Burets   |
Buret At first glance, a buret looks like a graduated cylinder. However, the buret has something the graduated cylinder does not: a mechanism for slowly dispensing the liquid. Because of this mechanism, a buret is often used in a reaction called a titration. Titrations are reactions where one chemical solution is added to another until a stopping point is reached. At that point, an exact amount of solution in the buret used is known by subtracting the final volume from the initial volume.

Pipets   |
Pipet and Bulb A pipet and bulb are much like a medicine dropper but upsized. The purpose of a pipet is also the same as a medicine dropper: the transfer of solutions. Pipets can be graduated, like a graduated cylinder, or they can have only one specific mark at a certain volume like a volumetric flask. The bulb is squeezed and put on top of the pipet, then allowed to draw the liquid into the pipet. With larger pipets, the bulb may need to be removed, squeezed and used to draw again to fill the pipet. NEVER fill pipets by mouth. Find out more about pipets at: How to use a pipets at: |
