Cryo Tubes | Bag-Packed | PP | 100 Tubes/Bag
Description
Routine cryogenic workflows can break down when tubes look identical, labels are hard to read, or small vessels tip during aliquoting and sample preparation.
Designed for routine 1.5 mL cryogenic storage and efficient laboratory workflows, this external-thread cryogenic tube provides reliable sealing, stable handling, and clear sample identification in a sterile bag-packed format. The blue flat cap supports quick visual recognition and simple operation in daily sample management.
Manufactured from polypropylene (PP), the tube features a self-standing bottom for stable placement during aliquoting, labeling, and sample preparation. The white screen-printing writing area enables clear manual marking, while the sterile bag-packed format supports flexible use in bulk sample handling, storage, and transport workflows.
