formalin
This term refers specifically to the aqueous solution of formaldehyde rather than the pure gas. In laboratory and medical settings, it is used as a fixative to preserve the structural integrity of tissues, preventing autolysis and putrefaction.
Because it is a chemical solution, it is treated as a mass noun. It is never used in the plural form to describe multiple containers or batches of the liquid; instead, quantifiers such as "amount of" or "volume of" are used.
Ý nghĩa
