That's not an especially high concentration so I'm surprised it fell out of suspension. Probably didn't add enough acohol. Nuke it or bake it, give it a good shaking and it should suspend again just fine.
i recommended the bb. just did it for some prop that had fallen out of solution. worked perfectly. i know the gear was good because of the 10 bottles, only 2 were effected. if you arent sure of quality then that could be a concern for you.
If there are big chunks at the bottom I would be worried about having really shitty un-sterile gear.
If you do not trust your source I would recommend doing more than simply baking it because baking it will not kill bacteria. To be 100% safe I would add 1% BA to get it sterile and re-filter the gear and place it in a new, sterile vial.
i had a huge crystal ball in mine too. that will melt when heated, wont tell much about sterility. you could do the whatman filter and all that but i cant tell you if it will work if the gear is not sterile. if you havent used the gear before i would be alittle concerned but if that was all the gear i could get, i'd try it out and see what happens. prop is painful for a few days. if the first 2 or 3 shots are hot and painful at day 5 and seem to be getting worse, i'd quit it.
well, id prob do one shot, monitor it and see if any probs arrise, cause i wouldnt want multiple abcesses, not one, but 2 or 3 would be bad. should i order some bb then? also what size filter should i get?
