CryoPak Series Biological Shippers are designed for
transporting small quantities of semen, embryos, and other
biological materials at cryogenic temperatures. They
overcome the hazards of shipping such materials in
conventional liquid nitrogen refrigerators where refrigerant
can be lost by spillage.
Each biological shipper contains a unique absorbent filler
that can hold several pounds of liquid nitrogen. This gives
the shipper the holding time and capacity to fit the specific
task of transporting biological materials conveniently and
safely. When properly filled, there is no liquid to spill if the
unit is tipped over.
Materials to be stored in the shipper are normally placed in
a canister which is lowered into the shipper. The necktube
core and cap hold the canister in place. The canister and
its contents are surrounded by cold nitrogen vapor from
the saturated filter. Storage temperatures inside the
shipping cavity remain at about -320°F (-196°C) until all of
the liquid nitrogen has evaporated from the filter.
§ Advanced-Concept Absorbent – The filler material
used to hold liquid nitrogen in this unit absorbs liquid
nitrogen up to four times faster than previously used
materials. This feature speeds the process of charging
the refrigerator with liquid nitrogen and keeps stored
material cold and dry at cryogenic temperatures.
§ Optimal Holding Time – Modern materials and a
highly efficient insulation system design provide a
shipper with excellent holding times consistent with its
intended use.
§ Rugged, Dependable – Construction details such as a
rugged necktube, ribbed body support of high-strength
aluminum, a tough paint system, and a lateral support
system provide exceptional durability. The hardshell
shipping container (optional accessory) further adds to
the protection of the unit and its contents, and is
recommended if the shipper is to be transported by
commercial carriers.
§ Ease of Operation – Stored material can be inserted or
removed easily from the single 11 in. (279 mm) canis-
ter, five shelf vial rack, or nine bag blood rack. Filling by
weight adds shipping convenience. Lightweight materi-
als and ease of handling provide excellent portability.
