Description
In fast-paced laboratory environments, small-volume samples are prone to mix-ups when tubes look similar, labels are unclear, or handling becomes unstable during preparation.
Designed for precise 0.5 mL cryogenic storage and high-efficiency laboratory workflows, this external-thread cryogenic tube provides reliable sealing, stable handling, and clear visual identification. The red flat cap enables rapid recognition, supporting color-coded sample management and reducing handling errors.
Manufactured from polypropylene (PP), the tube features a self-standing bottom for stable placement during aliquoting and sample preparation. A dedicated white screen-printing writing area enables clear manual labeling, while the sterile bag-packed format supports flexible use in bulk sample handling, storage, and transport workflows.
