SciLog's PureTec System optimizes protein yield and maintains the safety of your Tangential Flow Filtration (TFF) applications. PureTec displays over 17 filtration parameters including transmembrane pressure (TMP), inlet pressure, permeate pressure, retentate pressure, feed rate, flux rate, recirculation rate, and it quantifies permeate. Measuring and monitoring more parameters enables greater control and a diminished risk of sample loss. PureTec provides instantaneous overviews of the filtration progress and the status of both concentration and diafiltration (washing) of protein solutions. It can collect, print or send data to Excel and also generate graphs. PureTec can implement programmable ramps of feed rate and/or TMP, can implement filtration with a constant TMP and can implement filtration with a constant feed rate. The system is compatible with TFF filter cartridges from all manufacturers including Millipore, Pall, Sartorius, and GE. The PureTec is excellent for process development and lab-scale purification.
