3.4 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 at a ﬂow rate that is 50% of the recommended ﬂow

rate (see Table 1). This will prevent microbial growth. Store the

column in a safe place at room temperature or 4°C. Never allow

the column to freeze.
