MST™ micro screwcap cryogenic tubes are recommended for storing blood/serum samples, cell cultures, sperm and other biological specimens at liquid nitrogen temperatures (-320°F/-195°C).
These tubes 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.
All MST™ tubes are uniform in diameter and height. Printed graduated versions are available for 1.5 mL and 2.0 mL volumes to ensure a smooth internal surface.
Available in freestanding and conical.
Caps and tube racks are sold seperately.
All of our polyethelyene MST™ tube screw caps feature a molded-in sealing ring for a rim-seal that provides a leakproof closure without the use of a silicone gasket. The screw caps come in a wide variety of colors and designed to fit all of our MST™ tubes. Available in a flat top or recessed top design.
