Extractors

Yes, The Gaskets provided will withstand ethanol but are (A-D) as a B for ethanol degradation. The proper gaskets are silicone when ethanol is to be used as the extractant.

No, you cannot. CO2 pressures are far too high for most large diameter fittings on our extractor systems. BVV cannot permit the use of that CO2 with any of our extractors.

Yes, the 20LB Solvent tanks do not have dip tubes. Therefore, you need to flip them upside down to get the liquid solvent out. Beginning in Summer 2020, BVV will sell 20lb tanks with dip tubes.

A single-stage pump has one dual rotor and one set of vanes. However, two-stage pumps have two rotors and two sets of vanes. The first stage generates a medium vacuum and the second stage processes the exhaust of the first stage to create a better vacuum. As a result, two-stage pumps produce a deeper vacuum than single-stage pumps.

The Injection Coil helps prevent any fats and lipids from getting into your extract. The device goes directly in line between the LP refrigerant recovery tank and the material column. This base will be packed with dry ice so the solvent is chilled as it passes through the material column.

The extraction kit comes with all the essentials, and extra gaskets . However, a butane scale, a butane leak detector, and a form of an exhaust (most commonly a fan) is always recommended.

Propane has a lower boiling point, so it evaporates easier but requires colder temperatures to condense. Butane has a higher boiling point, which allows gas to be chilled and move freely throughout the system with little to no help of additional pressure. 

Safety! Closed column extraction or open blasting is hazardous because it allows flammable gas (butane, propane) out into the atmosphere, which creates an opportunity for combustion. 

Consult with your local fire marshal to understand the type of equipment, location, and building preclusions before making a decision. 

Both alcohols are used for extraction, however, 200 proof ethanol is 100% pure. This ethanol is anhydrous, which makes it perfect for effortless purging.

710 solvent is 200 proof ethanol with a small amount of Heptane added to it. This denatures the ethanol and avoids federal excise tax. It also requires special attention post-processing to remove residual heptane.

710 solvent is 200 proof ethanol with a small amount of Heptane added to it. This denatured solvent is perfect for processors who wish to avoid paying excise taxes on ethanol. Ethanol and heptane form an azeotrope, meaning it cannot be separated by simple distillation. The two solvents boil together, so it can be used exactly the same as 200 proof.

**Note: This is a denatured product and should never be consumed directly. Do not use 710 as a diluent in tinctures or other products that are directly consumed without solvent removal.

Generally, 5lbs of solvent are used per lb of material. Please consult your user manual to see your system’s max capacity. Do not overfill the system.

Chill the receiving LP, then connect the source tank to the LP vapor port. Weigh the desired amount of solvent into the LP tank.

Yield is determined by the material used. You can only extract the resin contained in the biomass, so yields will reflect the percentage of resin in your biomass.
