The Systec ZHCR (Zero Hysteresis / Constant Run) Analytical vacuum pump is designed for membrane degassing of the HPLC mobile phase. Employing a patented closedloop, micro-stepping, RPM control-strategy permits the pump to run with continuously variable speed, providing quick pull-down at high RPM, and then sustaining a consistent vacuum level at low RPM. -

Employing a patented closedloop, micro-stepping, RPM control-strategy permits the pump to run with continuously variable speed, providing quick pull-down at high RPM, and then sustaining a consistent vacuum level at low RPM. -
Stented/GPC compatible degassing chamber- the first choice for 100% organic solvents. Our Prep/Semi-Prep Scale Degassing Chamber is built for the rigors of modern preparative and semiprep scale HPLC. Its unique design assures reliable continuous operation and the highest level of continuous performance available. The chambers are available in single or dual channel configurations, allowing two solvent lines to be degassed simultaneously by one unit. -
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.
