CAT M. Zipperer Micrometering pump HPLH 20 VCS 70947-0000

The successful microprocessor controlled pump.
The system consists of an ergonomic pump housing and a detachable programming and operating unit with key-pad and alphanumeric display.  All relevant parameters, e.g. volume, flow-rate and flow direction, are set via the key-pad on the control unit, which can be used remotely from the pump. The key-pad has 3 function- and 2 hot-keys, plus an analogue encoder wheel for fast data entry, enabling intuitive adjustment of the set values. The back-lit LCD shows both set and actual volumes, flow-rate, and other functions.
A choice of units of volume, flow-rate and specific weight can be pre-programmed, e.g. µl, ml, mg, g, µl/s, ml/m. The PCON C controller has a RS232 interface as standard (1200-4800,8,N,1) and the analogue and digital I/O ports provide full flexibility.
Connection to the analogue input allows the pre-programmed flow-rate to be overridden by a voltage or current signal. The analogue output (0-10 V and 0-24 mA) can then be used to record and read out the actual flow-rate.
The pump heads are encased in robust stainless steel bodies and are available in 20 µl, 200 µl, 400µl and 1000 µl stroke volumes. They are also available with or without piston rinse port. The models "VCS" have a rinse port integrated into the ceramic cylinder, no piston sealing is necessary.
All wetted parts are made of ceramic (99,7% Al₂O₃), PTFE or ETFE
Pumps with built-in rinse pump for piston rinsing are available.
 
The pumps have incorporated software programs for many applications:

• STANDARD DISPENSE - dosing of a preset volume
• DILUTOR - diluting of a solution
• PIPETTE - simulation of a pipette
• DELAYED DISPENSE - an electronic dropping funnel

Applications:

• precise dosing of a set volume
• manual dispensing
• time-controlled dispensing
• titrating
• diluting
• regulated drop-dispensing
• sampling with and without an air-segment
