3.2 Prepare the unit

To disassemble a fully assembled unit: Remove the
safety lid by pressing on the handle at the top of the
upper buffer chamber core while lifting the lid by the
bottom edges. Empty all buffer chambers and remove
any gel sandwiches. Then depress both release tabs
and lift out the upper buffer chamber core.

Rinse the instrument before each use. Before using the
first time, disassemble the unit completely and wash
with a dilute solution of a laboratory detergent and
thoroughly rinse with water and distilled water.

Check the gasket. Periodically remove the gray silicone
rubber gasket from the core. Inspect for nicks and
wear. If the gasket appears to be intact, apply a
light
film of Gel seal, and replace it in the groove. Avoid
stretching the gasket by laying it onto the groove and
pressing it into place.

Optional cooling.
Circulating pressure must not exceed 0.8 bar (12 psi)
above ambient pressure. Do not connect the cooling core
to an unregulated coolant source such as a water tap.
Connect the cooling core to a circulator bath such
as the MultiTemp III. Slide hose clamps (4 total)
onto each end of two lengths of 8 mm (5/16”) vinyl
or silicone tubing. Attach one end of each length of
tubing to a cooling core port. Attach the free ends of
each length of tubing to the circulator bath ports; one
to the inlet and the other to the outlet. Secure the
connections with the hose clamps.

Important! Use only water
or water and
≤
50% ethylene
glycol as a coolant. Do not use
a commercial antifreeze or any
alcohol-based mixture.
Note: If the cooling option is
used frequently, it is conve-
nient to attach QuickFit
connectors to the tubing.
The valves in these fittings
prevent coolant spillage.
