Supercritical Fluid Pumps

PU-2080-CO2 CO2 delivery pump for supercritical fluid chromatography and extraction

The PU-1580-CO₂ is a liquid CO₂ delivery system for supercritical fluid applications. The essential units (pump, pump head cooling unit and controller) are integrated for easy operation and reliablility. The PU-2080-CO₂ consists of:

Solvent delivery pump providing uniform flow via SSQD system (Slow Suction Quick Delivery)
Pump head cooling unit which maintains temperature of the pump heads below -4 °C via an electric cooling method.
System control unit offering range of operation modes including modifier addition.
