Sample containers should be filled by how much?

Sample containers should be filled by how much?

• A. Two thirds or all the way
• B. Half
• C. One third
• D. Full to the brim

Answer: (A)

Filling sample containers at about two-thirds of their capacity (or to the top when the method requires it) provides the right balance between having enough material for all planned analyses and allowing safe, reliable sealing and handling. Two-thirds leaves space for sealing the container, mixing if needed, and potential aliquots or retests, while still giving you a sufficient volume for the analytical steps. Filling only half or one-third yields too little material for all required tests and possible repeats, and filling to the brim can increase the risk of spills, leaks, or contamination during transport. Some methods specify filling to the top, but the common default is two-thirds to accommodate both volume needs and practical handling.
