Amicon® Ultra-0.5 centrifugal filter devices provide fast ultrafiltration, with the capability for high concentration factors and easy concentrate recovery from dilute and complex sample matrices. For example, Cytochrome c (12.4 kDa) at 0.25 mg/ml initial concentration is typically retained at >95%.
Solute polarization and subsequent fouling of the membrane are minimized by the vertical design, and a physical deadstop in the filter device prevents spinning to dryness and potential sample loss. Efficient recovery of the concentrated sample (retained species) is achieved by a convenient reverse spin step after collecting the filtrate.
Amicon® Ultra-0.5 devices are supplied non-sterile and are for single use only. With their vertical membrane design and reverse spin, Amicon® Ultra 0.5 mL filters deliver great performance and lower spin times.
