sufficient to seal the vial. Closure and vials are both manufactured of polypropylene with the same coefficient of expansion, which ensures an equally secure seal both at room temperature and at
low cryogenic temperatures.. A specially designed lip inside the cap ensures a leakproof seal for the cryovial even at very low temperatures.Tubes have a white marking area, can be color coded by
using a capinsert (series t312) and are compatible with most storage systems. Only the round bottom vial can be centrifuged, and up to 14,000g. Vials are sterilized by gamma radiation and are
