Cryo Tubes | Bag-Packed | PP | 100 Tubes/Bag
Description
Medium-volume cryogenic workflows can become inefficient when tubes are hard to distinguish, labels are unclear, or samples tip during preparation and handling.
Designed for routine 1.5 mL cryogenic storage and high-efficiency laboratory workflows, this external-thread cryogenic tube provides reliable sealing, stable handling, and fast visual identification. The yellow flat cap supports color-coded sample organization, helping users quickly differentiate sample groups during daily workflows.
Manufactured from polypropylene (PP), the tube features a self-standing bottom for stable placement during aliquoting and sample preparation. The 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.
