Which of the following is a common glassware item found in chemical and biological production laboratories?

• A. Beaker
• B. Ring Stand
• C. Thermometer
• D. Pipette

Answer: (A)

In laboratory work, the beaker stands out as a versatile container used for holding, mixing, and often heating liquids. Its wide mouth and straight sides make it ideal for quick estimates, pouring, and general-purpose tasks that occur in many chemical and biological production workflows. The ring stand is hardware used to support glassware, not a container. A thermometer is a measuring device for temperature, not something you use to hold or mix liquids. A pipette transfers precise small volumes, which is important but focuses on transfer rather than serving as the general-purpose glass container. For everyday, common glassware across these labs, the beaker is the best fit.
