If they are providing you with a pH of the wort, then most likely it was soured pre-boil. If that is the case then simply pitch at a rate according to the OG.
If it was soured post-boil (which I highly doubt), then your fermenters do not need to be segregated from your "normal" fermenters providing they are glass and not plastic. Glass carboys can easily be cleaned with hot water and PBW soak, followed by several hot water rinses and finally a starsan treatment for sanitation prior to filling with fresh new wort.
Most importantly though, any plastic or rubber equipment pieces that come in contact with the post-boiled soured wort/beer should be kept separate. Things like auto-siphon parts, transfer hoses, airlock, stoppers, wine theif, etc. so they are not contaminating other normal beers.
But as stated earlier, I would bet that the wort was soured pre-boil and you will have no problems treating this as a normal brew. If pitching yeast be sure to aerate the wort to ensure a healthy fermentation for your yeast.
Good luck and keep us posted with what you decide to do.
