Ultra Fast Centrifugal Filter Devices

Amicon® Ultra Centrifugal Filters from Millipore combine a vertical membrane orientation with a unique reverse spin capability, enabling both fast concentration and high yields.

Offering 50-fold concentration with 98% recovery rates in as little as 10 minutes of centrifugation, Amicon Ultra devices provide the highest recovery with the fastest spin times in their product class. The devices contain an ultrafiltration membrane with molecular weight cut-offs (MWCO) of 3,000, 10,000, 30,000, 50,000, or 100,000.

An engineered dead stop provides predictable final sample volumes and prevents spinning samples to dryness, which can denature labile proteins.
The devices are available in a range of volumes:
• 0.5 mL
• 2 mL NEW!
• 4 mL
• 15 mL

Amicon Ultra devices have become standard tools for sample preparation via frequent citations in peer-reviewed literature.
