  • What should we know about pipette tips?Servicebio

     · We can use a burette or pipette tip to add the exact amount of liquid chemical amounts to a titration process. The key difference between burette and pipette tip is in the release mechanism. Burette has a stopcock at the bottom while a pipette tip has a dropper like system that releases liquid in the desired amount by lessening the vacuum.
