Chapter 16 • In General…… • What is the definition of volume and what is the basic unit? • How do you use a graduate cylinder to measure volume? • What are the instruments used to measure volume? • In order of increasing accuracy, list the instruments that are used to measure volume. • How are micropipettors validated?
Glassware • Calibrated either TC or TD-what does this mean? • What are the tolerances for a volumetric in comparison to a graduated cylinder? • Compare and contrast the use of volumetrics, graduated cylinders, beakers and flasks • What is a serological pipet? • What is a Mohr pipet? • What is a Pasteur pipet?
Micropipetting Devices • Positive displacement vs air displacement
Pipetting of Difficult Solutions • Air displacement micropipettors are not very accurate when dispensing volatile liquids (like acetone) or viscous materials (like protein solutions). • Review Table 16.3
Validation of Micropipettors • Box 5 pages 314-315 • Problems • All
