Which method is typically used to sterilize glassware in a laboratory setting?

• A. Heating it to high temperatures
• B. Soaking in detergent, rinsing in solvent, rinsing in distilled water
• C. Wiping with alcohol
• D. Using ultraviolet light

Answer: (B)

The typical method used to sterilize glassware in a laboratory setting is by heating it to high temperatures. This process, often referred to as dry heat sterilization, effectively kills bacteria, viruses, and spores on the glassware by denaturing their proteins and disrupting cellular processes. High temperatures ensure that any contaminants present on the surfaces of the glassware are eradicated, making it safe for subsequent use in experiments. In contrast, soaking in detergent and rinsing is more focused on cleaning rather than sterilization, as it may not eliminate all microbial life. Wiping with alcohol can decontaminate surfaces but may not provide the level of sterilization needed for laboratory work. Using ultraviolet light is effective for disinfection in some contexts but not as reliable for thorough sterilization of glassware when compared to traditional methods like high-temperature heating.
