The Agilent 1290 Infinity II Preparative Open-Bed Fraction Collector enables high-capacity fraction collection of purified peaks for semi-preparative and preparative-scale LC purification. Collect milligrams to multiple grams of your target compounds effectively and intuitively. This fraction collector facilitates easy handling of a wide variety of collection vessels with a capacity up to 5.9 liter using 25 x 150 mm tubes (od xl). The fraction collector’s draws and racks use identification tags to detect vessel dimensions automatically. With novel robotic technology,the fast X-Z-theta probe minimizes sample loss during movement between vessels. Unique fraction delay sensor technology determines fraction delay volumes automatically to collect just in time. The fraction collector is optimized for flow rates up to 200 mL/min. and can be integrated seamlessly with any Agilent solvent delivery module, autosampler or detector.
