6 sty 2019 · Pipets. – Pipets permit the transfer of accurately known volumes from one container to another. – Common types are shown in Figure (1), and information concerning their use is given in Table (1). – A volumetric, or transfer, pipet (Figure 1a) delivers a single, fixed volume between 0.5 and 200 mL.
14 cze 2023 · Calculate the average of the test results by dividing total by the number of tests; Determine the accuracy of the pipette using the formula A= 100* Vavg /V0, where A is the accuracy, Vavg is the calculated volume, V0 is the theoretical volume to be dispensed.
Use a graduated pipet when a wide range of volumes need to be measured. There are two main types of graduated pipets: Mohr pipet The Mohr pipet has graduations that end before the tip. It is calibrated “to deliver”, meaning that the last volume of liquid should remain in the tip. “To deliver” pipets are indicated with TD on the label.
29 sty 2024 · A pipette is a vital laboratory instrument utilized in fields like chemistry, biology, and medicine to accurately transfer measured liquid volumes between containers. It serves as a crucial tool for precise experimentation and research, particularly in dispensing various media.
There are uncertainty values associated with all types of apparatus in the laboratory. However, for this lesson we will only consider pipettes, volumetric flasks and burettes as they make up the majority of the types of apparatus that we use on a regular basis. Percentage Uncertainty.
