Hot Plate Stirrer, was Re: question about VDB

I have a Corning PC-320 hot-plate stirrer with the magnetic bas that
spins these little slugs around. It is great for a wide range of
mixing operations.

Bought mine on ebay in EX+ condition for much less than $100, and
purchsed a pack of the magnetic slugs for about $10.
