Canada Balsam is a natural mounting medium obtained from balsam fir trees. It is produced from the resin of the balsam fir tree and its use can be combined with xylene-containing specimens. The optical properties of Canada Balsam are nearly identical to those of glass. Specimens must be dehydrated before using this medium. Permanent slides mounted with Canada Balsam have been stored for over a century.
Canada balsam is used as a stable apolar hydrophobic mounting medium for light microscopy slide preparation, especially when long-term storage is desired. It is mostly applicable for cellular staining.
