What is the use of triangular file in laboratory apparatus?

Answer:

Most commonly it's used to score small diameter glass tubing before breaking it so that it will break cleanly instead of shattering.

Don't attempt to saw through the tubing with the file. If it won't break cleanly with a light score, you'll need to use a different technique such as scribing followed by thermal shock.
