Ace Glass 14061-08 DVR-200 Vacuum Regulator 120VAC

Model DVR vacuum regulators are designed for vacuum systems that run continuously, such as oil filled vacuum pumps, aspirators or with in-house systems. The DVR regulates pressure by opening and closing a valve that separates the vacuum source from the system being evacuated. No mercury, wetted parts are Stainless Steel or PTFE, USB port, built-in transducer and free control software included. 120V.

Connect to any vacuum pump or vacuum source, and then to any piece of equipment, to regulate pressure, in most cases to ±1 Torr. A standard pressure ramp feature evacuates equipment at a user-defined rate to eliminate bumping due to solvent degassing or over-evacuation. Ideally suited for large volume distillations, rotary evaporators and vacuum chambers. Not recommended for small volume distillations or applications which involve a continuous purge with gas. Designed for vacuum systems that run continuously, such as, oil-filled vacuum pumps, aspirators, or with systems that are "always on," like in-house vacuum systems. The unit regulates pressure by opening and closing a valve that separates the vacuum source from the system being evacuated.
