Hi all. Of course when we're extremely short-handed we have a problem with
the hemo. Thought I'd ask for help before my brain goes kaput. We make our
own Mayer's hemo & yesterday it was muddy & too purple. We tried a couple of
batches - all with same results. The 1 new lot that we have is the aluminum
ammonium sulfate. I think that is the culprit. Does this make sense to
anyone else? I'm open to other ideas, too.
