Cecil:
LMK if you need more PP measured out. For anybody interested, I don't have a gram scale, but I do have an electronic powder measuring scale that measures to 0.1 grain. Since 1 gram is 15.4323584 grains, I rounded it off to 15.4 grains and weighed out that much for Cecil. I have some small plastic screw-top specimen vials that are waterproof, so the 1 gram samples were put in those vials.
Scot,
I only needed a one gram sample for the stock solution so I'm good to go. Thanks a bunch! I'm going to have to get a gram scale at some point. I also want to get a microscope too. I got an awesome book for Christmas that shows me how to set up my own pathology lab. At one time I tested milk in a lab so I have some experience with bacteria cultures. With no vets qualified to test fish in Indiana except at Purdue, I'm going to have to become self sufficient.
