Description Sepragen knows how to treat separation anxiety. The company makes liquid purification equipment to separate substances into their basic chemical components (for the geeky, it relies on radial flow and axial flow chromatography processes). Pharmaceutical companies and food and beverage makers use the equipment for such applications as purifying biological drugs, processing dairy products, and enhancing the protein content of infant formula. Products include liquid chromatography columns, chromatography workstations, software, and separations media. Sepragen sells to such high-profile customers as Amgen, Asahi Glass, Baxter International, and Schering Plough.
