Hi, All,

Electron Microscope Sciences also has a granular formulation of PFA 
that is not dusty, cat # 12910 , 1kg, --that is what we use ---for 
those who may need "vast quantities" of 4% PFA as someone recently 
mentioned. We found it by accident, as there are other vendors that 
claim their PFA to be granular and yet it is just as dusty as all the 
others, so I didn't put much stock in their description... but this 
time, they were right.
