Spin concentrators are devices used to concentrate protein samples via low-speed centrifugation through MWCo filters into a collection tube.

• Contains a polyethersulfone (PES) membrane that is compatible with biological fluids and most aqueous solutions with pore sizes of 50 kDa
• Active membrane area of 2.0 cm^₂ or 4.0 cm²
• Durable and designed to minimize membrane fouling and allow fast concentration, even with particles in the solution

Designed to fit a standard 15 ml conical collection tube or a 50 ml collection tube (not provided with concentrator). Designed to be used in either swing-bucket or fixed angle rotor centrifuge equipment at maximum 5000 g or 2000 g.
