Overview

300 series laboratory pumps

300 series laboratory pumps are a benchtop pumping solution with manual, remote, analogue or RS232 control capabilities. Featuring a chemically resistant ABS top and IP31 protection, 323 pumps have a membrane keypad that controls the pump, and a digital LCD to display speed. There are four models with increasing degrees of functionality:

323Du RS232/auto/manual enhanced-control high-flow pumps
323U and 323U analogue-auto and enhanced manual-control pumps
323S high-performance manual control pumps
323E manual control pumps

Pumphead options available as standard (others available on request):

313D and 313D2 three-roller pumpheads for continuous tubing
314D and 314D2 four-roller pumpheads for continuous tubing
314MC four-roller five-channel microcassette pumpheads
318MC eight-roller five-channel microcassette pumpheads
501RL and 501RL2 pumpheads for continuous tubing

Features and benefits

Manual or remote 4-20 mA or 0-10 V analogue auto-control or RS232 control commands
Up to 133:1 enhanced digital manual speed control
Keypad lock prevents tampering or accidental changes
