Digital Vacuum Regulator ∙ 120 Vac ∙ Catalog# DVR-200
$1,365.00

An ideal instrument for laboratory vacuum regulation. 


Connect the regulator to any vacuum pump or vacuum source and then to any piece of equipment to regulate pressure in most cases to ± 1 torr. 


A pressure ramp feature evacuates equipment at a user defined rate to eliminate bumping due to solvent degassing or over-evacuation. 


The vacuum regulator is ideally suited for large volume distillations, rotary evaporators and vacuum chambers. 


Recover > 99% of solvent from rotary evaporators


Features:


NO Mercury


100% digital pressure entry and control


Wetted parts are 100% stainless steel and Teflon


Vacuum ramping feature eliminates bumping


USB port and free software for PC control


Resists: All organic solvents Acids Bases Water


Not recommended for small volume distillations or applications which involve a continuous purge with gas, these applications are better performed by J-KEM’s Precision Vacuum Regulator, Model DVR-1000.


Two Styles of Regulators to Choose From


Model DVR-200


Designed for continuous vacuum sources, such as oil-filled vacuum pumps, aspirators, or systems that are “always on”, like in-house vacuum systems. The DVR-200 regulates pressure by opening and closing a valve that separates the vacuum source from the system being evacuated. In most cases, the DVR-200 is the best choice.


Model DVR-280


Designed for use with diaphragm vacuum pumps that regulate pressure by turning the pump On and Off. The DVR-280 doubles the life of diaphragm pumps by starting the pump at atmospheric pressure before connecting it to the vacuum system.
