4 Getting started
4.8 Preparing the column for a run
Cleaning
GE Healthcare recommends that the outside of the column is cleaned with, for example
water and/or 20% (v/v) ethanol to remove any surface residues acquired during removal
from the packaging.
Before use, carefully pump 1.0 M NaOH into the column, empty, and then pump a
washing liquid, for example water, through the column to ensure that all inner surfaces
are clean.
With exception to plastic parts, all parts of AxiChrom 50, 70 and 100 may be autoclaved
if required.
