Description

In medium-volume cryogenic workflows, sample confusion and inconsistent labeling can quickly compromise efficiency—especially when tubes lack clear differentiation or stable handling during preparation.

Designed for routine 1.5 mL cryogenic storage and organized laboratory workflows, this external-thread cryogenic tube provides reliable sealing, stable handling, and enhanced visual identification. The green flat cap enables intuitive color-based organization, helping streamline multi-sample workflows.

Manufactured from polypropylene (PP), the tube features a self-standing bottom for stable placement during aliquoting and processing. The white screen-printing writing area supports clear manual labeling, while the sterile bag-packed format enables flexible use in bulk sample handling, storage, and transport.

Features

● External Screw Cap Sealing — External-thread design ensures secure closure for routine cryogenic storage and sample transport.
● Green Flat Cap for Workflow Organization — Distinct cap color supports color-coded sample grouping and improves workflow clarity.
● White Screen-Printed Writing Area — Dedicated labeling surface enables clear manual marking for accurate sample identification and tracking.
● Self-Standing Bottom Structure — Stable base minimizes tipping during pipetting, labeling, and sample preparation workflows.
● Polypropylene (PP) Construction — Durable material supports cryogenic storage and repeated laboratory handling.
● Sterile Bag-Packed Format — 100 tubes per bag supports flexible bulk usage in high-throughput laboratory environments.
