Aurosphere 200 silica, Superparamagnetic beads

Regular price €55.00

Product description 

The Aurosphere 200 silica superparamagnetic beads from Magnostic 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 minutes with a high level of efficiency, even in viscous solutions like cell lysates. The Aurosphere 200 silica beads are conveniently coated with a dense layer of silica that make them ideal for transvection or the separation of nucleic acids from Lysis Buffers used to collect clinical samples.
