Applicable situation: Also known as micro-electrode grinder and polisher, it can grind objects with a diameter of micrometers with high precision. For example, the tip of a glass capillary for microinjection is relatively rough after being drawn which causes great damage during implantation. Therefore, it will bring a certain degree of inflammation risk to chronic surgical experiments. After using this device to precisely polish the tip, it will form a certain slope and the surface will be smooth which is conducive to puncturing the tissue, and the treated glass tube is also very good. It is suitable for cell microinjection, including oocyte fertilization in assisted reproduction .

Features: High-precision turntable, adjustable speed, the maximum speed could reach more than 7000 rpm, its vibration amplitude is within 1um, the third-generation needle grinding machine is equipped with a water circulation system, when grinding objects, the water can be significantly Increase the finish of the end face, reduce the residues entering the pipe, and the equipment is waterproof design, the equipment could work for a long time. Grinding of different material requirements by changing the sandpaper with different roughness on the turntable. The gripper section is adjustable, allowing for various angles of tip polishing. The entire gripper is controlled by micro-manipulation to realize the utilization of different positions of the turntable. In addition, a high-brightness LED light source is added which can be operated without a microscope.

Turntable error: 0.5um

Supported object diameter: 0.2-2mm

Polishing specifications: 5um/3um/1um/0.3um
