The centrifugal filter from Millipore provides a 50 fold concentration with 98% recovery rates in as little as 10 minutes of centrifugation. The Amicon Ultra 2.0 mL provides the highest recovery with the fastest spin times in its product class. The device contains an ultrafiltration membrane with molecular weight cut-offs (MWCO) of 3,000, 10,000, 30,000, 50,000, or 100,000.
The Amicon Ultra-2.0 mL device combines a vertical membrane orientation with a reverse spin capability, enabling both fast concentration and high yields. An engineered dead stop provides predictable final sample volumes and prevents spinning samples to dryness, which can denature labile proteins.
