This vacuum pump is designed for use with aqueous samples that are compatible with FreeZone Freeze Dry Systems, CentriVap Centrifugal concentrators and Protector® Controlled Atmosphere glove boxes. It comes with a single phase direct drive motor, totally enclosed and fan cooled. When the motor overheats, the thermal overload device switches off the pump. When the pump cools down, the motor automatically restarts. Isolation valve seals the inlet to prevent oil and air contamination of the system in the event of power failure.
