Any way to thoroughly clean the 10ml bottles after repeated use or do people buy new ones?

Thx

Some vinegar might help remove any deposits. I'd give it a try.

Citric acid is what they sell and suggest to clean them with.

With that said, a soak in vinegar is what I do.

curious if my readings will differ much after cleaning. will update tonight.

It shouldn't much if any..
The first step without the reagent is to essentially establish a baseline zero point.. If that wasn't done and was "fixed" in the checker based on a perfectly clean vial then yes..

Now I'm just assuming that your vials aren't overly clouded,etc...

4 bottles (used for Alk and phosphate) sat in vinegar for hours. Definitely a blue/green tint to the vinegar after 8 hours and bottles clean.

Retest yielded very near results to pre-soak levels (8.7 vs 8.6, .64 vs .68).

I agree that the zeroing phase should handle a bit of tint fairly well, so I'm not all that surprised that the results are similar.

Nice, was just wondering that,, into the vinegar

It's still better to have clean vials. The accuracy probably will tend to be better, I'd guess. The range also will be affected, although that's not an issue here.

Rinsing them after each use with tap water and then ro/di water can keep them from tinting; leaving a drop or two of ro /di water in them when stored helps as it absorbs some of the mineral residue .tinting residue.

RobZilla04 · 11/07/2017, 08:31 AM

I've just used RO/DI to rinse them thoroughly after each use followed by drying with a paper towel inside and out. Ensure the cap is rinsed as well so there is no residue left behind.

Probably not a bad idea to vinegar soak after several tests as an added measure.

tmz · 11/07/2017, 09:27 AM

I find it better to not dry it inside ,leaving a bit of ro/di in a closed vial helps keep it clean inside.

I rinse with tap water, and leave whatever tap water doesn't come out when turned over and shaken in the vial. Then put the cap on loosely. This should keep the water in the vial from evaporating and creating any deposits.

When I want to test again I add a few ml of the water I'm testing to the vial, cap it, shake it, and get as much water out as possible. Then I test. This will ensure the vial is "flushed".

Like that idea bitwise. Gonna have to try that, thanks.

I rinse mine with clear water and let dry and polish with a micro fiber cloth.

rocsec1 · 11/09/2017, 08:47 PM

I rinse them and then turn them upside down to dry
