Description
Solvent Recovery Kit - 2 Gallon
The BVV Solvent Recovery Kit makes it easy for anyone to recover and reuse their extraction solvent. The kit uses a vacuum pump to lower the boiling point of the solvent, then will use a cooling source such as ice or dry ice to turn the vaporized solvent back into liquid form. This kit has a few different seals, be sure that all materials are compatible with your solvent. These materials include:
- Viton (FKM)
- Silicone
- EPDM / Butyl
Please verify before using that all these materials are compatible with your solvent. For an easy resistance chart please visit the Cole Parmer link below:

Not included in the kit, you will need:
- Ice Tray
- Ice Bucket
- Ice or dry ice
A 5 gallon bucket and disposable aluminum catering tray will suffice, however a container with a drain plug or valve would be ideal to easily drain the water produced throughout the process.
This kit requires a vacuum pump to operate, we would recommend a chemically resistant diaphragm vacuum pump. We include a 1/4" JIC and 1/4" barb connection to connect to your vacuum pump. The included hosing is 1/4" ID Tygon tubing to easily attach to a barbed vacuum pump.
Running the Unit
Caution: Unit uses flammable solvents. Use caution while operating unit. ALWAYS OPERATE IN EXTREMELY WELL VENTILATED AREAS
- Place your solution into the Evaporating Vessel. This can be done by:
- removing the lid and pouring the solution into the vessel
- Using the vacuum pump to suck the liquid mixture through the Liquid Inlet Port. Using this method, you can use a Micro-Cap filter in-line to remove solid particulate.
- Close the Liquid Inlet Port valve and Air Inlet valve
- Add ice to the bucket and tray. A drain valve built in to the ice bucket and tray would help to drain water later in the test.
- Open the Vacuum Pump valve and turn on the Vacuum Pump
- Turn on the Heat Plate. An induction heating plate is recommended
- Replace ice as needed throughout the run
- When recovery is completed, close the Vacuum Pump valve and turn off the Vacuum Pump.
- Open the Air Inlet valve and release the vacuum pressure from the chamber. Use the included micron filter to prevent contaminants from entering the vessel.
- Turn off the Heat Plate and allow the solute in the Evaporating Vessel to come down to a safe temperature. Removing the solute is easiest when it is still warm.
- Remove the solvent from the Receiving Vessel.
- Once the kit is cooled down, use clean ethanol to wipe down the sealing surfaces for the next run.
