Chemglass, Digital Vacuum

This digital vacuum regulator is designed to control vacuum to within ± 2 mm Hg. The controller works by opening and closing a valve between the vacuum source and the reaction.

Contoller features digital pressure entry and display, no mercury, is 100% solid state, and has all stainless steel wetted parts to resist organic solvents, acids, bases, and water.

The optional stainless steel needle valve is required for more accurate control of smaller scale distillations (<250mL). This valve will regulate the rate of evacuation and permit much finer vacuum control.
