Storing a used filter plate

Proceed as follows when you want to store the filter plate:
1 Clean the filter plate mechanically.
2 Clean the filter plate chemically.
3 Rinse the filter plate under running tap water.
4 Protect the filter plate against drying out by storing it in the Filter-
CL cleaning container or in a closed plastic bag.
NOTE
Protect the filter plate from drying out. If the filter plate dries out,
it becomes hydrophobic, blocked and no more sample solution
can go through.
If the filter plate has dried out anyway, proceed as follows:
Submerse the filter plate in a 30 % ethanol or spirit solution for about
60 seconds (approx. 5 l solution are required for the filter plate to be
completely submersed in the Filter-CL cleaning container).
This reduces the surface tension of the filter plate, and the flow rate
should come up to the usual value. For fault-free operation, the filter
