Scrubbing the Mixture

Scrubbing the mixture will circulate the mixture through the 70K cold trap, trapping much of the unwanted junk in the lines. If the amount of contamination in the lines is small, say from re-connecting the cold trap, then the cold trap will not have to be cleaned afterward. If, however, you are performing a full scrub, it is a good idea to clean the cold trap afterward.
