Re: [DIYbio] diy magnetic plate for DNA purification?

Yeah, I know of the commercial ones. We got 2, but they're $300 or so.
Pricing the small 0.25 diameter magnets, you can get 100 for $32 from
unitednuclear. I was thinking of placing them on a used pipette tip
rack. That is, unless the magnets the companies use for their stands
are special for magnetic beads? Anyone know?
