Stop-Pop™ CapLock

Our SureSeal S™ microcentrifuge tubes are designed for a broad range of research applications, including enzyme digests, DNA isolation/purification, centrifugation, incubation, and general sample/reagent storage.

SureSeal S tubes are manufactured under clean room conditions, using only BioClear™ co-polymer, an advanced polypropylene that maximizes clarity, centrifugal strength (tested up to 28,000xg) and the usable temperature range (-90°C to +121°C).

The oversized tube cap (with frosted marking surface), combined with the unique ring & groove closure, enhances the security of the liquid-tight seal, while minimizing the required locking forces for a more ergonomic opening/closing of the tube caps.

All SureSeal S tubes are RNase, DNase and pyrogen free.
