The meniscus in a graduated cylinder forms as a result of the difference in the. Web in a graduated cylinder, the meniscus forms due to the cohesive forces between liquid molecules and the adhesive forces between the liquid and the cylinder’s inner surface. Your eye should be level with the top of the liquid. We take a look at how to choose the correct graduated cylinder, what is a meniscus and how to properly read the graduated cylinder and get accurate results. If the meniscus is convex, take your measurement at the highest point of the curve.
To read a meniscus, you first need to see what type of meniscus your liquid forms. Common uses[edit] graduated cylinders are often used to measure the volume of a liquid. Web when a tube of a narrow bore, often called a capillary tube, is dipped into a liquid and the liquid wets the tube (with zero contact angle), the liquid surface inside the tube forms a concave meniscus, which is a virtually spherical surface having the same radius, r, as the inside of the tube. Web a graduated cylinder, or measuring cylinder, is used mainly in laboratories requiring moderately precise volume measurements.
Your eye should be level with the top of the liquid. The meniscus in a graduated cylinder forms as a result of the difference in the. Web a graduated cylinder is meant to be read with the surface of the liquid at eye level, where the center of the meniscus shows the measurement line.
