Liquid–liquid extraction also known as solvent extraction and partitioning, is a method to separate compounds based on their relative solubility’s in two different immiscible liquids, usually water and an organic solvent. It is an extraction of a substance from one liquid into another liquid phase.

Safety. Containing your solvent within your extraction method is safer and allows recycling.

Our extractors can be used with N-Butane, Iso-Butane, N-Propane or any mixture of the three solvents. Please contact us for compatibility with any other solvents.

The yield depends on a range of variables including, but not limited to, the method of the extraction, the temperature of the solvent, the temperature of the material, and the quality of the material. Our extractors are able to provide the maximum yield from the material packed into the column. Alternatively, you can use the extractor to maximize quality of the product over the quantity. Therefore, the yield depends on the operator and the goal of the extraction.

The stainless steel component of the extractors should be cleaned after every extraction with 91% or higher isopropyl alcohol. Be sure to take special care when cleaning Viton rubber gaskets as prolonged exposure to alcohol will degrade the gasket.

Anytime dangerous, explosive gases (Example: N-Butane, Iso-Butane, N-Propane) are used the work space should be an open, unobstructed, well ventilated area with ABSOLUTELY NO IGNITION SOURCES. We recommend operating our extractors with a hazardous exhaust system to ensure adequate ventilation is always maintained. As ignition of these gases can result in severe injury or death, extreme care should be used at all times.

The double bolt clamps should be evenly clamped down from both sides, switching from one to the other consistently. A washer should be in between the bolt and the clamp. Tighten the bolts down with a tool until you hear them squeak. The clamps should not need to be touching to be tight. 27Nm

Yes, all of our vacuum chambers have been tested to their limits to ensure they are fit for purpose.

Yes, our vacuum chambers are rated to loose no more than 2.5HG in a 24 hour period.

Yes, the chambers can be safely heated to 71*C/160*F in excess of this the user assumes all risk.

We have paired our chambers with a suitable pumps in the chamber kit section, however most vacuum pumps are compatible.
