Locking Lid Microcentrifuge Tubes

Offering extra sample security while maintaining an easy to open cap, the QSP Locking Lid Microcentrifuge tubes provide a superior lock for safe and convenient centrifugation, boiling, freezing, incubation, or sample storage. The cap snaps closed and the lock easily slips into place with a simple one-hand operation. The larger round cap design proves less stressful to the thumb and the smooth surface reduces the possibility of ripped or torn gloves. Colors available are red, blue, green, yellow, orange, and violet. To order colored tubes, add the letter of the color to the end of the catalog number. (i.e. L-510-GRD-R, which is a red tube). For mixed colors order L-510-GRD-MIXED (includes all colors, except natural).
