In measurement, "TC" stands for what?

"TC," which stands for "To contain," is a term used in the context of laboratory measurements, specifically regarding glassware such as volumetric flasks and graduated cylinders. When a piece of glassware is labeled as "TC," it indicates that the device is designed to contain a specific volume of liquid when filled to the mark, but it does not account for any liquid that may adhere to the walls after pouring. This means that a TC measurement reflects the intended capacity of the container.

Understanding this term is essential in laboratory practices because it influences how measurements are interpreted. Knowing whether glassware is "To contain" or "To deliver" (which would be labeled as "TD") helps researchers accurately assess the amount of substance being transferred and ensures precision in experimental protocols. This attention to detail is crucial in fields that rely heavily on accurate measurements, such as chemistry and biology.
