Measuring volume in the chemistry laboratory
Webcommon equipment in the chemistry laboratory and to gain an understanding of the role of measurement and precision in using that equipment. Specifically, you will be measuring length, mass, liquid volume, and temperature. Results you obtain will be compared with those of other students in order to show the amount of uncertainty in a measurement. WebNov 4, 2024 · It is a device that allows measuring and transferring small volumes, usually between 1 and 1000 μl. Micropipettes are classified into three groups: P1000 useful for volumes from 200 to 1000 μl, P200 useful for volumes from 20 to 200 μl, and P20 useful for volumes from 0.5 to 20 μl.
