Storage Tubes with External Thread

Micronic released 0.75ml and 1.40ml tubes with an external screw thread.

The two tube sizes are the first in a range of new designs featuring an external thread. Using externally threaded tubes for sample storage eliminates the possibility of the sample coming into contact with the screw thread, greatly reducing the chance of cross-contamination while improving sample integrity. Due to thick tube walls, the tube has a sturdy design and excellent properties for ultra-low temperature storage.

Externally threaded tubes allow for a higher (net) volume of material to be stored inside, which means that the sample tubes can hold more while occupying the same amount of storage space. The triple thread of the tubes gives an excellent closure and horizontal placement of the cap to ensure long-term sample preservation and storage.
