The 400 series is Watson-Marlow’s range of instrument-quality ultra-compact pumps. All are ideal for bench top applications and there is a choice of single and multi-channel pumpheads. Each pumphead is precision machined and has its own tube compression adjustment ensuring superior set-up accuracy and repeatable flow rates.

All cased drives have manual and auto analogue speed control and remote switching. The pumphead range utilises standard 1.6mm wall and two and three bridge standard laboratory manifold tubing.
