  • Cryogenic apparatus for sample protection in a dewar
    Patent number: 5419143
    Abstract: An element comprised of a cryoretentive material is adapted for insertion into and support within the inner vessel of a cryogenic dewar adjacent one or more sample holders. Such a cryoretentive element may be adapted for disposition within the canister of existing sample holders and for acceptance of one or more samples, thus permitting the convenient conversion of unprotected dewars for protection against upsets and for improved sample holding times. Such elements provide a convenient and inexpensive conversion of cryogenic dewars for shipping, an improved ability to maintain samples in a cold state for longer periods of time and an improved sample holder with protection against a loss of liquid cryogen.
