Does anybody know where I could find paramagnetic beads with a parameter of about 100 micrometer?

you could try invitrogen http://www.invitrogen.com/site/us/en/home/brands/Dynal.html (i'm not sure about the size of the bead).

Many many sources: Seradyn (Thermo Fisher), Invitrogen (Interfacial Dynamics), Varian (Polymer Labs), EMD (Estapor), Bangs Labs (Polysciences), Spherotech, and others......

We use the Seradyn ones.
Weirdly enough it's actually cheaper to buy a complete kit from Agencourt that contains Seradyn beads (for DNA extraction; Genfind v2.0) than buy the same amount of beads from Seradyn directly..
