Hello Forum,

For a while have I been following the routine of cleaning the cups/bottles/tubes of Hannah checkers with osmosis water just after been used. Not only to avoid them to get stained, but mainly to ensure there's no chance of any quemical present on tap water to alter future measurements. However, sometimes I wonder if am I going too far with it and I just could do it easier. I also use osmosis water to clean up the pipettes, spilling some osmosis water on a glass to take some of it to fulfil the pipette so every quemical is going with it when pressing/emptying it. What's your routine ? Do you do it "so difficult" or just let it be/use the water directly from tap?

Thank you,

Best regards.

I rinse with RO water but have an RO faucet on our kitchen sink. I use RO because it doesn't seem to leave spots. Some folks are really picky. I've read of people cleaning them with vinegar after each use. I use 9 cuvetts if I dont make a mistake so mine are getting nothing more than a rinse.

After each test I:
add a cuvette about half full of distilled water, cap, shake, discard. Add another half full distilled water, cap and store it with the checker.
Whatever pipette I used for dispensing sample water is the one I use for filling with distilled, so the pipette gets rinsed too.
This is sufficient to give me consistent results unless there's some special reason I think I need to clean more aggressively, and it only takes like 10mL distilled water after the test.

I see. So, It looks like my guess was right, it's something quite reccomendable to clean with Rodi water. I always use distilled water I bought on my local supermarket in carafe format. That's why It's a bit uneasy to rinse the tubes with the carafes. Though, of course, I'll keep doing it like that, as It seems to be the best way to get propper results. Thank you very much for all your fast and useful replies.

I shake (cuvettes) capped roughly half full of RO/DI and dump (twice), then store filled with RODI <-- only because I read it somewhere and seemed logical.
*one idea I like but never do -- rinse out (inside) with tank water right before taking sample

Rinse twice with RO then store empty. Haven't noticed any issues with this. When I take a sample, I rinse with tank water then fill for the test.

This article shows vial contamination following rinsing.

First rinse is under the faucet with tap water. I have a two-cup container of rodi next to the sink that I then fill the vial with and rinse twice, store dry on a 3d printed holder. After I'm done with the vials, I toss the caps into the rodi container to rinse.

I do the exact same thing you do lol. I don't think its going too far. Good habit as to maintain the cuvette and not stain them

I clean the glass bottles as well as the pipets with tap water, then I have a small 3D printed racks glued to the inside of my reefing kit cabinet which holds each upside down. Pipets take 3 days to dry so I have a few and use a dry rack and a wet rack. The 10ml glass bottles dry in a day and I only have 1 rack with 6 bottles. I wash them all at the same time after tests. This works for me
