Securely seal your storage tubes

Preserve the integrity of your samples with Micronic screw caps

Micronic’s externally threaded screw caps securely seal tubes for long-term sample storage at ultra-low temperatures. To meet the diverse needs of different researchers, Micronic offers a range of sealing solutions. Externally threaded tubes can be sealed with standard screw caps for tubes with external thread—caps that are available for the following tubes sizes: 0.30ml, 0.75ml, and 1.40ml (96-well), 1.00ml and 4.00ml (48-well), and 3.50ml (24-well).

In addition to the standard Screw Cap for Tubes with External Thread, NBS Scientific also offers the Screw Cap IG that has an improved gripping for both manually and automated handling, the newly designed lead-in on top of the screw cap ensures a better tube placement and the lower height makes storage (without rack cover) in automated stores more efficient.
