Bacteriostatic Water usually has 0.9% ba. So 20ml has .18 ml and 30ml has .27. Math is: 20x.009 and 30x.009. You will have to use insulin syringe and .18 ml is simply 18 marks on syringe. Hope this helps.

Making bac H20

Thanks for your reply bro, I really just wanted to make sure that my math was correct.
Now for 1 more Q', I was gna filter ba w .22 micron filter into still sealed 20ML sterile water bottle.
Do you think it's necessary? (Can't hurt) and won't be too time consuming.
