Micronic offers the most extensive range of tube capping products, including screw caps and push caps, in the market. For effective cryogenic storage a screw cap is recommended since it allows for the tightest seal possible. For storage from -80°C and above, either a push cap (TPE Capcluster) or Screw caps can be used. All tubes have an upper screw thread or double O-Ring design providing a perfect seal and closure ensuring maximum sample integrity. The Micronic push caps are available in 96-format and the screw caps in 96-, 48-, 24-format. All sealing products are available in a range of colours.
