Valve with extremely low transmission gradient

The unique features of the Ultra Low Carryover Gradient Valve ensure high accuracy of gradient generation in quaternary HPLC designs.

This is achieved through a combination of fast response times and a patented low volume, high flow fluid design.

This miniaturized valve allows a reduction in the overall size of the instrument and reduces the dead volume of the system. The exceptionally long service life and resistance to crystallization ensure that the valve will last throughout the life of the instrument.

Ultra low transmission valve

The Ultra Low Carryover Valve has both unprecedented low carryover and the ability to reduce fluid circuit complexity by replacing multiple valves with a single valve. The valve uses a patent-pending method to increase throughput and reduce fluid waste by reducing wash times. In addition, the Ultra Low Carryover Valve offers superior performance as a gradient proportioning valve for HPLC, HbA1c and other life science applications.
