the cartridge to the battery and depress the button. While depressing the button look down the center air hole. The heating element should be glowing red and the base of the cartridge should start getting warm. If the heating element is not working then the cartridge is DOA and should not be filled. This simple check can save from the end user from having to drain precious concentrate out after filling. This rare but it has happened so test your cartridges before filling.

How long does the battery last?

Typically close to two hundred button presses between chargings. for more information see the section on the power source.

How long does a cartridge last?

Manufacturer Claims 400+ metered doses out of single gram of concentrate on 2.4ohm catridge at 3.7v

Users are experiencing similar if not better results in most cases. Some thinner concentrates such Pure Gold may not last nearly as long.

What types of concentrates can I use in this cartridge?

The Persei can vaporize many types of concentrates but they need to have 2 properties.

  • Concentrate must fully melt
  • Concentrate must NOT contain any residual plant matter.

This means hash oils, earwax, budder, supermelt, PureGold, NitroOG, O2 extracts all work fine.

This means any cold water/ice/bubble hash will NOT WORK! (Violates Rule #1)

This means any kief will NOT WORK!! (Violates Rule #1)

This also means any "Full Melt" hash will NOT WORK. (Violates Rule #2)

Shatter Glass works for some and not for others. Its generally very hard to liquify and prime.

ISO extracts seem to have varying success with some users have trouble and others having great success.

Users have reported that California's Harborside club "Taffy" generally does not work.

Its also been reported that "Gold Flake" seen at a number of clubs in/around San Jose, CA seems to vary widely and is generally difficult to prime.

The rule of thumb with extracts is that the lighter the color the better. The darker colors are generally assumed to be caused by plant matter and other impurities. If you live in California then look for products tested butane free by SteepHill Labs or reputable testing facilities. Tetra Labs PureGold is generally considered the highest grade (purest) extract available in California and the only extract known to have the paraffins removed (aka. its de-waxed)

How do I extract concentrate from a dead cartridge?

You need 4 things to reclaim concentrate from a dead cartridge

  • Any small or desktop vice or something like this [sold at Harbor Freight for less than $4]
  • Dish,plate, or something to collect the reclaim on. Something flat and ceramic or glass is good. you want something hard and flat so scraping the reclaim up is not too difficult.
  • Heat source - small torch or barbeque lighter will work better than a standard lighter. because you will generally be using some additional heat a traditional lighter will get hot and its very easy to get burned. using a small torch or barbeque lighter keeps fingers from getting burned.

Example: Benzomatic micro torch from Home Depot

  • Single edge razor - to scrape up the reclaim when your done

Once you have the cartridge positioned. Heat it gently and the concentrate will flow out onto your collection dish. Let the concentrate cool and scrape up with a single edge razor and your done.

Additionally Vitolo came up with this technique to reclaim even more

I am not getting vapor from my cartridge! What do I do?

It always helps to:

  • Check that your battery is not dead (First few times I wasn't getting vapor it was because battery was dieing)
  • Check the cartridge heating element is working before filling. Typically an empty cart is ~7.9 grams with some variance.
  • Weigh the cartridge before you fill it so you know if its really empty or not

If the cartridge has concentrate in it and still appears to be getting hot but little to no visible vapor is coming out chances are the concentrate is stuck to the walls of the cartridge. This is easily remedied by holding the cartridge by the bottom near the threads and then gently heating the top 1/4th of the cartridge allowing the concentrate to settle in. Don't be worried if you get a little smoke, this generally indicates you applied a bit too much heat to one spot.

Again your only heating the top part of the cartridge never the bottom. You will notice the bottom part you are holding wont get warm.

In fact this technique applies less heat to the cartridge than general usage. Users can easily take the heat shield off after 10 button presses and see the cartridge bottom gets hotter during normal usage than during a gentle heating so there should be no adverse effects on the seals in the cartridge.

some users also report wrapping a wet cloth around the bottom (threaded side) and heating the top 1/4 while rolling gently between your fingers.

Additionally and especially if you didn't weigh the cartridge so you don't know if it has concentrate left in it. Use Vitolo's needle tool and heat the needle hot and scrape in along the inside walls of your cartridge. Of course being careful not to press to far down and being gentle. This technique can also help with getting stuck concentrate to settle down in the cartridge.

Whats the best way to stabilize a cartridge for filling?

There are a number of techniques to stabilize a cartridge.

  • place the cartridge in the battery
  • place the cartridge in a small desktop vice
  • drill a hole in a small block of wood and insert the cartridge into the hole. [Pics here]

Can I mix more than one type of concentrate at a time in the Persei?

Numerous forum users have indicated mixing concentrates has no known issues.

Are there any other tools or accessories to enhance its use?

There have been a number of official and user created enhancements for the Persei here

How do I remove the Persei logo from the battery?

Pure Gold Tips and Tricks

  • Here's some tips for dealing with the liquid nature of pure gold.
  • Try loading only 1/2 g at a time. putting a full g in seems to cause more leaks.
  • As THC Scientific said with Pure Gold: Let it cool down for 3 minutes after 2 x 7 second presses. you don't want to get it to hot.
  • After your done pressing the button inhale slowly and help it cool down. If you can remember hit again and 30/60 seconds and clear any pop clog building. This helps insure its clear next you want to use.
  • Don't use the white cap.
  • One user also tested with pure gold carrying the cart attached or detcached in my pocket outdoors doing physical activities. Attached 4 Sure!!!! That way if it does leak it contains the leak versus having it leak MORE in your pocket.
