Securely seal your storage tubes
Preserve the integrity of your samples with Micronic screw caps
Micronic Screw Caps for internally threaded tubes 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. Internally threaded tubes can be sealed with a standard screw cap, a Screw Cap Ultra, or a low profile screw cap.
The internally threaded screw caps are available for 96-well tubes with a standard or low profile (resulting in freezer space savings up to 33%), and are compatible with Micronic sample storage tubes in the following volumes: 0.50ml, 0.75ml, 1.10ml, 1.40ml and 2.00ml.
