Description

Larger cryogenic samples need more than extra volume: the tube must seal securely, stand steadily during handling, and remain convenient for bulk laboratory workflows.

Designed for routine 2.0 mL cryogenic storage and flexible laboratory workflows, this internal-thread cryogenic tube provides secure sealing, stable handling, and clear volume reference in a sterile bag-packed format. The natural concave cap with O-ring supports reliable closure while keeping the tube simple and easy to operate.

Manufactured from polypropylene (PP), the tube features a self-standing bottom for stable placement during aliquoting, labeling, and sample preparation. The integrated 1.8 mL graduation supports convenient volume checking, while the sterile bag-packed format allows flexible use in routine sample storage, preparation, and transport workflows.
