Cleaning the purge vessel after use will help to prevent clogging of the frits or
contamination of the glassware. Periodically, it is a good idea to clean the
glassware thoroughly in a laboratory detergent to remove any material that cannot
be rinsed from the purge vessel. Turn off the inert gas supply and remove the 1/4"
to 1/8" reducing unions on the gas inlet and the outlet of the purge vessel. Remove
the needle valve from the purge vessel and the three stopcocks. Soak the purge
vessel, needle valves and stopcocks in warm detergent for several hours. Use an
ultrasonic cleaner to assist in cleaning. Rinse the purge vessel thoroughly in
deionized water and allow to air dry before re-assembling the purge vessel.
