Watson-Marlow 323 Series Laboratory Pump with 313D rapid load flip-top pumphead

Benchtop pumps with manual, remote, analogue and RS232 control. The 323 is controlled with a membrane keypad and digital LCD displays speed. There are four models with increased degrees of functionality:323Du RS232/auto/manual enhanced-control high-flow pumps323U and 323U analog-auto and enhanced manual-control pumps323S high-performance manual control pumps323E manual control pumpsKey features include:Up to 133:1 enhanced digital manual speed controlManual or remote 4-20mA or 0-10V analogue auto-control or  RS232 control commandsMemoDose facility for accurate single shot dosingTwo-year warrantyDigital TTL inputs for run/stop and directionInstantly reversibleKeypad lock prevents tampering or accidental changes313 pumpheads for higher flows, 314 for lower pulsation313D and 314D pumpheads accept 1.6mm wall tubing313D2 and 314D2 pumpheads accept 2.4mm wall tubing313D and 313D2 pumpheads for flow rates up to 2000 ml/min314D and 314D2 pumpheads for flow rates up to 1600 ml/minThick (2.4mm) wall tubing provides stable flow performance with viscous fluids, or against higher delivery pressures 60 psi (up to 2 bar) or more demanding suction conditions. Because handling thicker wall tubing demands more torque, extension pumpheads may not be fitted to 313D2 or 314D2 pumpheads.313D and 314D rapid loading flip top pumpheads:Single channel pumpheads extendable up to six heads depending upon drive type and tubing bore size.
