Changing the filter membrane
Labeling the removed filter membrane
Label the filter membrane that you just removed using a clear & logical
system.
An example of labeling filter membranes:
xyz-1-A-005
xyz
Current sample series, component designation
1
Number of membranes created for a measurement series
A
If several equivalent rinsing operations are to be performed for a
component, A, B, C and Z are used for creating a random sample.
005
Membrane filtration fineness, 5 µm
020
Membrane filtration fineness, 20 µm
100
Membrane filtration fineness, 100 µm
