Yes. PurePressure's custom designed, 100% aluminum heat plates qualify for food-grade manufacturing and processing when used with adequate parchment paper, such as our 35lb premium vegetable parchment. 

We machine our plates out of aluminum in-house, as opposed to stainless steel, for better heat distribution. Stainless steel distributes heat unevenly, which can use discrepancies in your rosin when pressing. We do offer stainless steel plates if requested at a small additional fee.

All four of our rosin presses proudly feature our Pressware LCD touchscreen technology, which offers a level of control that no other rosin press on the market even comes close to. PurePressure's Pressware is delivered from our completely custom hardware (no Arduino or Raspberry PI here!) and our fully proprietary software. Here are just some of the things you can do!

Crystal Clear Full Color Touchscreen

PurePressure's LCD touch screens are in a class of their own when it comes to rosin presses. With a beautiful full color display you have more insight than ever before, including at-the-bag pressure readings with pre-set bag sizes. 

Control Every Variable

From temperature and time to multiple pressure stages and more, controlling every aspect of your rosin press is better than ever. You can even change your settings from Imperial to Metric. Tap, save, press. 

Save Up To 30 Recipes

Once you dial in how you want to press your flower, kief, or hash, repeat those results 100% consistently every time. Name, store, and save up to 30 per-determined instructions which can be as simple or as granular with your settings as you can dream of.

Intuitive Menus 

Navigating and using the Pressware system is extremely simple. Everything is right in front of you, so no digging around to find your last run data, quick press, or to load your favorite recipes. Perfecting your pressing process has never been easier.

The Dual Pressure Upgrade Kit is extremely helpful for pressing kief, dry sift, hash, and bubble hash to avoid bag blowouts completely. Our upgrade kit enables you to ramp up from a lower set pressure to a higher pressure, at your command. 

This upgrade kit is highly recommended for anyone who intends to press kief or bubble hash.

When you're squishing hard to press material, such as greasy bubble hash or kief, the amount of rosin oil trying to escape the bag is much higher than when you are pressing flower, trim, or shake. If you apply too much force too quickly, it can rip your bag open and you have to start over. With the Dual Pressure Upgrade Kit, you never have to worry about that again. By starting your press at a very low pressure, you can let the heat liquefy the oil properly and start escaping, and then increase the pressure slowly to ensure you get the maximum yield.

The Dual Pressure upgrade works by allowing you to start at one set pressure, and then ramp up to a second set pressure with the toggle switch. This is especially helpful when making rosin with hard to press material, such as kief, dry sift, hash, and bubble hash.

There are three positions the toggle switch operates in: left, middle, and right. The left orientation always will use the left regulator's pressure, the middle orientation is neutral and will hold whatever pressure you have set, and the right orientation will increase pressure with the right regulator up to the maximum it is set at.

Start by setting your desired pressures on both regulators, with your starting (lower) pressure on the left regulator, and your maximum (higher) pressure on the right regulator. 

Before pressing, ensure that the toggle switch is set to the left so that it starts at your initial pressure.

Once you've engaged your rosin press, the LCD will readout your initial pressure. To increase pressure, change the toggle from the left position to the right position, which will increase your pressure to the desired amount. 

• CFM: 1.7 or greater
• Tank size: 30 gallons or more recommended, 10 gallons minimum
• PSI: 130 or greater

• CFM: 2.2 or greater
• Tank size: 30 gallons or more recommended, 10 gallons minimum
• PSI: 150 or greater

Yields range significantly and depends largely on the quality of the materials used. Great material in = terrific rosin.

Trim: 3% - 8%

Shake: 8% - 15%

Flower: 15% - 30%

Kief / Dry Sift: 30% - 60%+

Bubble Hash / Hash: 30% - 70%+

Note: Adequate application of pressure is important to achieve optimal yields and these figures are based on averages we have tested using properly packed rosin bags. Results may vary and depend heavily on your material as well as the skill of the rosin press operator.

Currently we are in the process of obtaining official UL certification for our rosin presses.

Every electrical component in our press is UL listed however, so rest assured that we've carefully selected every component to be as safe and functional as possible.

Fire department officials we have spoken with in a number of states have told us that UL certification is not currently a requirement for rosin press use, but we are working to get ahead of the curve on this important issue. If you think this might be a concern, we recommend checking with your local regulators to get a clear answer.

All four of the rosin presses we manufacture do not require any regular cleaning. As long as you are pressing your rosin between high quality parchment paper, such as our 35lb Ultra Bake premium parchment, your heat plates will remain clean.

If you do end up accidentally getting some rosin on the press itself or just want to remove any fingerprints, simply use some rubbing alcohol or a similar denatured alcohol product with a rag or paper towel.

No, an infrared heat gun will not give you an accurate temperature reading. Even extremely expensive ones do not have the ability to accurately read temperatures on reflective surfaces.

PurePressure's Pikes Peak rosin press utilizes two separate heat plate assemblies, each with two heating rods and a thermocouple. For this reason, we're extremely confident in the accuracy of the temperature readings as well as the heat output. The thermocouples require no calibration and we verify that they are within spec long before we they are installed in our presses. The discrepancy in temperature when using a heat or temperature reading gun actually comes from how the infrared thermometers operate. The reflectivity of a surface has a dramatic effect on the temperature reading when using infrared and a shiny surface (like our heat plates) is the worst case scenario. Ideally you need to have a matte black surface for an accurate reading. The only way to accurately spot check the temperature would be with another thermocouple, thermal paste (to ensure good thermal transfer), and a controller to amplify and filter the thermocouple signal.

PurePressure's rosin presses are made with truly premium components and are engineered to press rosin for many years.

General Warranty Terms

Simply put, the cost of our rosin press is directly a reflection of the craftsmanship and quality of its components. With us, you're making an investment for the future - not just a purchase that won't go the distance. You truly get what you pay for with us at PurePressure, and that means a professionally-engineered piece of cannabis extraction equipment with an incredible team to support you. Check out our Why Our Press page to learn more about the incredible technology we've put in our equipment.

Many of our competitor's presses are made in China with low quality components and weren't even manufactured specifically for rosin in the first place. If you're curious, take a peek on Alibaba.com to see how few of the rosin presses you may have seen are actually assembled in the USA!

Finally, the original prototype pre-production Pikes Peak rosin press is still the one we use today for demos and at our shop, which is a testament to its durability. Come see it for yourself and contact us today to set up a live demo at our warehouse in Denver, Colorado!

Yes, unlike Brute trash cans or other non-food grade plastic vessels, the Bruteless series is made from 100% durable, sanitary stainless steel. This ensures that no micro-plastics are left behind in the wash process, due to the vessel you are using.

We have 4 different sizes of Bruteless vessels. The maximum suggested capacity per wash for each vessel size is listed below:

20 gallon - 2,500 fresh frozen grams or 500 dry grams

30 gallon - 5,000 fresh frozen grams or 1,000 dry grams

44 gallon - 10,000 fresh frozen grams or 2,000 dry grams

65 gallon - 15,000 fresh frozen grams or 5,000 dry grams

We strongly recommend deep cleaning your Bruteless stainless steel vessel, fittings, and paddle at the end of each day’s washing. This will help ensure that your system stays contaminant free, which is crucial. RO water can be extremely corrosive; surface rust can appear even on stainless steel because of rogue particulate in standing water on the metal. We have two different cleaning recommendations depending on if you are cleaning your lines or the stainless steel surfaces of your system.

The Bruteless insulation jacket is composed of a shell and a core. The shell is neoprene and can be wiped clean with isopropyl alcohol if needed. The core is a moisture resistant closed cell foam and should not absorb liquid.

PurePressure's Axis trichome separator is our take on an automated hash washing machine. It offers unparalleled control, machine utilization, and scalability for solventless processors. The unique design separates the washing vessels from the source of agitation, which enables extractors to wash in one vessel while the next one is being filled, pre-soaked, or filtered. This creates massive efficiencies both in terms of batch processing throughput and labor cost savings.

Built in the USA, the Axis' wash down rated stainless steel housing allows for easy cleaning and sanitation. It also features a joystick that's coupled with a touch screen control panel to mimic hand-paddle agitation. Begin washing like a pro from the start with preset and custom recipes, further increasing your ability to produce challenging SKUs like full melt or six star hash with ease and consistency.

The Axis trichome separator works with the 30, 44, and 65 gallon Bruteless vessels. Depending on the size of your vessel you can wash, filter, and collect up to 132 lb (60,000 grams) or more of fresh frozen material per 9 hour shift.

Listed below are the capacities of fresh frozen flower (grams) that the Axis can wash with each size of Bruteless vessel at one time:

30 gallon - 5,000 grams per batch

44 gallon - 10,000 grams per batch

65 gallon - 15,000 grams per batch

The Axis trichome separator's compressed air requirements are: 100 PSI, < 1 CFM.

For more information, see the full user manual here.

Typically, full melt hash contains trichomes that fall in the range of 90µm-120µm, but each strain and even each plant is different. The full micron spectrum range for most hash washing filter bag sets ranges from 25µm-220µm. Full melt is also achievable in some instances with very high quality dry sift, but is less common than with ice water hash.

PurePressure's Pneumatic Hash Pump is a stainless steel fluid management system that eliminates gravity draining and feeding during hash washing. It is perfect for connecting multiple/separate wash systems together in your lab.

This hash-safe pump has a gentle, low shear flow that protects delicate trichomes from being damaged. It includes an integrated control stand that allows the operator to adjust pressure and speed of the pump on the fly.

The compressed air requirements of the Pneumatic Hash Pump are listed below:

Max inlet pressure to pump: 104 PSI

Max inlet pressure to included regulator: 150 PSI

Compressor should produce 5 CFM at 40 PSI minimum

Air consumption could be as low as 5 CFM at 20 PSI

Air consumption could be as high as 20 CFM at 104 PSI

Typically you will always want to press using a rosin bag for a couple reasons, namely that they provide crucial filtration in order to achieve the highest quality rosin possible. With kief and hash rosin specifically, there is virtually no other way to do it since due to the granularity of those starting materials, simply pressing them without a bag will result in a mess of liquefied trichome heads and organic detritus.

Yes, absolutely. We sell rosin bags in multiple sizes and micron mesh variants to ensure that our bags are usable in all set ups. All bags we sell are sewn in Denver, Colorado with premium grade 100% polyester monofilament and are color coded for ease of micron recognition.

For example, if you're using a hair straightener, we recommend purchasing the 2" x 3" bags for ease of use. For any other heated rosin press, select the bag that closest resembles your heat plate size. We sell the following sizes:

2" x 3"

2" x 6"

2" x 9"

2.5" x 4.5"

2.5" x 9"

Typically you can fit more kief, dry sift, or ice water hash gram for gram into a rosin bag than flower, trim, or shake. This is because those materials are more dense and weigh more by volume.

See the full collection here.

Yes, we do!

If you're interested in rosin bags in a custom size, please contact us and we will get you a quote. Please note: this option is only available for bulk orders exceeding 5,000 units.

The Pharmaceutical Harvest Right models can be used for food purposes. However, we recommend purchasing the Home freeze dryer shelving insert if you are using your Pharmaceutical model to freeze dry food. If you would like to purchase this, contact us. Making some freeze dried bananas or other goodies between hash batches is always fun!

Since we do not manufacture Harvest Right freeze dryers, we suggest that you contact Harvest Right directly to be best assisted with your support needs. If you purchased your Harvest Right freeze dryer from us, we'd be happy to go to bat for you with Harvest Right since they sometimes are not the fastest to respond. If you didn't purchase your freeze dryer from us, unfortunately we do not offer direct end user support.

Yes. If you see a better price on a Harvest Right freeze dryer, we will gladly match and beat it. Contact us for a price match today.

We typically see freeze dryers run between 45°F and 55°F to best preserve the terpenes, but shelf temperatures will affect your drying times considerably. For more freeze drying tips and tricks, read this article. We also sell SOPs for Harvest Right and Labconco freeze dryers if you really want to perfect your drying cycles.

The shelf life of rosin is similar to BHO or other concentrates in that it will last a very long time on the shelf if kept in properly sealed containers. 

Your rosin's consistency depends entirely on how it's produced and stored, however rosin generally tends to automatically develop a budder-like texture if left out at room temperature. You can refrigerate your rosin like any other extract product to prolong its shelf life and preserve its original consistency for longer periods of time.

The following 3 factors heavily influence the color or clarity of your rosin:

1. Quality of your material
2. Age of your material
3. Temperature at which your material is pressed at

To get the best, brightest rosin, we recommend pressing your flower, kief, or bubble hash as soon as possible after it has been dried, cured, and processed from the original harvest. Quality in = quality out, and pressing too hot (typically above 250 degrees Fahrenheit) may darken your rosin as well as potentially harm the terpene profile, especially with flower rosin. Bubble hash and kief seem to be somewhat more heat resistant when pressing rosin in our experience, however.

Generally, the higher the quality of your input pressing material, the better the clarity will be, and vice versa. Same goes for age, which is another critical factor - old material tends to come out darker, although that doesn't necessarily equate to a poorer quality product.

Yes, rosin can mold, though it is not common and you don't hear about it very often. This usually won't happen unless rosin is produced poorly or not tested for contaminants, microbials, etc.

No. Rosin is completely solvent-less and contains no residual compounds such as butane, propane, CO2, or ethanol. Rosin and hash are two of the only truly non-solvent cannabis concentrates available!

Rosin and BHO (butane hash oil) are both cannabis concentrates, but are extracted differently. Both rosin and BHO offer comparable potencies that can range from 60-80%+ in active cannabinoids. Rosin can be manipulated into popular consistencies, such as shatter, budder, wax, sugar, and so on, contrary to popular belief that shatter is only BHO.

Rosin is the result of an extraction method that squeezes cannabinoids (THC, CBD, and their sub variants) out of cannabis material using only heat and pressure, making it solventless.

BHO on the other hand is extracted by using butane, a harsh solvent, which strips cannabinoids from the cannabis material. The resulting oil requires extensive purging in vacuum oven chambers to remove the butane so that it is consumable

Rosin and BHO both have equally comparable THC percentages and potency. 

The amount of active cannabinoids in rosin or BHO mainly depends on how high quality the starting material was. Typically, this percentage range for concentrates is 60% - 90%, whereas cannabis flower by itself tests anywhere from 10% to 30% or slightly over at the most.

In the world of cannabis concentrates, a term you may hear often is "full melt" or "six-star" hash. When talking about ice water hash or "bubble hash" specifically, this is a reference to the quality of the product. Full melt means that the products entirely melts on your banger with little to no residue or debris left after.

When properly stored, fresh frozen cannabis can last in the freezer for up to a year or more.

No. If you are pressing flower, it must be freshly dried and cured. If you attempt to press fresh frozen cannabis it will sizzle and ruin the fresh frozen material. There is far too much water in fresh frozen cannabis to apply direct heat and pressure.

Washing fresh frozen cannabis with ice water, shears off the trichomes via turbulence and agitation. When the plant material is frozen, it creates a more brittle surface that can snap off much easier than if it was not frozen.

Test washing is sometimes done in a sealable glass jar with about 12-24 grams of fresh frozen flower, ice, and water. These jar sized batches are typically not dried and processed, therefore you won't get a weight or any numbers from this. However, this works great as a visual testing method for comparing strains side by side. More experienced processors will use this method because they know what to look for.

For beginners looking to see how their starting flower will yield, your best bet is to wash at least a few hundred grams in a bigger vessel. Eric Simpson (Instagram: @simpsonsolventless) recommends washing 1,000 grams (fresh frozen weight) in a 20 or 32 gallon vessel. This way you will be able to collect the hash, weigh it, and gather proper data from your test wash to further calculate yields on your starting material.

The lower the temperature in your wash room, the better. An ideal wash/ extraction room will be around 60°F or lower. Hash is much easier to work with when it is kept cold, when it is heated it becomes tacky and starts to stick to everything it touches.

Yes. Reverse osmosis water is necessary in the hash washing process. RO water is filtered and stripped of all minerals, microbes, and potential contaminants. This is extremely important as non-RO water such as tap water will leave minerals (or other microscopic elements) behind in your hash after the freeze drying process.

Ice water hash can be stored in an air tight container or glass jar in the freezer for months. It is important to keep the ice water hash cold and preserved so it doesn't begin to lose terpenes and "grease up" before it is time to consume it or press it into rosin.
