Pierce™ Centrifuge Columns are convenient tools for handling 40 µl to 10 ml of an affinity support for purification.

• Made from low protein binding polypropylene for compatibility with protein purification
• Filter type, pore size: Polyethylene filter, ~30 µm pore size
• Twist-off bottom

These centrifuge columns can be used in either spin or gravity-flow format.

Applications:
Affinity purification, affinity chromatography
Immunodepletion
Ion exchange resins
Gel filtration, desalting, buffer exchange

The spin format reduces sample processing time and makes column washing and elution more efficient. For gravity-flow procedures and when slow processing time is desired for binding steps with dilute samples, Column Extenders can be used to increase the column reservoir capacity. Use the any combination of processing techniques to get the best possible chromatography results. Store at room temperature.
