Cleaning Blood on Quartz Cuvettes

Q. How can I clean blood off of quartz cuvettes for laboratory cleaning?

A. I recommend using a lukewarm (100F or 40C, definitely not exceeding 130F or 55C) 1% Tergazyme® Enzyme-Active Powdered detergent solution (10 g/L or 1.25 oz/gal) to soak your quartz cuvettes. Rinse thoroughly. Use freshly made up Tergazyme solutions that were made within the last 8 hours. Tergazyme is a protease enzyme detergent that is effective at removing blood stains, as well as any other proteinaceous residue. Do not use it at elevated temperatures (above 130F/55C as mentioned) or you risk denaturing the protease enzyme and setting the blood stains. Use fresh solutions so the enzyme is still active.
