For those wanting to extract the most potent and pure concentrates, vacuum purging is a must. While extracting with solvents, it is important to make sure there are no residual solvents trapped in your sample at the end. Across International makes removing these residual solvents easy with their vacuum purging supplies.
What how does vacuum purging work?
When putting a sample in a vacuum oven and using a vacuum pump, you can lower the boiling point of the solvent. This will remove it from the sample without degradation, preserving the potency and profile of your extract.
By using a cold trap, also known as terp traps, with your vacuum purging system, you can preserve the terpenes of your extracts. Without one, terpenes could be purged off, and the life of your vacuum pump would decrease.
