Amicon(R) Ultra-4 Centrifugal Filter Unit

Descrição detalhada : Amicon(R) Ultra 4 mL centrifugal devices with Ultracel(R) 10,000 Dalton molecular weight cutoff filters provide fast ultrafiltration, and reliable retention of macromolecules. For example, Cytochrome C (12.4 kDa) at 0.25 mg/ml initial concentration is retained at >95% . The vertical design and available membrane surface area provide fast sample processing, high sample recovery (typically greater than 90% of dilute starting solution), and the capability for 80-fold concentration. 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.The concentrate is collected from the filter device sample reservoir using a pipetter, while the ultrafiltrate is collected in the provided centrifuge tube. The device can be spun in a swinging bucket or fixed angle rotor. With their vertical membrane design and deadstop, Amicon(R) Ultra 15 mL filters deliver the highest recovery with short spin times.
