HIGH PRESSURE VALVES INTRODUCTION

- Increase Laboratory Productivity /
Expand Laboratory Capabilities / Increase Reproducibility / Improve Analytical Results / Increase Equipment Reliability / Save Time and Money

MX Modules can be operated by push button, allowing them to function as "manual" valves, or by contact closure for automated remote control. For multiple automated valve applications, a unique "Snap n' Stack" System allows units to be stacked vertically or connected horizontally to conserve bench space and reduce connection volumes.
These small, innovative packages and their simple installation make MX Modules the solutions of choice for all high-pressure fluid switching and sample injection applications. Many microscale applications may utilize the nanoscale modules.

MX Modules are also available in Analytical-Scale Six- and Ten-Port Switching Valves with low dispersion. All MX Modules incorporate Rheodyne's time tested miniature "Mighty Valve."

With a mere 10nL internal sample chamber and, more importantly, outstanding dispersion characteristics, Rheodyne's MX Nano-Injector is the ultimate solution for nano- as well as microscale applications.
All three Nano-Scale MX Modules take advantage of Rheodyne's proprietary biocompatible DuraLife™ II technology for greatly extended duty cycles. MX nanodispersion Six- and Ten-Port Switching Modules are ideal for online sample preparation and LC/MS column switching with minimal band broadening.

MX Modules are designed to increase productivity, expand laboratory capabilities, save time, and make life easier.

The MX Semi-Automatic Injector combines the ease of use of Rheodyne's industry standard manual injectors with the precision actuation of an electrically actuated valve. With its specially designed needle port, sample is loaded directly into the valve. The push of a button injects your sample. By connecting the injector to a single contact closure, a sample can be loaded during system equilibration and injected automatically when the system is ready.

NANO^-SCALE SAMPLE INJECTOR

NANO-SCALE TWO-POSITION, SIX^-PORT SWITCHING MODULE

Rheodyne® has created the world's smallest injection valve in a ready-to-use module. The MX Nano Injector has a 10nL internal sample chamber and outstanding low dispersion characteristics. The MX Nano Injector can also be used for microscale applications. Maximum pressure is 5,000 psi (345 bar).

Rheodyne's MX Nano Six-Port Switching Module is designed to automate a variety of applications. Like the Nano Injector, this module can be operated by manual push button or, in remote mode, automatically by contact closure with a controlling instrument.

The MX Nano Injector takes advantage of Rheodyne's proprietary biocompatible DuraLife™ II technology for greatly extended duty cycles in a typical laboratory automation application.

Flow passages are 0.10mm (0.004") in diameter with a port-to-port volume of 25nL. This module is rated to 5,000 psi (345 bar).

ANALYTICAL-SCALE SYRINGE LOADING SAMPLE INJECTORS

From the 7105 to the 7725i, Rheodyne has been the world's leader in HPLC sample injection for 25 years. The MX Semi-Automatic Injector is the next step in that legacy. By combining the ease of use of a manual injector with the precision actuation of a motorized valve, the MX Semi-Automatic Injector is the ideal solution for laboratory sample injection.

A specially designed needle port allows sample to be loaded directly into the valve. The push of a button begins sample injection in 120ms. The MX Semi-Automatic Injector is capable of complete automation.

Flow passages are 0.30 mm (0.010") in diameter with a port-to-port volume of 500nL. This module is rated to 5,000 psi (345 bar).
