Product Name: USB2000-FLG Gated Fluorescence Spectrometer

Product Description

The USB2000-FLG is a high-sensitivity spectrofluorometer that is preconfigured for fluorescence applications from 380-1050 nm. 

We utilize a proprietary thin film technology and a time-gated spectrometer to provide a spectrofluorometer that is 20 percent more sensitive than the standard USB2000 Spectrometer. The USB2000-FLG is available for $2999.

Features

AgPlus Mirrors increase system sensitivity by 20% over standard USB2000

Gated mode eliminates scattered excitation light to enhance phosphorescence measurements

AgPlus Mirrors 

We replaced our standard mirrors with our proprietary AgPlus Ag-coated mirrors to increase reflectance, which in turn increases the sensitivity of the spectrometer by 10-35% percent. Not only do these mirrors create a more sensitive spectrometer, they also absorb nearly all UV light, virtually eliminating the excitation source's spectra from interfering with the sample spectra. Pairs of AgPlus mirrors (item SAG+UPG) are available for $250.

Gated Phosphorescence Mode

The USB2000-FLG is preloaded with variable-delay gating microcode, which allows you to select a delay (from 5-500 microseconds) between the light turning on and the start of the spectrometer's integration time, or the amount of time the detector sees the sample. In this mode, the spectrometer only detects the sample light when the source is off. However, in order to use the gated phosphorescence mode, your fluorophore must have a long fluorescence lifetime. Those working with lanthanides and phosphorescent materials will find the gated phosphorescence mode particularly useful.

L2 Detector Collection Lens 

The USB2000-FLG's detector window is fitted with an L2 Detector Collection Lens. This cylindrical lens increases the spectrometer's light-collection efficiency and reduces stray light. The L2 is especially useful with a large-diameter fiber for low light-level applications.

Accessory Filters

The USB2000-FLG can be used with our LVF-series Linear Variable Filters to construct systems with excellent separation of excitation and fluorescence energy. Use our LVF-L Linear Variable Low-pass Filter to fine tune your excitation source for maximum signal with minimum overlap; and/or use our LVF-H Linear Variable High-pass Filter on the detection side. Inline holders and cuvette fixtures make deployment of these filters easy.

Applications 

The USB2000-FLG can detect fluorophores in liquids and powders, and from surfaces. We use the USB2000-FLG in our EDS2000 System to detect anthrax. The USB2000-FLG is field-portable -- use it to detect fluorescence in coral, fruit and other flora and fauna.
