Product Introduction

4.3 inch touch screen control, compact design. Display 8 pump units working parameters and working state in same screen. Friendly interface, easy operation. Split design, mainly for laboratory.

  • Each unit working independently, can set one or some units freely. Each unit can infuse or withdraw different volume in same time or different time.
  • Intelligent calibration, ensure infuse volume accuracy. Online micro adjusting function, convenient to adjust the volume of one units, decrease volume error.
  • Real time monitor, animate display monitor result. Controller can receive traffic alarm of each unit.
  • Back distance setting, can exclude bubbles inside syringe, improve volume accuracy.
  • Fast forward and backward function used for loading syringe, washing and unlock traffic protection.
