The VUV-40F is a dual beam, fixed wavelength, optical absorbance detector for liquid chromatography. The OEM module can be configured in a variety of ways from standalone operation to incorporation into a dedicated analyzer.

Variety of Light Sources

The VUV-40F can be configured with Hg, LED, Deuterium or Xenon light sources allowing a wide selection of light throughput, wavelength selection, power and sizes to fit any application.

Dual Beam

Compact patented design keeps the optical unit small but with the performance of larger instruments. This allows smaller dedicated OEM designs or smaller footprint for stand-alone instruments.

Advanced Electronics

High-resolution output can be accessed by USB or IEE488 protocols. Fully programmable parameters using a host computer are permanently stored in non-volatile memory. Easily integrated with OEM analytical systems. Stand-alone operation configuration for private label instruments is also available.

Original Equipment Manufacturer offers complete units for private label to individual modules designed to fit your specific application. For further information please contact us.
