N Test - Distilled Water

A lot of the guidance says to test N at home in "distilled water" - can normal water or jug-filtered water work or is "distilled water" something different altogether?

that is the purity test you are talking about. If you want to just test what the substance you have is, you just use a urine test kit that tests for barbiturates.
and before anyone posts BS that urine test kits aren't reliable, here's a good way of thinking about it.
you have bought a substance that is meant to be a barbiturate, you buy a kit that tests for barbiturates, you test the substance and it shows up instantly its a barbiturate despite being diluted in water. thats not a COINCIDENCE!!!!!!!!
I think in theory any water would work. It just tests for barbiturates within a certain particles / ml threshold. Personally, I would use distilled water just to be safe though, those jugs aren't that expensive. If you do complete the tests, please post your results so the community can benefit.
Thanks both - bit confused - the Exit "Qualitative" Test Kit I planned to use says to test in distilled water - are you saying therefore that's a "purity" test and somehow different from the urine test kits you can get? I thought they both just told you what the substance was and for anything else you'd have to send a sample away?

Doing a single test strip is a qualitative test, are there barbiturates in your N, yes or no. But you won't know the strength.
When you do the water jug test, you are testing the purity. You'll need a high level of N in the substance to still get a positive test after the second jug, because it is so diluted. It's not an exact science that you can point to x% pentobarbital, but you can have assurance that there is strong amounts of N in the liquid, implying a high %.
Oh I see, so doing the Exit dip test for 5 seconds is the qualitative test and involves putting the contents of the syringe into a small amount of distilled water (e.g. 50ml), dipping in and waiting 5 mins for the result to see if it contains barbiturates.
Then if you want to go a step further and do the "purity test" you basically used the water jugs containing more distilled water.

basically the distilled water test is a 'poor' mans way of getting lab results. Because you keep diluting the N over a series of bottles, it means the more bottles that show a positive test the higher the purity of N will be.
I think it would be more use if you have powdered N, as a sealed veterinary bottle will be the exact purity its meant to be.

I used normal water. it isn't going to show up as barbiturates if it doesn't contain them, no matter what water it is!!!! It will be more important with the other test as you are testing for purity.
That's really helpful thank you. One final question sorry - the sample from the syringe is always diluted in water before testing right? Part of the PPH wording is confusing and says "Saturate the absorbent tip of the dip card with the veterninary liquid you have removed from the syringe and replace the plastic cap" as if it goes straight on without being put into water?
I did this.......
withdraw the N from the bottle and place it into the water, then stir( I used 0.3ml in 50ml of water , there may be variations on that amount)
then follow the instructions on the test strip. for example, mine said place in the liquid for 10-15 secs not above a certain marker on the card.
I actually wondered if people were testing it the way you describe. i imagine either way as long as it shows positive for BAR your ok!!!

No, there is only a video on youtube using the powder. My recommendation would be to replicate the video by using the same concentration per ml of N in liquid form. This might require some calculations. Good luck man, please keep us posted on the results of your tests.
I suppose in theory less N and less water should have the same outcome, i don't know the reason for using the big bottles and the amount of N recommended. Unless there is some science behind it???? i used 3ml when i tested mine with a qualitative test. I don't think unopened, sealed from a veterinary source N needs to be tested for purity. Its mainly for testing powder N as this was known to be less potent and you would need to know the info more, so you knew you were taking the right amount

I haven't done it yet. I have plans to do it once I move out and am in a position to order N. I would give it a go. Please post your results once you've completed the test.
The initial single strip/qualitative test was good thanks both - are your plans to both do a follow-up quantitative test either a) home distilled water or b) EC?

I'm not testing mine with the water jug test, as i know a sealed bottle of veterinary nembutal with a tamper proof seal will be EXACTLY what it says in the bottle, you don't get FAKE nembutal in a sealed, tamper proof bottle i can GUARENTEE that!! I will show your even better proof of its legitimacy, when ver soon i won't be on here anymore because drank it!!!
