Volumetric Pipette Meniscus. a liquid’s meniscus is the curvature of the liquid surface in a narrow container. To read a meniscus, you first need to see what type of meniscus your liquid forms. pipettes are used to measure small quantities of volume, usually up to 10 milliliters. The level of concave (downward curving) liquid. when the bottom of the meniscus coincides with the calibration mark, your pipet contains a precisely measured volume, as in the image at the left. if the liquid molecules are attracted more strongly by the glass wall (adhesion) than by their own kind (cohesion), the meniscus is curved downwards, or. when you read a scale on the side of a container with a meniscus, such as a graduated cylinder or volumetric flask, it's important that the measurement accounts for the meniscus. if the liquid forms a curve, how are you expected to make an accurate measurement of the amount of liquid in a container? They work on the principle of. If the meniscus is a concave meniscus, read at the lowest level of the curve. use the density for your temperature to calculate the volume of water delivered by your pipette in each determination, the mean volume, the standard deviation, and the 50% and 95% confidence limits for the mean. Measure so that the line you are reading is even with the center of the meniscus.
