After several weeks of tinkering with the design, I got my magnetic stirrer to work! Turns out I was too cheap to pop for a proper magnetic stir rod in the beginning. I was messing about with bits of nails, screws, etc. for stir rods, which would fly off the magnetic point inside the flask. I got a 1 inch true magnetic stir rod and, BAM. Works like a charm.
Anyway, I was wondering: How fast to run the thing? I can get a nice slow roll, or I can get a vortex that makes the tornado in the Wizard of Oz look sick.
Anyone have an opinion or experience with magnetic stirrer speeds and starters?
Thanks as always!
