G1379B Degasser

The Agilent 1200 HPLC G1379B Micro Vacuum Degasser comprises a 4-channel vacuum container, including 4 micro structured membranes, and a vacuum pump. When the micro vacuum degasser is switched on, the control circuit turns on the vacuum pump, which is operated with constant speed and voltage, generating a partial vacuum in the vacuum container. The degasser maintains the partial vacuum with the help of a controlled leak in the degasser's proportional valve.
