R-480 Nanoliter Microinjection Pump

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.


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.

Clients Say

The R-480 is excellent and the experience of using it is much better than other equipment which I previously used in our lab.For example, the design of the gasket is not necessary to remove, what's more, the glass micropipette can be inserted directly, and the airtightness is awesome. In addition, a light press on the reset button will bring the needle directly back to the home position.By the way, the maintenance cost of R-480 is lower than the previous.
