Hi, I've got 3 sort of freaky questions. They have to do with solution sterility and medium-term storage of a chemical intended for IM injection:
1) I would like to store my stuff as a solution in a completely clean environment for at least a couple of months. The problem is I can't get sterilized vials of any sort. Can't get benzyl alcohol vials. The only thing I can get are empty vials of dog vaccines taken from a veterinarian. These are clean and one-use vials so no worries of getting dog blood into my body, but we all know that vaccines are basically lab-treated viruses, right? So my question is, is it safe to rinse repeatedly these vials (without opening them) with something like water with 0.001% bleach in order to get the most of the remaining vaccine powder, inject my solution into it with a 0.25 micron-filter, and not suffer from some kind of canine disease?
2) If this is not recommended, an alternative would be just passing the solution after the micron filtering to another syringe, just cap it, and extract whatever amount is necessary from it afterwards. A syringe isn't hermetic of course, but I have heard of people storing K this way for months without suffering degradation or muscle abscesses.
3) What would be better as a preservative, bi-distilled water mixed with 0.9% ethyl alcohol (can't get benzyl), or distilled water with 0.9% sodium chloride=
