Achieving Ideal Vacuum in Concentrating Extract Using a Rotary Evaporator

Filtering winterized extract is a game of time. You need to pull the crude oil and ethanol through the filter and leave behind the frozen lipids, fats, and waxes before they thaw. If they do thaw, a lot of time and money will be lost. Finding a pump that provides a strong vacuum in just the right range is a must.

Vacuum That’s Just Right

Filtering winterized extract fast is critical to prevent frozen lipids, fats, and waxes from thawing and being collected with your crude oil and ethanol. Too little vacuum provides a weak pull and slow filtration. If the vacuum is too deep, then you will evaporate off the ethanol and it will be exhausted out the pump. Using a pump that delivers the right vacuum level with enough flow to overcome any leakage in the filtration process is what is needed to get the job done fast.
