ABSTRACT:
Preparations of particles having a glass surface, wherein more than 75% by weight of these particles have a particle size between 0.5 μm and 15 μm and a glass surface which contains between 2 and 6 mole % zinc oxide, have proven to be particularly advantageous in processes for the purification of nucleic acids. This in particular results in an increased nucleic acid yield.
