I have two sizes of plastic graduates;a 150ml
"graduate" that came from some Unicolor kits I had
used as a kid and 30 ml cups that were used to
dispense medicine.
I know that they weigh 12.9 gms. and 2.3 gms
respectively and factor that in when weighing out
chemistry. Since I have a bunch of each size, I can
weigh out all the components of a given formula and
have them waiting to be added as each one dissolves.
My magnetic mixer, although old and stained, is a
thing of beauty when mixing as I can just walk away
when my glycin or ferric oxalate or whatever, takes a
while to dissolve.
