R-480 Nanoliter Microinjection Pump

Precise liquid injection in nanoliter


A microinjection pump with a glass capillary. The precise displacement of the plunger pushes the liquid in the glass capillary for nanoliter injection, and a unique seal design ensures a tighter connection and better airtightness between the plunger and the glass capillary.

The R-480 is designed for high-precision microinjection, with nanoliter volume injection using fine glass capillaries. Precise control of the internal plunger, coupled with a unique seal ring design, makes better air-tightness, ensuring the accuracy and consistency of injection.


  • Precise injection

Unique seal gasket design ensures precision and accuracy of injection;Precise plunger displacement control with error less than 1%, ensuring consistent injection volume each time

  • Easy to use

Visual touch interface with real-time display of the injection process;Auotmated injection counts by built-in software, no needs for manual counting;Multiple injection cycles can be programmed, without tedious manual Settings;Foot switch to control injection is available

  • Protective design

Experimental data can be stored well even the accidental power-off;Plug with anti-misalignment mark can safeguard instrument damage by misplacing the connection cable


  • Rodents: Stereotaxic injection of drugs, viruses, neurotransmitters or dyes into deep brain tissue in rats and mice.
  • Fish and Frogs: Embryo/larvae injection of zebrafish clawed toad and other model organisms with nucleic acid material, protein, and dyes.
  • Insects: nematodes, worms, fruit flies, cotton bollworms, rice lice, etc.
