Let me actually jump back to the beginning and tell you WHY I was measuring out "stuff" on scales and such. It's come to the point in my project where I need to be growing diatom cultures on agar plates (like I do with bacteria), but first I need to make very specific media to grow them on. The agar media is mixed with a very specific balance of vital minerals and such, and because the ratios were different than our lab usually uses, my professor and I decided it was best that I just start from scratch.
I made several different reagents today, of which I'm going to use 1 milliliter of each later when I make the agar media. Yeah, that's way less than an ounce.
In any case, I should run along and catch up on some other work I was meaning to do before I got caught up in lab!
