Description
Cryotubes with external screw cap, 2 ml, round bottom are compact cryovials intended for secure low-temperature sample storage. Produced from pure polypropylene (PP), they feature a stopper with a silicone seal that enhances tightness during freezing, storage and handling. A writing surface on the tube body supports clear labelling in laboratory and biobank environments. The vessels may be used from −196 °C to 120 °C, enabling both cryogenic archiving and standard thermal laboratory steps. Certification confirms they are DNase-free, RNase-free and pyrogen-free, and a sterilisation certificate is available for free download. Delivered in packs of 50 pieces from manufacturer Labbox, the round-bottom profile suits rack-based storage systems and workflows where a classic cryovial geometry is preferred. Typical uses include cell culture aliquots, clinical and research specimen banking, and molecular biology samples that require leak-resistant, purity-controlled containers with reliable identification space.
This article is part of Cryogenic vials & tubes, in Cryogenics & cold storage.

Questions about Cryotube with external screw cap, 2 ml, round bottom, 50 pcs
What is this article?
Cryotube with external screw cap, 2 ml, round bottom, 50 pcs is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Cryogenic vials & tubes, inside Cryogenics & cold storage, in Lab consumables.
A cryogenic vial is a small tube with a seal made for very low temperatures. Internal and external threads differ. A vial that will see liquid nitrogen has to be rated for it, and it should not be overfilled, because trapped liquid expands. The cap insert is part of the seal.
Cold storage slows chemistry and keeps cells, proteins and nucleic acids from falling apart. A cryogenic vial is made to survive liquid-nitrogen temperatures and to be sealed against the liquid. A box and a rack are how those vials are found again. The article is not part of free standard delivery when it must stay cold: cold-chain goods are never included in that free delivery. Biosafety of the material inside is summarised by the WHO laboratory biosafety topic. Reference lines are held by ATCC.
