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.

Features

● External Screw Cap Sealing — External-thread design ensures reliable closure for routine cryogenic storage and sample transport.
● Red Flat Cap for Rapid Identification — Distinct cap color enables immediate visual recognition and supports color-coded workflows to minimize sample confusion.
● White Screen-Printed Writing Area — Dedicated labeling surface allows clear and durable manual marking for accurate sample tracking.
● Self-Standing Bottom Structure — Stable base minimizes tipping during pipetting, labeling, and sample preparation.
● Polypropylene (PP) Construction — Durable material supports cryogenic storage conditions and routine laboratory handling.
● Sterile Bag-Packed Format — 100 tubes per bag supports flexible usage in high-throughput workflows without requiring rack-based systems.
