Unlocking Advanced Purification

Membrane chromatography built to scale. 

Rapid cycle times, high binding capacity, and consistent performance 

Designed for Modern Biologics 

Purilogics is innovating the purification process with membrane chromatography to meet the demands of today's complex biologics. Purexa® membranes overcome the limitations of traditional resin-based systems with rapid changeover, high recovery, and reliable performance. 

Fast flow rates, easy setup, and no incubation periods reduce production stress. Durable and efficient, our membranes cycle quickly without degradation or fouling — delivering consistent results at any scale. .

Purexa™ PrA mini - Fast Antibody Purification within 1 Minute
Purexa™ PrA mini - Fast Antibody Purification within 1 Minute

Purexa™ PrA mini is designed for rapid processing of small quantity of antibodies, especially at low titers. During elution, the first 0.5 mL was discarded. As is shown in the fitures, a majority of the antibody was eluted in the second 0.5 mL elution fraction, which had a concentration of 3.3 mg/mL and was corresponding to a recovery of 78%.
