From Routine Analysis To Research, Employing
The Highest Level of Sensitivity In The World!

RF-5301PC - Fluoresence
Compared to absorbance methods, fluorescence sensitivity is tens to thousands times better - this means that you can analyze nanogram to picogram samples with great results.

Fluorescence can be used also to identify a specific molecule in a complex background. When the compound of interest does not exhibit natural fluorescence, functional group-specific probes may be used to label the compound and assist your research. The synchronous scanning mode allows mixtures of fluorochromes to be analyzed.

The personal computer directly controls the instrument for data acquisition and processing. The Windows friendly operating environment allows you to perform measurement, data processing, editing and recording in one continuous operation with a click of the mouse. Using the Copy Graph function, measurement data or spectra may be easily transferred to word processing or spreadsheet software for preparation of documents or additional calculations.

The essence of fluorescence analysis is sensitivity. The high throughput optical system in the RF-5301PC employs a blazed holographic grating, photomultiplier and digital signal processing to provide the highest level S/N ratio attainable.

Working in the WindowsTM environment makes operation intuitive. The software is driven by pull-down menus displayed at the top of your screen, that can be selected with just a click of the mouse. For the beginner, on-line HELP is available to guide you through each function. You can customize the software with SpeedBox, an innovative tool that eliminates keystrokes and enables you to assign icons for commonly used menu commands. With the RF-5301PC software, storage, retrieval and other file management is quick and simple.
