These secure-lock microcentrifuge tubes offer a special locking clasp to produce a more secure closure. This will prevent tubes from opening during centrifugation, boiling, storing, freezing and shipping. They are graduated at 0.5, 1.0 and 1.5 ml. They are autoclavable to 121°C. Pierceable lid. Capacity: 1.5 ml.

All 1.5 ml SIMPORT microcentrifuge tubes offer a CLIKLOK® seal especially designed to reduce popping where freezing, boiling, storing or shipping is required. This superior quality CLIKLOK® system works in two stages:
1. If spinning is to be done, only a slight push of the cap over the tube is required.
2. For optimum seal, further pressure on the cap snaps it in more tightly, and assures an optimum seal.
