HPLC Valves "Made in Germany"

These high quality valves can be switched both manually and automatically by means of motor drive at the touch of a button or via RS232 by the HPLC software. They correspond in their properties and switching behavior to the Rheodyne valves from the US. The valves with PEEK or stainless steel stator are intended for analytical and preparative applications and are used in the liquid chromatography for high pressure purifications.


NO-FLOW-INTERRUPTION "NFI"


NO-FLOW-INTERRUPTION

The HPLC valves for sample injection with the item no. 100003, 100012 and 100041 to 44 are equipped with the NFI technology. While switching the NFI reduces the pressure peaks to a minimum. This unique geometry of the HPLC valve stator interrupts the flow path only for a very short time thus preventing a sudden pressure increase following flow interruption.

Motor Drive for HPLC Valves

The valves with the item numbers 100003, 100009, 100012, 100014 and 100054 can be mounted without modification at the motor drive. The mounted HPLC valve can be selected on the display, making it immediately ready for operation. The motor drive switches very quickly. It can be operated both manually via two buttons on the front and automatically via RS232 or USB and the HPLC software. Furthermore, contacts in the form of locks allow valve reset and switching of the position.
