Glassware care

[billw]

Randy, currently I fill my Hanna cuvettes with DI water when storing in between tests. Do you have a better recommendation?

There is no need to keep ro/di water in the cuvette. I simply rinse mine with a wash bottle filled with ro/di and let it air dry.

What is most critical with the cuvette is that the outside is squeaky clean and dry. Never, ever put a wet cuvette in a Hanna.

The reason to keep it clean is because particles can absorb light making the reading faulty, as you probably already knew. With mine I simply rinsed with ro/di then buffed the outside and inside glass with a paper towel.

I agree there's no need to keep water in them, but it also shouldn't hurt anything.
