Hi. I am interested in David's post: I too wished to change to Prills for weighing out PFA because the usual crystaline PFA is such a fine powder that it tends to "float" around, when weighing. ( conforming to Health and Safety recommendations by weighing the latter out in a fume hood.... The powder just went all over the place ;-) Hence "Prills".... i thought that they would be the answer! However, as Prills do not dissolve completely, as David indicated ( crystals dissolve completely), I judged that the additional filtration of the Prill-derived Formalin fixing fluid is another "complication" that is more likely to cause problems (spillage, inappropriate disposal of filters...for eg)
So, I would be very grateful for any thoughts/recommendations on this. NB: Not practicable to use commercial vials as we do a lot of perfusions. Best wishes.
