I Think there is only grade of Canada balsam! A Quick check shows that fancy labeling and special use (microscope slides) pushes the price up quite a lot!.
It is fairly important that the screw top ( with or without built-in dispensing bulb) is cleaned up after use or you will have to use xylene to break the seal for subsequent use.
Single air bubbles in the deposited balsam layer can “rubbed out” to the lens edge, but these are best avoided by having super clean lens surfaces and contact transfer from a glass rod or similar.
