Product Introduction

This product focuses on the high-precision transmission and distribution of "micro-upgraded" level liquids. The core lies in the coordinated control of alternating dual execution units and directional valves, achieving a true "constant flow injection" - that is, achieving uninterrupted liquid transmission while retaining the high precision of traditional microsyringes.


Product Features

  • Constant-flow delivery mechanism: Two actuator units alternately perform aspiration and dispensing, combined with a directional valve for flow switching, fundamentally eliminating pulses and intermittent flow that occur during the switching cycle of conventional syringe pumps.
  • Operation mode: Continuous delivery
  • Split architecture: Separate controller and actuator unit
  • Safety protection: Closed-loop control and overload protection
  • User-friendly interaction: 7-inch LCD screen for easy operation
  • Communication interface: One-touch start, compatible with automated system integration
