How to clean laboratory glassware properly in 10 steps

Cleaning laboratory glassware is crucial to ensure accurate and reliable experimental results. Here’s a guideline on how to clean laboratory glassware properly in 10 steps.

Materials needed for cleaning glassware

  • Mild detergent or laboratory glassware cleaning solution
  • Deionized water or distilled water
  • Bottlebrush or test tube brush
  • Plastic or rubber gloves
  • Soft brushes or scrubbers
  • Towels or lint-free paper towels
  • Compressed air or nitrogen

Laboratory glassware cleaning procedure steps

  • Put on protective gloves to avoid direct contact with chemicals or contaminated substances.
  • Rinse the glassware with tap water to remove any initial contaminants.
  • If the glassware has stubborn residues, consider soaking it in a mild detergent solution. Allow it to soak for 10 to 15 minutes.
  • Use a brush or scrubber to clean the inside and outside of the glassware. For narrow tubes or vessels, use a test tube brush.
    • Avoid abrasive materials that may scratch the glass.
  • Rinse the glassware thoroughly with deionized or distilled water to remove any soap or detergent residues.
  • For specific contaminants, use specialized cleaning agents or solvents as recommended for the particular substance.
  • Allow the glassware to air dry on a clean surface. Be careful not to introduce new contaminants during the drying process.
  • Inspect the glassware visually to ensure that it is clean and free from residues. Check for any cracks or damages that could compromise its integrity.
  • If available, use compressed air or nitrogen to blow water out of narrow tubes or other hard-to-reach places, ensuring complete drying.
  • Once thoroughly cleaned and dried, store glassware in a clean and dust-free environment.
