Cleaning
• Do not autoclave or heat any
part above 45 °C.
• Do not use organic solvents,
abrasives, strong cleaning
solutions, or strong acids or
bases to clean the chambers.
• Do not soak the laminated
gasket.
Note: If the old tube is cracked or
broken, protect your hand with thick
gloves, a piece of cloth, or paper tow-
els before removing the tube.
Care and maintenance
Immediately after each use, rinse the upper and
lower buffer chambers with water and then
rinse thoroughly with distilled water. Handle
the upper buffer chamber with care to prevent
damaging the banana plug. Clean gaskets with
mild detergent and rinse with distilled water.
Allow to air-dry.
Clean glass plates and spacers with a dilute
solution of a laboratory cleanser such as RBS-
35
®
, then rinse thoroughly with tap and distilled
water. Glass plates can also be treated with (but
not stored in) acid cleaning solutions.
Replacing a heat exchanger glass tube
Remove the tube by simultaneously twisting and sliding it down
as far as possible, until the top end is free of the upper grommet.
Carefully guide the tube so that it will clear the assembly, then lift
the tube out of the lower grommet.
Lightly grease the outside of both ends of the new tube with
silicone grease. Twist and slide one end of the tube into the lower
grommet. Then slip the other end into the top grommet, gently
pushing it with a slight twist until it stops.
Check that the grommet is not pinched.
