@fayorks,
I did some blood protein work years ago and I recall we would always pour the agar powder into the "broth" in an Erlenmyer an just keep it from clumping. Then when we autoclaved it the agar went into a colloidal soln.

THEN, the important part was to make the plates and store them upside down after setting down to 40 C(I think it was that high)
