To all: We keep having the same discussion re: special stains. How long can you use them before discarding? I am specifically referring to the stains used in Masson's Trichrome.
We are a research lab and, therefore, don't run the volume that most labs do. We have found, for instance, that we can use the Weigert's Hematoxylin (A&B) more than once, with filtering (even though it is stated it should be made fresh). We also use Bouin's Fix, Biebrich Scarlet and Aniline Blue more than once. Is there a "set rule" when we should discard these solutions (i.e. after 5X use or 1 month)? I would appreciate some feedback from the experts! Thanks!
