PROCEDURE:

    1. Before proceeding with acid cleaning, glassware should be cleaned with a laboratory grade glassware detergent, washed and rinsed.
        1. Most new glass is slightly alkaline and should be washed before initial use.
    2. Using safety precautions, pour sufficient Hydrochloric Acid 5%, Aqueous into glassware; gently swirl to thoroughly coat all surfaces/sides/edges with the solution.
    3. Repeat this process for all glassware/plasticware to be used in procedures that requires acid cleaning, including bottles, beakers, flasks, Coplin jars, graduated cylinders, stir rods, pipettes, thermometers and lids.
        1. See Procedure Note #1.
    4. Rinse all glassware/plasticware with a minimum of four changes of distilled water, ensuring all surfaces/sides/edges are well rinsed.
        1. It is essential that final rinses are distilled water or chlorine-free water.
        2. Tap water rinses may leave surface contaminates on glassware resulting in potential staining issues.
    5. Dry glassware in a designated area for acid cleaned glassware.

 

PROCEDURE NOTE:

    1. Use fresh Hydrochloric Acid 5%, Aqueous with every batch of glassware acid cleaned. The solution can be reused on multiple pieces of glassware/plasticware acid cleaned at the same time.
