Empty Spin Columns have a maximum filling volume of 700 µl and are ideal for rapid protein purification from small sample volumes. They come with inserted frits (mesh size 10 µm), screw caps, and snap-off plugs and are compatible with the conventional 1.5 ml or 2.0 ml reaction tubes. The frit in the lower part of the column ensures that the resin remains in the spin column while the sample or buffer flows through rapidly during the centrifugation process.
The empty spin columns are offered without resin and purification buffer to facilitate a customer-specific application and experimental design, such as when specific buffer conditions are required. For purification of Strep-tag®II or Twin-Strep-tag® fusion proteins, the combination with Strep-Tactin®XT 4Flow® high capacity resin is recommended.
