PURline™ Sterile Microtubes

PURline™ tubes are manufactured under clean room conditions, using an advanced polypropylene that maximizes clarity, centrifugal strength (tested up to 28,000 x g) 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 PURline microcentrifuge tubes are RNase, DNase and pyrogen free.
