What do the initials TC stand for in laboratory measurements?

In laboratory measurements, the initials TC stand for "To Contain." This designation indicates that a container or measuring device is calibrated to hold a specific volume of liquid, but does not account for the liquid that may remain on the inside walls of the container when it is poured out. This is particularly important in laboratory settings where precise volume measurements are crucial for accurate testing and analyses.

Understanding the meaning of TC is vital for laboratory analysts, as it affects how one interprets the results of volumetric measurements. The term emphasizes the importance of proper dispensing techniques to ensure the accuracy of liquid volumes used in experiments. This knowledge helps in maintaining consistency and reliability in test results, which is fundamental in drinking water analysis and compliance with regulatory standards.
