The product consists of a clamping rod, a V-shaped clamp, a clamping ring, and a clamping head precision differential cylinder (with an accuracy of 1 grid 0.01mm), and V-shaped grooves are carved in the three directions of the clamping head to facilitate the clamping guidance of the injection needle or electrode. The PEI material of the clamping head has electrical insulation performance, radiation resistance, high and low temperature resistance, and wear resistance, and can pass through microwaves. PEI also has good flame retardancy, chemical resistance, and electrical insulation properties. Used for micro syringe administration experiments, it can simultaneously fix the syringe barrel and needle, making the clamping of the syringe more stable. The clamping range of the syringe barrel is 3mm-12mm, and the clamping range of the syringe needle is 0.3mm-1.5mm.

In the operation of brain stereotaxic devices, it is often necessary to perform microinjection on animals. A manual microinjection pump can be used, which is convenient to use. The syringe syringe can be directly installed on the gripper, and the precise movement of the syringe piston can be controlled by a micro thruster to directly inject or recover liquid from experimental animals, avoiding errors caused by the use of catheters. This injection pump is compatible with most imported and domestically produced microinjectors (1ul -100ul), with a displacement accuracy of 10 μ m (meaning that for every small grid rotation, the syringe piston advances by 10um), and can advance up to a distance of 25mm.

This product is an upgraded economy version of the M5120 injection clamp; Compared with more complex electronic controlled brain stereotaxic devices, manual microinjection pumps are cheaper and easier to operate.
