Also be sure to handle and store carefully to prevent any damage or discoloration. 2. Do not store solutions containing substances that may corrode or discolor glass in the cuvette. 3. Do not place the colorimetric dish on a flame or electric stove for heating or baking in a drying oven. 4. When contamination is found inside the colorimetric dish, use a specialized cleaning agent or anhydrous ethanol to clean it in a timely manner. 5. Do not allow the transparent surface of the colorimetric dish to come into contact with hard or dirty objects. When containing the solution, a height of 2/3 of the colorimetric dish is sufficient. If there is any residue on the optical surface, it can be gently absorbed with filter paper first, and then wiped with lens paper or silk. Note: This item ships direct from the manufacturer.
