ABSTRACT:
The present invention is an improved sealable vial for storage of materials. The vial includes a tubular body portion sealed at one end and provided with an aperture at the opposite end. The tubular body is further provided with a male spiral thread about the aperture end and a tapered section extending inward from the aperture. A sealing insert is attached to the body for positioning in either a closed position wherein it seals the aperture or an open position wherein the aperture is open. A cap fits over the sealing insert in the closed position and seals the vial. The cap includes female threads which mate with the male threads of the tubular body to secure the closure.
The vial is particularly adapted for cryogenic storage of organic samples. The vial is also adaptable to other applications wherein complete sealing is required under wide temperature and pressure range conditions. The improved seals provided by the interface between the sealing insert and the tubular body prevent leakage into or out of the vial.
