Staining jars acc. to Schiefferdecker,

made of heavy-walled soda lime glass (pressed glass), for up to 20 individual microscope slides approx. 76x26 mm (10 pairs of slides placed adjacently back-to-back), with lid, dimensions 91x74x49 mm relatively high coefficient of expansion. Due to their material they must not be exposed to rapid temperature changes but have to be heated slowly and also cooled down slowly in order to avoid cracks caused by tensions. more
