1.5 ml Safe-Lock Microcentrifuge Tube Transparent Polypropylene Pack of 500

1.5 ml microcentrifuge tube in transparent polypropylene with latch-lock closure. The locking tabs engage the tube body and prevent the cap from opening during centrifugation — the primary failure point with standard snap-cap tubes. Flat integral cap, one-hand opening, pierceable wall for direct needle sampling without uncapping.

Applications

Storage and centrifugation of small sample volumes in molecular biology and biochemistry. The latch-lock closure is particularly suited to high-speed protocols where an open cap means sample loss and cross-contamination.

Routine use in PCR, DNA/RNA extraction, ultra-low temperature sample preservation, and any protocol involving repeated centrifugation cycles.

Latch-lock closure

The cap's lateral tabs engage the tube body and hold against centrifugal force up to 20,000 x g — no parafilm or additional sealing required. The cap remains easy to open one-handed for routine bench and biosafety cabinet work.
