Product Introduction

Constinfuse-constant flow syringe Constinfuse-constant flow syringe pump, focusing on microliter volume liquids continuous transferring and dispensing.
Flow rate range: 0.06μL~70mL/min, continuous flow.
Support RS232 and RS485 communication for external control.
  • High precision and uninterrupted transferring of micro-liter liquids.
  • Four working modes: Continuous transferring; Fixed volume measurement; Dispensing; Timing start/stop.
  • 4.3-inch industrial-grade true color LCD screen display, friendly operation interface and synchronous simulation animation, allowing users to operate conveniently.
  • Multiple external control interfaces to meet various supporting needs.
  • Record the number of times the valve and syringe are used, which is convenient for equipment maintenance;
  • The pump unit supports "offline" operation, which enables one controller to set different parameters for pump units, which is convenient for users to use together with other equipment.
  • The controller has offline reminder and parameter synchronization function.
  • Intelligent calibration function.
  • Closed-loop control, overload protection function, effectively protect the syringe.
  • Quiet design.
  • 304 stainless steel spray shell.
