Vacuum Traps

Placing vacuum traps between an apparatus and vacuum source establishes a safe and controlled working system. The glassware protects the pump from the separated solvents while simultaneously preventing vapors from being emitted back into the system. Vacuum traps in reservoir, one piece, or two piece styles also guarantee that personnel will not be exposed to gases produced that could be harmful. Standard sized inlet and outlet stems can snugly fit regular stoppers.
