BioLogic DuoFlow Chromatography Systems


BioLogic DuoFlow Systems. These are medium pressure laboratory scale chromatography systems for protein purification. These systems are modular, capable of running at high flow rates with back pressures up to 3,500 psi, with pH monitoring, buffer blending, and column scouting capabilities. It can be used in conjunction with a fraction collector for unattended operation.
