Wetting instructions for plastic bed supports
Follow these instructions to wet top and bottom plastic bed supports before packing
the column.
1
Before using new plastic bed supports, wet the bed supports in 20% v/v 1-propanol
for at least 12 hours in an appropriate container. Make sure that the bed supports
are submerged below the surface of the solution by placing a weight on them.

Rinse the bed supports in 20% ethanol and keep them soaked in 20% ethanol until
they are mounted in the column.

Place the wetted bottom bed support in a new snap ring. Fit the bed support and
snap ring assembly onto the bottom distributor and mount on to the column as de-
scribed in this Operating Instruction.
