The systems's wide flow rate range (from the 333 and 334 Pumps) allows for both semi-preparative and preparative separations. High pumping power accommodates a wide range of preparative column sizes. All injection modules feature a continuous flow path design. The system can accommodate large injection volumes with minimal sample waste and carryover. The new rinse station system incorporates a flowing jet wash and allows the use of up to two different rinse solvents.
