Description

In routine cryogenic workflows, tubes often fail in simple but costly ways: caps loosen during transport, tubes tip during handling, or bulk packaging limits flexibility in sample preparation. A reliable tube must solve everyday workflow friction—not just survive storage.

Designed for routine cryogenic storage and high-throughput laboratory workflows, this 2.0 mL cryogenic tube provides secure sealing, clear volume reference, and flexible handling in a sterile bag-packed format. The external screw cap with a blue concave design ensures reliable closure while enabling quick identification during daily use.

Manufactured from high-quality polypropylene (PP), the tube features a self-standing bottom structure for stable placement during aliquoting and processing. The integrated 1.8 mL graduation supports convenient volume reference, while the sterile, bulk bag packaging format allows efficient use in large-scale sample preparation, storage, and transport scenarios.
