Tamperproof Micrewtube Products

How Does It Work?

MTTP works

At last, a TAMPERPROOF microcentrifuge tube incorporating all the features and benefits of the Simport Micrewtube Family. Ideal for all applications requiring a tamper evident seal, a Simport tamperproof Micrewtube® also has a multitude of benefits when used in your lab. It is ideal for freezer storage, boiling applications, centrifugation etc. and will fit most standard microcentrifuge rotors.
 Simply screw the cap on the tube and the tamper evident sealing ring is automatically in place. When unscrewed, the ring is detached from the tube and remains in its position, showing clearly that the tube was opened. The flat cap facilitates manipulation especially in aseptic procedures. It does not incorporate an attachment loop for users who prefer to remove it completely from the tube when filling or sampling. The o-ring secured in the cap ensures a positive leak proof seal, time after time, keeping the integrity of small samples under even the most adverse conditions. The tamperproof Micrewtube cryogenic vial is available in many varieties of sterile and non sterile configurations. The tubes are available non-printed or printed with graduations and white marking area for sample identification. They also can be centrifuged up to 17,000g. Sterile tubes are gamma irradiated and packaged in tamperproof resealable bags to protect remaining tubes from contamination. Sterile tubes are also available with printed graduations and white marking area for sample identification. Tubes and caps are also available separately.
