Experiment 1 Post Lab Questions Choosing between the graduated cylinder and volumetric pipet, which is more accurate? Why? Volumetric pipets are more accurak becawe they are made to hold a speciac volume. 2. Choos ing between the graduated cylinder and volumetric pipet, which is more precise? Why? 3.Volumetric pipets are meant to hold a single, specific volume. This type of pipet is a narrow tube with a " bubble" in its center, a tapered tip for delivery of liquid, and a single graduation mark near the top (opposite the tapered end) of the tube. Volumetric pipets, sometimes called transfer pipets, are the most accurate pipets.
Dec 19, 2017 · Graduated/Serological Pipette: When using this type of pipette, the final volume is found by calculating the difference of the liquid level before and after liquid is dispensed, much like a burette. This is the standard technique for using a graduated pipette: Hold pipette in solution, don’t touch the bottom. Feb 27, 2020 · Graduated cylinders are generally more accurate and precise than laboratory flasks and beakers, but they should not be used to perform volumetric analysis; volumetric glassware, such as a volumetric flask or volumetric pipette, should be used, as it is even more accurate and precise.
