I absolutely despise the nitrate test. I always lose half the test water by the time I'm done shaking it.
Good point. I guess rubber stoppers would be the way to go.I wouldn't use cork, or that foam stuff they sometimes use, since it would retain test solution in the open cells of the material. I'm going to check around locally to see if places have them.
@ $.03 a piece I'll send you a quarter for 8 + shipping to me.If I am able to find a bunch of the right sized stoppers locally, would anyone be interested in a bulk buy? I could buy a contractor box (if available), and mail them at cost.
Edit to add: I have found a place online where a bag of 1000 stoppers is about $30+shipping. That's waaaay more stoppers than I will ever need, so if anyone is interested, let me know.

I would love a few of these! Please remember to add to the actual cost something extra for your time and the hassle (and expense) of packaging and mailing!

I have to double check the size of the tubes, I think they will take 00 sized stoppers, but want to make certain before ordering 1000 of them
I've also seen other "plugs" that can go in the tops of the tubes, plastic ones vs rubber stoppers. After looking at the rubber stoppers, I noticed they were labelled as having "low sulfur content", which makes me wonder what, if any, impact that would have on the test. I think I might go for the plastic plugs instead, since they will most likely be less reactive.

My 25 cent quip was more of a joke. I'm interested in a half-dozen for a couple bucks plus shipping. I guess if you can get enough people together that you can recoup the $30, regardless of how many extra tubes you have left, and break even on shipping, I'm good with that. Hey you'll end up with hundreds of test tubes you can sell on ebay with your costs already covered.
I will pass on your concerns with the coloration for the cards so the research and development teams note your comments. Make sure that when you are testing you hold the test tube directly against the white background of the color card as this may help in allowing you to match the color in the tube closest to the color on the card.

Honestly i wish some one would come up with a digital read out testing device where you can just put in a small sample in a collection tube and have a computer do the work.
