2.1 PREPARING THE VACUUM SYSTEM FOR USE
CryoCool.
Prepare the vapor trap by dispensing the correct level of CryoCool
® Heat Transfer
Fluid (SCC1); available separately. Pour 800 ml of CryoCool into the stainless steel
trap chamber. A line scribed in the wall of the stainless steel chamber indicates the
minimum appropriate CryoCool level (with glass flask not yet inserted). When replen-
ishing CryoCool, add more fluid until the level reaches the scribed line.
Glass Condensation Flask (GCF400).
The GCF400 is a wide-mouth flask which facilitates removal of condensed solvent. A
rubber Flask Cover (FC400) fits over the top, and tubing attaches to this by means of
fittings pushed into molded ports on the rubber cover. This forms the vacuum connec-
tion. An insulating foam cover fits over the flask to seal in the cold and seal out atmos-
pheric condensation from the refrigerated chamber.
Place a clean, dry Glass Condensation Flask into the stainless steel chamber. Fit the
insulating cover (white foam ring) over the flask. Seal flask mouth with the black rubber
Flask Cover. Press down flask and insulating cover so that the level of CryoCool
® rises
around the flask, and so that the flask, its cover, and insulation are seated to operating
position. This will fully seal the chamber. Withdraw the flask again and verify that the
level of CryoCool came to within about a half-inch (12–15 mm) from the top (shoulder)
of the flask. If the level is low, carefully pour more CryoCool into the chamber while
holding down the flask.
Immediately wipe clean any CryoCool that spills onto the rubber chamber seal or Flask
Cover.
Muffler and Optional Trays.
Attach the muffler to the solvent vapor exhaust port on the right side of the Universal
Vacuum System. For applications requiring post-pump gas trapping, attach instead the
optional Post-Trap Assembly (ANT100) or Chemical Trap Kit (DTK120; Figure 2). The
ANT100 is used with either Ammonia Neutralizing Solution (ANS121), which neutral-
ized ammonia vapors and reduces ammonia smell in the laboratory, or NSA300TF
which neutralizes acids. The DTK120 comes with a DC120R Disposable Cartridge for
adsorbing volatile radioactivity and trace organics. It may also be fitted with a DC120A
Disposable Cartridge (available separately) for neutralizing acid vapors.
