Sponges are an alternate, nevertheless the sponge may perhaps dry tissues and small fragments of tissue may well dry, harden, and stick with the sponge.

For all processing aids, make certain the papers and sponges are moist While using the fixative of option.
If that cassette was entirely crammed there would be no room for an appropriate fluid penetration. The tissue is currently All set for fixation.
