The FS5 v2, which builds on the success of the original FS5, raises the bar for fluorescence spectroscopy with its improved sensitivity, increased capabilities, and small, user-friendly design.
The FS5 v2 is designed to thoroughly characterize various samples, such as solids, liquid solutions, powders, and thin films. Its quick-exchange sample holders and advanced automation make it adaptable to a variety of industry and research needs.
Key Features
- Unmatched Sensitivity: The FS5 v2 features an outstanding signal-to-noise ratio of 12000:1, allowing it to detect even the faintest signals.
- Widest Spectral Coverage: The FS5 v2 creates new opportunities for examining a wider variety of samples, thanks to its extended NIR detection range of up to 2.05 µm.
- Advanced Automation: The most recent version of the “Fluoracle” software provides complete instrument control, from data collection to sophisticated analysis, increasing the efficiency of experiments beyond all previous levels.
- Two Key Abilities in One Unit: FS5 v2 eliminates the need for a separate spectrophotometer by providing absorption and fluorescence spectra.
- Comprehensive Capabilities: The FS5 v2 supports a wide range of applications, including steady-state fluorescence, quantum yield, phosphorescence, and time-resolved measurements.
