Dispensing Peristaltic Pump, 0.005 to 641 mL/min
Tube-driven pump that meters and transfers liquid without the liquid ever touching the pump, for dispensing, feeding and quantitative transfer duties.
Typical applications
- Bacterial and cell culture feed
- Animal heart perfusion
- Liquid addition to synthetic reactions
- Tangential flow ultrafiltration
- Coating and granulation liquid supply
- Laboratory dispensing and quantitative transfer

Worth knowing before you order
Flow is set by the tube, not by the pump. The 641 mL/min top figure is 18# tubing at 150 rpm and the 0.005 mL/min bottom figure is 13# tubing at 0.1 rpm, so the tube bore you buy decides the range you actually get, and no single tube spans the quoted span. Silicone tubing is a wear part — it takes a set, flattens and the delivered volume drifts — so keep tube stock and re-check the dispensed volume gravimetrically after every tube change rather than trusting the rpm setting. One pump head and one channel are supplied; parallel or multichannel dispensing needs a different head. Note the mains input is printed as AC 240 V.Specification
