The UNi-S100 fully automatic blood collection tube decapping machine is used for automatic decapping of blood specimens before testing. It can replace the manual decapping operation of existing blood collection tubes, reduce the labor intensity of medical staff, and improve the laboratory environment. The instrument is equipped with a HEPA filtration system and a UV disinfection system to avoid cross-contamination of specimens and protect the safety of medical staff. One-click opening of the lid is easy to operate. The standard multi-functional test tube rack has an anti-slip function to prevent the test tube rack from tipping over and causing the test tubes to fall off.
