This 1 gallon mini unit works amazingly! Great compact size doesn't take up a ton of room, and doesn't require you use a ton of product to get meaningful results.
Load your dry product in along with ice or dry ice, shake, and there you have it, only the desired product slips through the 120 micron screen sewn right into one side of the zip up bag, with a non-stick same sized plastic mini barrel that goes right inside the screen bag. Best bang for the buck by far!
Give one try, you'll definitely be pleased with the results and how effortless a procedure it is!
