Millipore Amicon Centrifugal Filter Ultra 100K Ultracel 0.5 ml Pack of 68

The Millipore UFC510096 Amicon Ultra Centrifugal Filter is a single-use, 0.5 mL capacity ultrafiltration device designed for fast and efficient concentration, purification, and desalting of biological samples. It features a 100 kDa (kilodalton) nominal molecular weight cut-off (NMWL) Ultracel membrane, which is made of regenerated cellulose, known for its extremely low protein binding and high recovery rates (typically >90%). The filter's unique vertical membrane design minimizes solute polarization and fouling, enabling rapid processing times, usually between 10 to 30 minutes, and allowing for up to a 30-fold concentration. It is compatible with centrifuges that have fixed-angle rotors and wells for 1.5 mL tubes. A key feature is its "reverse spin" capability, which ensures consistent and near-total recovery of the concentrated sample.
