Need bac water, quick!

Really appreciate the recommendations. I think I'll stick with Easy Touch. I'm worried about the needles breaking, especially since I inject where I can't always see what I'm doing. I went with a shorter length because the longer ones were making my stomach itchy. Thanks again!
 
I only have Easy Touch syringes, and both sizes. I went to pin myself a couple of weeks ago, but the plunger got stuck or something.
 
For those of you using bacteriostatic water for your peptides, have you tried acetic acid? Studies show it prolongs the shelf life for certain peptides.
 
That's an interesting idea, @Claudia_Way. I'd be worried about messing up the pH balance though. Do you have to use a specific concentration of acetic acid? I'd be interested in seeing those studies, if you have them handy.
 
Quick question for folks who've done this before - does the final mixed vial need pH testing, or should the bac and AA mixture already be at the right level before peptide goes in?
 
with 4mm filters air purging pushes maybe 1/3 to 2/3 of liquid through. tests show most peptide makes it into the final vial — what stays behind is negligible. 13mm filters i'll use bac purging instead. one approach per filter size works best.
