The quick cooling of thing sample result in sample and be limited in vitrifying matrix (such as vitrifying), and the biological sample deposited also is deposited
In the possibility of cross pollution.
Utility model content
The defect for aiming to overcome that prior art of the present utility model, a kind of cryopreservation container of stem cell, bag
Include：Container body, the container body includes proximal open end, distal seal end and the variable-diameter that extends in-between
Cavity, the cavity has an outer surface and inner surface, the inner surface from the proximal open end it is approximately radial be inwardly tapered to
The distal end simultaneously forms enclosure portion and sample reception part；Closure member, for being removably attached to the container body,
The closure member include being suitable to the cover member that is combined with the proximal open end and for table in the container body cavity
The deformable member for the conical outer surface that the hermetic unit in face is sealingly engaged.
The container body is formed by single unitary, injection-molded material injection.
The material is polypropylene, and the closure member and the container body are by identical or essentially identical thermal contraction
The material of property is constituted.
The openend of the container body includes threaded portion, and the cover member of wherein described closure member includes being suitable to
The screw thread engaged with the threaded portion of the container body.
The outer surface of the deformable member includes male cone (strobilus masculinus) shape, and the inner surface of the cavity of the container body includes female cone
Shape, and the male cone (strobilus masculinus) shape and female tapered have corresponding cone angle, and both are engaged.
The closure member also includes the rod member from its extension, and the rod member includes being used to store the near of biological sample
End, when the cover member of the closure member is fixed to described container body, the near-end of the rod member reaches the container chamber
In the sample reception part of body.
The utility model provide a kind of stem cell cryopreservation container, it is simple in construction, can bear freezen protective and
High cooldown rate and temperature range needed for vitrifying, and this tank is from external environment condition and is suitable for storage in liquid nitrogen
