PERIPRO-4LS

Overview

• Fluid Flow Range: 0.1-80mL/min; #14 tubing: 0.2-18mL/min
• Tubing Range: 0.5-2.4 mm ID
• Rotor Speed Range: 1-100rpm
• Large backlit digital LCD display
• Display either rotation speed (RPM) or flow rate (mL/min)
• Accuracy of flow rate: 0.5% using self calibration function

Accurate and precise pumping

Peri-Star Pro peristaltic pumps provide accurate and precise pumping with convenience and versatility. Peri-Star Pro can be run in either flow rate mode (mL/min) or rotation speed mode (rpm). For good laboratory practice, pumps must be calibrated after changing the tubing and solution. Users can easily calibrate Peri-Star Pro to deliver flow as accurate as 0.5% in a wide flow range from 0.01 mL/min to 280 mL/min. Under rotation speed mode, the digitally controlled stepping motor provides accurate and reproducible operation with 0.1% rpm both forward and in reverse.

Easy to use

Large backlit digital LCD display provides readouts of rotation direction, flow rate or rotation speed, tubing ID, drive status and remote control mode simultaneously. Water resistant membrane keypad allows easy programming while protecting LCD display and controls from fluid entry. Built-in Human Machine Interface (HMI) with screen instructions in plain English steps users through initial setup, calibration and operating procedures. The user-friendly interface reduces the need to frequently check the printed manual for instruction and reference.

Rollers

Peri-Star Pro is available in two versions: a 4-roller version for high flow and an 8-roller version for lower volumes while providing high pressure with minimal pulsations. A unique planetary gear design with eight actively driven rollers (four rollers for higher flow rate model), together with independent tubing compression fine adjustment, greatly increases flow accuracy and prolongs tubing life. Snap-on cartridges allow tubing to be changed quickly without cross contamination of solutions.
