Product Data Sheet · Laboratory Equipment
Labnics Dispensing Peristaltic Pump NDPP-205 delivers 0.0053–2580 mL/min across a 0.1–600 rpm speed range, with ±0.5% dispensing accuracy. Dispensing volumes are set from 0.01 to 9999 mL, and fixed volume, volume, speed and timed modes cover single and repeated dispensing cycles. Adjustable back suction up to 360° prevents dripping at the end of each cycle, and online calibration corrects flow while the pump runs. Rollers compress the replaceable tubing to move liquid in sealed, measured volumes without contact with the drive.
