Watson Marlow 205U Multi channel cassette pump

Watson Marlow 205U Multi channel cassette pump

 

The 200 series multi-channel scientific pumps provide high-precision pulsation-free pumping.

 

205U auto and manual control variable speed pump.

 

Fitted with tachometer-controlled servo-quality DC motor for precise speed control. A keypad lock prevents tampering or accidental changes and there is a maximum high speed priming function.

 

Flow control for each individual channel is provided by multi-turn "click-stop" pressure adjustment on each cassette. The 205CA pumphead with its snap-fit cassettes and sprung track is factory-set for standard applications,but lockable occlusion adjustment allows settings to be optimised when necessary and, uniquely, remain undisturbed during tube changes. 0-5V DC tachometer output for speed monitoring, 5V auxiliary output for motor run indication. Remote low voltage, or TTL (PLC compatible) control of start/stop and direction.
