Amicon® Ultra 15 mL Centrifugal Filters

 Amicon® Ultra 15 mL Filters for Protein Purification and Concentration

Amicon® Ultra 15 mL centrifugal filter devices provide fast ultrafiltration, with the capability for high concentration factors and easy concentrate recovery from dilute and complex sample matrices.

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® Ultra 15 mL filters deliver the highest recovery with short spin times.

 Advantages

  • High recovery Ultracel® regenerated cellulose membrane in a range of molecular weight cut-offs
  • High retentate recovery of >90%
  • Vertical membrane reduces concentration polarization for ultra-fast spin times (as fast as 10–15 minutes)
  • Heat-sealed membrane minimizes downstream extractables
  • 100% integrity tested for reliable performance
  • Convenient sample monitoring with translucent housing and volume gradations
  • Direct pipetter sample access eliminates processing step to recover concentrate
  • High concentration factors of 80–100X
