Care and Maintenance of Laboratory Flasks

Keeping laboratory flasks clean and well-maintained is crucial. It ensures the accuracy of experiments. Use organic solvents like acetone or ethanol to clean filtering flasks and other equipment.

Each type of flask needs its own cleaning method. Volumetric and buret flasks should be rinsed three to four times with deionized water. Always check for cracks or chips before using glassware, as damage can affect results.

Drying flasks correctly is important. Air drying on shelves is best, but if you need to return them quickly, rinse with solvent. Avoid using paper towels or forced air to prevent contamination.

Handling glassware safely is essential. Carry heavy flasks with both hands and heat them slowly to avoid breakage. Follow OSHA guidelines to reduce risks. Proper care and handling can make your equipment last longer.
