The methacrylate dryer for processing extractions supports a vacuum of -740 mm of Hg with a loss (absolute zero: -760 mm / Hg) of not more than 20 mm of Hg in 24 hours.
The transparent upper cap is molded in polycarbonate and is coupled to the lower section in PP, ensuring the seal by means of a neoprene rubber ring inserted in a special groove.
The lid is equipped with a polycarbonate sealing valve with a PE pin which, with a slight rotation, allows air to enter without turbulence. A thin film of grease spread on the sealing ring helps to create the initial vacuum. The dryers have an internal basket that serves as a container for calcium chloride or other drying agent.

General guide to use:
