New better magnets

I took some hard drives apart today and usurped the magnets inside. These magnets are very powerful and pull the iron beads to the side quite quickly (full removal within 2 seconds). You can even pull the beads completely out of the liquid (good for aspirating the entire wash volume and not disturbing beads!!!) Be careful with them though, they WILL pinch fingers and it DOES hurt. Eventually, I may affix them to an 80 well rack for easier use, or you are welcome to.

This is quite a wonderful discovery Brad! It will definitely shorten the time for separating beads and reduce chance of accidentally pulling up beads with pipettor.
