400/A series panel mount pumps
Overview
400/A compact micro-flow pumps
For precise control of low flow rates, the 400/A is the smallest pump in our range. There is one version for continuous tubing, and another for tube elements. It is available with a range of simple DC motors as well as a stepper motor for greater speed control. It is available in black and white, or custom colours. Also available as pumpheads only.
Features and benefits
- Flow rates from 30 µl/min to 30 ml/min
- Instrument quality in very compact size 31 x 48 mm
- Spring-loaded track for precision and extended tube life
- For 0.85 mm and 0.9 mm tube wall thickness
- Compatible with continuous tubing or tube elements
- 12 V and 24 V DC drives with a range of maximum speeds
- Pumphead available in standard or high pressure
