How should you inspect glassware before use?

• A. Discard all glassware even if intact.
• B. Check for cracks, chips, and cleanliness; inspect joints for fit; discard damaged items.
• C. Only inspect glassware after use.
• D. Sterilize glassware before use.

Answer: (B)

Before using glassware, you want to confirm it’s safe to handle and won’t fail during an experiment. The essential checks are for structural integrity, cleanliness, and proper connections. Look closely for cracks, chips, or any visible damage, especially around rims and joints, because even small flaws can propagate and cause breakage under heat or pressure. Ensure the glassware is clean and free of residues that could contaminate reactions or interfere with measurements. Joints and adapters should fit snugly and form a secure connection; a loose or cracked joint can leak, shatter, or cause loss of vacuum. If you find any damage or heavy dirt, discard the item rather than reuse it. Sterilizing before use is a separate precaution and doesn’t replace inspecting for cracks or ensuring joints fit properly.
