It is produced and packaged in a 100,000-level purification workshop using ultra-clean polypropylene (PP). The workshop environment is strictly managed and controlled in accordance with the relevant standards of national standard, ISO and CE to ensure that there is no enzyme and no heat source pollution in the whole process. All products have been tested to be free of biological contamination (such as biological endotoxin, DNA lyase, RNA lyase and other biological pyrogen pollutants, etc.), and can be used in various molecular laboratories. The ultra-high-precision standard mold casting ensures that the tip can be adapted to various brands of pipettes in the market, providing users with a more flexible pipetting solution.
