Centrifugal Filters

Broad chemical compatibility: Heat-sealed membrane eliminates adhesives and downstream extractables; compatible with pH 1 to 9 o Reverse spin recovery: Enables maximum protein recovery without introducing pipetting errors; low binding membrane and polypropylene housing for > 90% sample recovery 

*Maximum initial sample volume: Swinging bucket(10.0mL), Fixed angle rotor(10.0mL)  

*Typical final concentrate volume: 200μL 

*Maximum relative centrifugal force: Swinging bucket rotor(4,000g), Fixed angle rotor(5,000g)

*Active membrane area: 5.48c㎡

*Protein Concentration, Nucleic Acid Concentraion, Buffer Exchange, Dialysis, Desalting 

*Dead stop: Avoids spinning to dryness, provides a predictable concentration factor and no need to calibrate for several samples to run in parallel

*Available in multiple pore sizes with the following defined Molecular Weight Cut-Offs (MWCO): 30, 50 and 100KD 

*Vertical membranes: Aligned with filtrate rather than perpendicular for less clogging, less waste and faster filtration; capable of 25- to 80-fold concentration in a single step concentration in a single step

*Reliable: Spin precious samples with confidence in one robust, sleek unit that prevents leakage 

*Ultrafiltration membrane is neutrally charged, rendering it low binding for enhanced flux and recovery. The membrane has excellent chemical resistance and very low extractables 

*Temperature range: -20°C to +50C° 

*Autoclavability: No
