acetic acid

[drewdwn]

I know that IGF needs to be mixed with acetic acid (AA). My question is can any AA work for this? I see a number of places that sell it just not sure witch to use.

You can use standardized 5% distilled white vinegar and dilute in with sterile water using a whatman filter

RedBaron has a post on it .. search for it

I found Acetic acid from a science lad supply company with 6%, would this work?

^^ yes, but your dilution mathematics will have to be adjusted. You need a very specific amt of AA with sterile water to make just the right pH

perfect dilution, you need 0.6% for AA
