HPLC Column Washing Pumps
The high performance liquid chromotography (HPLC) pump is designed to be a reliable component within a basic analytical or sophisticated research instruments. While ideal for HPLC applications the pump is also useful as a column washing pump for washing analytical HPLC columns.
The flow rate of the pump fitted with the standard 10 ml pump head can be set in 0.01 ml increments from 0.01 to 10.0 ml/min. size is availbale in type 316 stainless steel or biocompatible (metal free) PEEKTM.
The low pulsation flow produced by the reciprocating, single piston pump is achieved by using an advanced rapid-refill cam design, programmed stepper motor acceleration, and an internal pulse dampner.
Pump Features :
- Can easily be modified for analytical and semi-preparative techniques.
- Incorporates a diaphragm - type pulse dampner which reduces pulsation in the system by as much as 90%.
- Integrated prime / purge valve.
- Self-flushing pump head.
- LED readout on the front panel - shows the flow rate.
- Tactile response, chemically resistant front panel keypad.
- Microprocessor advanced control.
- Digital stepper motor design prevents flow rate drift over time and temperature, which is a common problem found in analog design.
- Back panel RS232 serial communications port for complete control and status monitoring.
- Quickset Software.
