Description

Handling larger-volume cryogenic samples introduces new risks: tubes become unstable during pipetting, sealing becomes less reliable under pressure, and bulk workflows demand both flexibility and consistency.

Designed for high-volume cryogenic storage and demanding laboratory workflows, this 5.0 mL cryogenic tube delivers secure sealing, stable handling, and clear volume reference in a sterile bag-packed format. The external screw cap with a natural concave design and integrated O-ring ensures reliable closure while maintaining simple and efficient operation.

Manufactured from polypropylene (PP), the tube features a self-standing bottom for stable placement during aliquoting and processing. The integrated 4.5 mL graduation supports accurate volume reference, while the sterile, bulk packaging format enables efficient use in large-scale sample storage, preparation, and transport workflows.
