What is everyone using to test their glassware for detergent residue? Is there a ready to use solution or not?
CAP Checklist... Glassware Cleaning Phase II There are appropriate documented procedures for handling and cleaning glassware, including methods for testing for detergent removal. NOTE: Special instructions for micropipettes, cuvets, acid washing, etc. must be included. A simple procedure to check for detergent residue uses bromcresol purple (0.1 g bromcresol purple in 50 mL ethyl alcohol). Pipette approximately 5 cm (2 inches) distilled water into a representative, washed, glassware item. Add two to three drops bromcresol solution. A purple color reveals residual detergent. A yellow color indicates satisfactory rinsing. Thanks!
