Hanna curvette cleaning?

[Mekanic]

Question for my chemsperts (see what I did there?) How do you go about cleaning glass curvettes? (or are the hanna;s quartz?) either way, how does thou clean the inside of them.

I know in lab chem a different cleaning solution is needed based on the deposits in the vial.

I have the 714 and just ordered the alk, wondering my best cleaning method for them.

A bit of vinegar and some swirling might be useful from time to time.

I keep vinegar and RODI in a spray bottle and use it when cleaning.

Crusinjimbo, do you mix the vinegar and RODI in one bottle or do you use them at the same time only in separate bottles?

I rinse them with tap water and then several times with ro water within a few minutes of each use to prevent staining.

I rinse mine with ro/di after each use. every so often I soak them overnight in vinegar.

I use a tiny bottle brush cleaner to clean the inside. I think it was used to clean out baby sipy cups or something

I rince with tap then again with RO/DI. I them fill with RO/DI and store full so no dry film will form. I also due this with my red Sea bottles.

That's what we do with our lab ware in my lab. Lot's of tap to get it clean and then DI to rinse the tap away. It's the DI rinse at the end that is important. That keeps it from drying with any streaks. Be sure to get the outside too.

The cuvettes are certainly not quartz. Quartz cuvettes are very expensive.

The other thing to watch out for on any cuvette for any instrument is fingerprints. It is really easy to mess up a spectrophotometer with a fingerprint. Always handle the cuvette from the sides that the light doesn't pass through.

I mix vin and RODI (75%|25%) and use it on darn near anything that needs cleaning with a thorough RODI rinse. I also cap the rinsed corvettes while wet.
