Chemistry in Action - Pipetting

| No Comments | No TrackBacks

As you can easily imagine, precision and accuracy in measuring ingredients for chemistry experiments is incredibly important. Precision being the ability to reproduce a measurement and accuracy meaning how close a measurement is to the true answer. Being off by even a small amount when mixing chemicals can result in some very negative things happening, including an inaccurate result. One of the more precise pieces of glassware utilized when measuring liquids is a volumetric pipette. A volumetric pipette is a long glass tube that is used to transfer a precise amount of liquid from one container to another. Professor Gordon Yee demonstrates how to use a pipette to accurately measure a liquid in today's free Chemistry lecture on Pipetting.
