High Pressure Valves Introduction | |
Rheodyne valves fit virtually any flow control application. There are valves for preparative, analytical, nano, and microscale analysis in a variety of flow configurations. Pressure ratings of the valves in this chapter range from 125 psi (9 bar) to 15,000 psi (1,034 bar). MX Series II™ Modules are actuated electronically and can be easily adapted to existing instrumentation using contact closure, BCD, I2C, USB, or used as stand alone devices. Industry standard sample injectors and switching valves are designed for manual actuation. Locate the valve module and flow configuration of choice using the table below. | |
Genuine Rheodyne valve accessories are also featured in this chapter. | |
- Vespel®, Tefzel® and PEEK™ Rotor Seals; Stainless Steel and PEEK Stators - Rheodyne RheBuild® Kits - Stainless Steel and PEEK Sample Loops - Needle Port Accessories, Mounting Brackets, and the Rheodyne Wrench Upchurch Scientific® Micro Injection Port Adapters are also available. |

A
Compatible Family of productivity Enhancing Solutions for Laboratory
Automation
- Increase
Laboratory Productivity / Expand Laboratory Capabilities / Increase Reproducibility / Improve Analytical Results / Increase Equipment Reliability / Save Time and Money |
|
Today's HPLC fluid injection and switching applications require speed, precision and flexibility. Rheodyne®'s MX Series of productivity enhancing solutions for laboratory automation answer these needs. These completely self-contained, electrically actuated valves are available in a variety of flow paths for nano-, micro-, and analytical-scale applications. | |
"Manual"
or Automatic Actuation
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. |
Outstanding Performance 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." |
Nano-Scale
modules
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. |
Versatile MX Modules are designed to increase productivity, expand laboratory capabilities, save time, and make life easier. |
Analytical-Scale Modules 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. | Typical
