Step 4: Secure Tubing
Place the upper foam and rod foam pads back in
their initial positions while making sure there are
no overhanging parts.
CAUTION! If the tubing and/or foam pads are
not placed in a snug, correct manner, they can
be damaged when closing the RoSS shell.
Step 5: Close the Shell
Insert and slide stainless-steel lid back onto the
shell. You may need to push down on the foam
while sliding the lid. Close the upper stainless-steel
tabs to secure the system.
Step 6: Insert Cryo Control Unit (CCU) Supports
CCUs are used to facilitate controlled freezing. When
freezing in standard static or blast freezers, insert CCU
onto the long sides of the RoSS shell, one at a time.
The CCU should fit snuggly with the shell.
NOTE: If using a plate freezer, CCUs are not needed with
the RoSS shell. Please refer to plate freezer manufacturers’
recommended procedures.
Step 7: Lift and Place in Freezer
(Static and Blast Freezing Only)
Lift by the recessed handles on each end and place
horizontally in a freezer. For consistent freezing,
ensure the RoSS shell bottom plate is not in direct
contact with the freezer shelf.
Always use the recessed handles for carrying the
RoSS shell and use a cart for the 20 L size.
Step 8: Thawing
Inspect the RoSS system to ensure no damage
or significant bulging occurred during freezing.
The stainless-steel tabs should all be secure, and
neither the bag nor tubing should be visible.
To thaw, store the RoSS system at ambient tempera-
ture on a bench or table. Thawing can be accelerated
using a fan.
Thawing can also be done in a plate freezer, refer to
manufacturer’s recommended procedures.
