Abstract
A system for the transferral, freezing, storage and processing of liquids with a minimum of contamination is described. The components of the system include a hollow disc-shaped vessel of special construction which permits rapid freezing at extremely low temperatures, a pierceable, resilient sealing member on the ports of the disc-shaped vessel and a pointed cannular needle which is protected from contamination prior to use and operable to pierce the sealing member free of any contamination.
Claims2
A container for use in the rapid freezing of liquids through immersion in liquid refrigerants and in the subsequent storage and processing of the frozen or thawed liquids comprising a hollow, disc-shaped vessel having a volume at least 50 percent greater than that of the liquid to be frozen, said vessel being made entirely of double annealed borosilicate glass having a low coefficient of expansion and consisting essentially of an annular outside wall of uniform thickness and convex cross-section. a pair of substantially flat and parallel faces continuously joined to and integral with the edges of said annular wall, and three parallel tubular ports in communication with the interior of said vessel and projecting from and integral at one end with the annular wall and terminating at its other end below the intersection of its axis with a line perpendicular thereto and tangential to said annular wall, said ports being disposed within an arc of the annular wall of less than 180.degree. in a plane parallel to said faces.
