In order for your buret to perform optimally, it must be properly cleaned.
To clean the buret, use the following procedure:
Rinse with distilled water:
With the stopcock closed, add some distilled water to the buret. Tip and
roll the buret, allowing the water to have contact with all of the inside
surfaces. Open the stopcock and allow the water to drain. If the water drains
without leaving any droplets on the side, repeat the rinse twice more then
move to step two. If droplets remain on the inside surface, wash the buret
with detergent solution, rinse several times with tap water, then rinse
three times with distilled water.
Rinse with solution:
After draining the final distilled water rinse, close the stopcock and
add about 5 mL of the solution to be dispensed from the buret. Again, roll
and tip the buret so the solution has contact with all the inside surfaces.
Open the stopcock and allow the solution to drain. Repeat this twice more.
Discard the solution used in the rinses.
After you are finished with the buret in your experiment, rinse it by filling
it with distilled water and allowing it to drain.
