I do these frequently. The lab requesting the work usually does the fixing but I'm sure they do longer than 5 minutes. They then replace the fixative with 70% ETOH and bring the whole thing to the lab.
I use a tip of a scalpel blade to remove the whole membrane and I process it in a screen cassette or a bx cassette with small holes. I don't like to put anything on top of the membrane that might disturb the cells growing on it.
When embedding I cut the membrane circle in half and embed it standing up with the cut side down. I always use charged slides and have done H&E's and various special stains on the membranes and have never had one lift off. I usually let dry overnite and then put the slides in a drying oven with gentle heat for maybe 15 minutes before staining.
