Product description 

The Aurosphere 800 silica superparamagnetic beads from Magnostics represent a breakthrough in performance in magnetic separation - the magnetization of these particles is 3-5x higher . This means that bioseparations can be performed in seconds with a high level of efficiency, even in viscous solutions like cell lysates. The Magnostics 800 silica beads are conveniently coated with a dense layer of silica that make them ideal for the separation of nucleic acids from Lysis Buffers used to collect clinical samples.
