Systec ZHCR Degassing Pump

Systec ZHCR Vacuum Pump, Preparative bottom mount

Description

The Dual Stage Pump (DST) is a vacuum control system for use with IDEX degassing chambers and PCB control systems. The prep versions are designed to handle high vapor loads from high flow rate chambers or fluids with low vapor pressure that will cause increased solvent pervaporation through the membrane. The pump is also available in side mount versions.
