Mastering Meniscus Reading: A Comprehensive Guide To Interpreting Fluid Levels
To read a meniscus, observe its shape: concave (curves upward) or convex (curves downward). Liquid type and surface tension influence the shape. Cohesion (attraction between liquid molecules) and adhesion (attraction to the container) determine curvature. A concave meniscus indicates a liquid that “wets” the container (low adhesion), while a convex meniscus suggests poor wetting (high…
