Compared with single-channel pipettes, multi-channel pipettes simplify all the tasks associated with microtiter plates that often occur in immunology, biochemistry, clinical diagnosis and food analysis. Multi-channel pipettes generally have 8 and 12 heads. The gun body can be rotated at 360°C, and each part can be disassembled and repaired separately. The lower half can be sterilized at 121°C. The dimpled housing ensures a firmer grip for the operator. Can be quickly calibrated.

Application of ultra-fine metal cobalt coating technology on metal surface
The Caston metal carcass produced by Henan Yuchao Superhard Materials Co., Ltd. uses a “metal surface ultra-fine metal cobalt coating technology†close to “nano†technology in the production process, that is, on the surface of ordinary metal powder and alloy powder. The cover is covered with a very thin layer of metallic cobalt, which is only a few hundred nanometers thick, which reduces the amount of cobalt by several tens of times. Its performance is comparable to that of high-cobalt formulations, while the most advanced components are used for all active ingredients. “Cryogenic reduction process†and the use of the most advanced three-dimensional three-dimensional mixer in the world, greatly shortening the contact time between powder and air, greatly improving the low temperature activity of various powder surfaces, ensuring that the temperature is lower at lower hot pressing temperature. Effective sintering enhances the bonding force to diamond, improves the cutting utilization rate of diamond, saves electricity, saves labor and time, reduces errors, improves work efficiency, and reduces the production cost of the entire diamond cutter head to a minimum.
