Description
PREPARATIVE PUMP VRS 50 CO2
is unit with two pump pistons connected parallel. Flow-rates ranging is from 0,5 to 50 ml/min and maximum operating pressure of 28 MPa.
The pump is designed as built-in unit with separate mechanical and electronic parts.
For liquefied gas delivering are the pumping heads cooled using an cooling adapter. This adapter is also used for delivered medium pre-cooling. The adapter is cooled using water from external unit ( it is not include). So modified pump is used for super critical fluid chromatography (SFC) for carbon oxide pumping.
The unit is equipped with the following:
• Electronic safeguard of maximum operating pressure
• Back-flushing of pistons
• External flow rate control (using voltage)
