BG-30 or BG-5 columns are recommended for batch (stirred tank) or gravity flow purifications due to their convenient application. The
larger column BG-30 has a working volume of 30ml with volumetric marks in the first 20ml (at 1ml interval). This column is ideal for resin
volume of 1ml to 10ml. The smaller column BG-5 has a working volume of up to 5ml and is ideal for working resin volume of 0.1ml to
1ml. With the BG columns, the entire protein purification process (resin equilibration, binding, washing, elution and regeneration) can be
achieved cost-effectively using the same device. Also, for process flexibility, the exact volume of required resin can be loaded to the
column of choice without limitation. These columns can be either re-used after proper cleaning or applied in a disposable way.
