LONGER BT-300-2J peristaltic pump
The LONGER BT-300-2J peristaltic pump runs at 1–300 rpm (1 rpm resolution) with a flow range of 0.07–1,140 mL/min depending on pump head and tubing size. The liquid touches only the pump tubing, so there is no cross-contamination. It offers four control modes — panel keys, foot switch, external analog signal (4–20 mA / 0–10 V) and RS485 communication — for continuous transfer in chemical dosing, food processing and biotech testing.
