BIOL 1208 : BIOL 1208 Final Exam
Document Summary
Laboratory techniques: 20-25 pts: pipets, mohr: designed to transfer a volume by moving the meniscus of the liquid between two gradation marks on the pipette. The gradation markings on the mohr pipette do not go all the way to the tip of the pipette but stop before the pipette begins to narrow: serological: are graduated to deliver (there is no base mark). The appropriate amount of fluid is drawn into the pipette (with the meniscus precisely on the correct mark) and the entire amount is transferred. For example, if you are going to pipette 6. 5 ml using a 10 ml pipette you would fill the pipette to the 3. 5 ml mark: volumetric: volumetric, or transfer, pipettes are designed to deliver a single precise volume. The volume of the pipette is indicated near the top of the pipette (i. e. , 5 ml).
