FluorEssence™ for Windows® sets a new standard for fluorescence software. FluorEssence™ merges spectrofluorometer data-acquisition directly to the famous processing power of Origin® software.

Simple clicks let you select a scan type, accessory or bring back a complete experimental set-up.

Revolutionize the Way You Operate Your Spectrofluorometer:

  • Simplified windows make data-acquisition intuitive even to the casual user.
  • With detector algebra, assemble input signals from different detectors into unique equations (including arithmetic or transcendental functions) that produce data in a format tailored to your application.
  • Select the special Real Time Control (RTC) window to optimize your run parameters before actually scanning.
  • Free video tutorials make FluorEssence™ even easier to learn.
  • Run a variety of accessories including polarizers, microwell-plate readers, temperature baths, autotitrators, phosphorimeters, and more.
  • Automatic correction for blanks and lamp output.
  • Change units for temperature, wavelength, and slit-width with the click of a mouse.

FluorEssence™ also includes the powerful processing and data-management tools of Origin® to streamline your laboratory’s operation.

Data-viewing, plotting, processing and management are all available, including extensive import and export facilities, view manipulation and creation, arithmetic applications, peak-picking and integration, data-management and much more!
