After extraction, all the ethanol is reclaimed using rotovap (rotary evaporator) technology or high volume solvent recovery systems. With ethanol extraction systems, we can customize to the exact weight or volume you want to make, allowing you to do small 1pound batches to very large 500lb or more extractions. Get Details

May 07, 2017 Rotovap vs SprayVap. 05-07-2017, 10:07. I need to evaporate large quantities of ethanol whilst under vacuum and keeping the sample temp to around 40c max. So I was looking around and found SprayVap made by CES. The sprayvap does 24 liters of EtOH per hour compared to a 20 liter rotovap at 6-8 liters per hour.
