3.1 EMPTYING THE GLASS CONDENSATION FLASK
During system operation, solvent vapors from the SpeedVac or other attached instru-
ment will collect in the glass condensation flask. The flask must be regularly emptied to
keep the entire system operating at peak efficiency. If the flask is not maintained, it may
become so full that sample drying rate is adversely affected. Another consequence of a
full vessel is that solvent vapors are more likely to contaminate the oil-sealed vacuum
pump bypass the trap and be released to the atmosphere.
Empty the glass flask before it is half full. Often it is convenient and good practice to
change the flask at the end of the workday or workweek, no matter the depth of fill. For
aggressive solvents, you may wish to remove the flask at the end of each run for maxi-
mum protection of the system components.
CAUTION: The UVS400 and UVS400A reach low operating temperatures that can
cause severe damage to unprotected skin. Wear protective gloves
and clothing when removing glass flasks.
To remove the GCF400 for cleaning, bleed the system back to atmospheric pressure.
Remove rubber Flask Cover from flask, leaving tubing attached to cover. Withdraw the
flask partially from the chamber and allow CryoCool to drain briefly. Fully remove flask
and insulating foam ring. Avoid thermal shock by placing the flask on several thickness-
es of absorbent paper toweling and allow to come to room temperature. Insert a spare
GCF400, which is clean and dry, into the chamber. Cover with insulating foam ring, and
seal with rubber Flask Cover. Make sure rubber cover is seated firmly for a good vacu-
um seal. This easy system maintenance can be done in a matter of minutes; the power
(refrigeration) switch need not be shut off during this process. When the used flask has
defrosted, dispose of contents in an environmentally responsible manner. Clean and dry
flask for next use.
IMPORTANT: Check the Glass Condensation Flask before each run and
replace with clean flask if approaching half full. Immediately wipe
dry any CryoCool
® Heat Transfer Fluid that falls on the rubber
seal. Be sure Flask Cover is seated firmly on the flask.
NOTE: Collected solvents may be purified for reuse or disposed of safely
according to applicable regulations.
If working with radioactive samples, test condensate for presence of
radioactivity. If found to be radioactive, dispose of as radioactive
liquid according to all applicable regulations.
