In laboratory settings, which equipment is NOT typically classified as volumetric glassware?

Volumetric glassware is specifically designed for precise measurement of volume and is commonly used in analytical chemistry and laboratory settings for conducting experiments that require accurate volume measurements of liquids. This category includes pipets, burets, and volumetric flasks, all of which have been engineered to ensure high precision and minimal error during volume measurement.

Petri dishes, on the other hand, are primarily used for cultivating microorganisms or cell cultures and are not designed to measure volume accurately. They have a flat bottom and open surface that allow for evaporation and growth observation, but they lack the calibrations and specific design features that characterize volumetric glassware. Thus, petri dishes do not fit into the category of equipment that serves the function of measuring liquid volumes and are considered more general laboratory ware rather than specialized volumetric instruments.
