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.
