In order to fill a burette for titration, certain procedures come recommended in the laboratory.

  • The burette should be adjusted such that the opening is below or at the eye level, preferably over a sink.
  • A funnel should be used to add the titrant into the burette.
  • The titrant should be filled to almost to the zero mark on the burette.
  • After filling the burette, the tip should be bled to remove any air bubble that might have been trapped in it and titrant added again to the burette up to the zero mark.

Filling the burette over a sink below or at the eye level with a funnel will limit the chances of the titrant spilling while bleeding it to remove trapped air will limit the error in the titer value after titration.
