Sterile MST Micro Screwcap Tube
Caplugs Evergreen Sterile MST™ micro screwcap tubes are recommended for storing blood/serum samples, cell cultures, sperm and other biological specimens at vapor phase* liquid nitrogen temperatures (-320°F/-195°C).
- Available in conical or freestanding versions
- Feature a built-in flange at the neck of the tube to further reduce the possibility of leakage and provide a ridge on the surface of the tube for minimal surface contact during transport
- Uniform length of MST tubes allows for maximum and efficient use of storage space when storing MST Tubes of mixed sizes.
- Printed graduated versions
*Evergreen does not recommend the use of MST™ micro screwcap tubes for immersion in liquid nitrogen or any other liquified gases. Immersion in liquid nitrogen may cause potential leakage in MST™ tubes with the subsequent danger of rapid pressure build-up and/or explosion when returned to room temperature. Please use MST™ micro screwcap tubes in the vapor-phase only.
