How to test N and preserve its potency?

[oraldine2]

Hi, I would like to send a sample of N to E.C. but I'm afraid to deteriorate the remaining amount if I do that. The bottles come with a plastic cap to flip off.

- What is expected to be found after flipping off the plastic cap? Is there a metal seal underneath that needs to be open (using some sharp knive or cosmetic scissors) to finally access the rubber and insert the syringe there?
- After the sample is extracted with a syringe and the rubber is not removed, how long the bottle will last without losing its properties?
- Is it better to use a small syringe like one for insuline (max 1ml) and do 2 extractions (E.C. asks for 2ml), or is it better to do a single extraction with a larger syringe(which would create a bigger hole in the rubber) ?
-In case that the N would start deteriorating after doing any of these operations (even though the rubber is not removed), what would be the best way to reseal the bottle ?

Thanks

If the rubber and the metal remains intact, it doesn't deteriorate. The rubber can handle about 50 extractions. It's automatically reseals itself. Potency won't change. Not that I'm aware of anyway. You'll want a smaller syringe. Jsut the standard one like exit international provides. If you look in the PPH there is a video of how to remove it so you can extract a sample
