Questions about making bac water

Hey, I want to make bac water and Ive got some quetions. For now I bought USP/ph.eur/BP 99,95+ % benzyl alcohol.

Im gonna buy one of these sterile water for injection: Ampuwa, BBraunAqua, Noridem

And one of these vials: option1, option2

for filtering the benzyl alcohol (coudlnt find sterile ones on amazon): Sterile syringe filter - PTFE hydrophilic 25mm 0.22um 1pc.

My questions are:
1. Should I store benzyl alcohol at room temp or in the fridge?
2. Which vials would you suggest me to buy from the 2 links I provided as they have different stopper coatings
3. I have the option to either buy 10ml vials or 20ml vials, what would you suggest me? I need 30ml bac water monthly, but was thinking the smaller the vial, the safer as it will be consumed the fastest.
4. The benzyl alcohol is 100ml and came in a bottle. 100ml will last me many years. I suppose opening the bottle over and over again to draw with the filtered syringe wouldnt be good, so I should inject the benzyl alcohol in a vial. Should I buy a separate 100ml vial to inject the benzyl alc in it, or use 10x10ml (or 5x20ml) vials, which I will also use for storing bac water, and inject the 100ml benzyl alcohol in multiple 10ml/20ml vials?
 
Posted that link kinda hoping someone had an even better deal, but does illustrate what a more reasonable price should be for even highest grade BAC water. :)

I mix a whole gallon up at a time. Keep it in the fridge. Draw and filter into sterile pre sealed vial as needed. I use distilled water. I keep my shit in the fridge as I reconstitute my gh with it. Sounds like you are way overthinking it man. Just mix your BA and water together. Draw and filter into your sterile vial.

Does anyone know which vials would work best for storing benzyl alcohol and bac water? PTFE or butyl rubber stoppers?
 
ptfe is more "chemically resistant "
Do you know if I have to filter out pharma benzyl alcohol too (99,95+%)

13 syringe filters cost 30€ + 10€ shipping, more than the benzyl alc + water for injection

my benzyl alc bottle is 100ml
I will draw with 10 syringes and inject the benzyl alc in 10 different 10ml vials
or should I use 1x100ml syringe and only draw once?

i would filter your ba for sure, just to remove ANY potential issues,, 99.5% whats in the other % in there , ,

Some people don't filter it at all. I don't filter the BA separately, but I filter the final product.

Same. I mix first. Then filter the mix into my sterile vial.
Do you guys think the benzyl alcohol will be ok for many years?

I will inject 100ml benzyl alcohol spread out in 10ml vials so total of 10 vials. 1 vial will last me 2-3 years. So 20-30 years worth of benzyl alcohol lol. Will it stay ok for that many years in the same vial even after puncturing?

It's so cheap dude. No reason to have a punctured vial of BAC for over a year. But yeah a sealed vial is probably good for a few years.

the bac water vials will last me only 10 days each, but I need so little benzyl alcohol that 100ml will last me at least 20 years.
Should I just buy new benzyl alcohol every 5 years then? I was planning on spreading the 100ml benzyl alcohol in 10x10ml vials, but if it wont be good for that long I guess only filling 2 vials would be enough as 20ml lasts me 5-6 years

Your Wayyy overthinking this bac water , mix/use/store correctly, rinse and repeat as necessary,,

BAC is so inexpensive and easy to acquire, a 5-year stock isn't remotely necessary.

Agree with Ateam, you might be having a little OCD moment here. It will pass.
