3.4 Top-Off Resin
If the top of the resin bed becomes fouled and the above hygiene steps do not restore per-
formance, then a few mm of the bed should be removed and replaced with fresh resin obtain-
able from Bio-Rad. See page 6 for ordering information.
3.5 Storage Conditions
Prior to long-term storage, the column should be cleaned as previously described and
then washed with 3 column volumes of 20% ethanol. This will prevent microbial growth.
Store the column in a safe place at room temperature. Never allow the column to freeze.
