Sartorius Stedim Biotech
This company has expanded its range of single-use membrane chromatography solutions with Sartobind Cassettes (photo), which are suitable for the capture of large proteins. This pod-like modular system has been developed for commercial applications in both capture and polishing. New Sartobind cassettes offer the same flow path, bed heights (4 and 8 mm) and void volume ratios as Sartobind capsules, and are compatible with Q, S, STIC PA and phenyl ligands. The new design goes beyond the previous 5-L size limitation for capsule formats, expanding the boundaries of membrane chromatography. Multiple cassettes, each with 0.8- or 1.6-L membrane volume, can be set up in three different stainless-steel holders, resulting in maximum membrane volumes of 20, 50 or 100 L, respectively. — Sartorius Stedim Biotech, Göttingen, Germany
