ChromaTan

ChromaTan is revolutionizing downstream bioprocessing with its continuous, column-free chromatography platform designed to intensify purification and lower costs. The company's core technology, BioRMB™, utilizes a true moving bed of resin slurry within a disposable flowpath, offering significant advantages in resin utilization, operational simplicity, and product recovery for advanced modalities. Having raised bridge financing and won industry awards, ChromaTan is currently focused on deploying process development units, scaling revenue, and pursuing a Series B round to expand its market presence and application scope.

The Kascade™ BioRMB™ platform is a patented, column-free, continuous chromatography system that uses a true moving bed of resin slurry for the intensified, low-pressure purification of biologics, offering dramatic reductions in resin use and operating costs.

ChromaTan competes with traditional packed-bed chromatography vendors (Cytiva, Merck) and multi-column continuous systems (Cytiva, Novasep). Its primary differentiation is its true moving bed, column-free architecture, which offers simpler design, lower resin use, and gentler processing specifically advantageous for fragile gene therapy products.
