Sample Amount
Question: What is the minimum amount (in gram) of sample that can be processed using the SFT-150?
Answer: The SFT-150 SFE can accommodate sample vessel sizes from 100mls up to 2000mls. Now depending on the density of your raw materials you can typically get a “fill” of raw materials on 50 up to 80% of the vessel volume. So in effect it really depends on your density of materials to extract and then your volume of processing vessel to get a feel for number of grams that can be processed.
