they are on ebay regularly. use search terms that will bring them up. i got a nice stir plate with bars for $35 shipped. it has no heat, and in new condition but very slightly used a time or two. it looks like a toy in the pic, not like real lab gear. real used lab plates with heat get $50-150, depending... vary all over the place. for just the bars, try pasting in and searching on:
mag* +stir* +(bar*,teflon,spinner*) i just tried that and there's plenty. -----Original Message----- From: Linda [mailto:[email protected]] Sent: Sunday, November 11, 2007 9:52 AM To: [email protected] Subject: CS>Home made generator Thanks for the information on the measurements for silver. I would like to have a generator that makes the cs by itself but I can't afford one. I have a great brother who knows how to do all that stuff though so he is going to build the generating part for me. I know how to make a magnetic stirrer but I need a teflon coated stir bar. These things were all over the place when I was working as a laboratory tech; nobody ever gave them a thought, but since I retired I found out just how expensive they are. Anyone know where I can get one at a reasonable price? $90 for 12 is too much since I only need one. Didn't find any on Ebay. Or maybe there is something else I can use for the stir bar......? Linda
