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.

• Patented control eliminates baseline fluctuations
• Inert flow path
• 5+ year lifetime
• Built-in anti-backflow check valves
• Compact

Fluctuations in detector baseline due to changes in vacuum level are eliminated by not having to repeatedly stop and start a single-speed pump. This also greatly reduces wear and noise. The brushless motor enables quiet operation and is appropriate for environments where solvent vapors may be present. Flowpaths are entirely inert and the continuously purged head design allows the pump to start into a full vacuum – vacuum will not be released in the event of a power loss.
