Review date: 29 Jan 2014

Application Area: Protein Purification And Concentration
Amicon Ultra-15 Centrifugal Filter Units

"Amicon® Ultra-15 Centrifugal Filter Units are useful for protein purification and concentration. This filter device can remove proteins bellow 30 kDa. This filter device can be used to concentrate a pure protein with molecular mass above 30 kDa. The recommended velocity to spin this device is 2000 RPM, however when the filter is used for long time it may be useful to decrease this speed to 1500 RPM as there is always chance of a loss of protein. The second more important thing is to fill this device to the maximum of 13 ml as there is a chance of filter loss above this volume. This is suitable for small scale protein concentration. I recommend it to use for protein separation and concentration and to store this device either in 20% Ethanol or 0.02% Na-azide solution. "

Amicon Ultra-15 Centrifugal Filter Units

"Works well for slow centrifugation. Limited reversibility, a wide range of metal detectability. Variability of data is limited. Affordable; service rep was very good."

Review date: 26 Jan 2012

Application Area: Cell Biology
Amicon Ultra-15 Centrifugal Filter Units

"Millipore concentrations are very easy to use and are a great value for the money spent. I use specifically the 15mL concentrators at 10,000 molecular weight and I would highly recommend this product."

Description

 

• 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 pipettor sample access eliminates processing step to recover concentrate
• High concentration factors of 80–100X
