F96S Fluorescence Spectrophotometer (CAT#: STEM-S-0021-LGH)

Two operating modes, fluorescence intensity and luminescence intensity, can be selected. Fluorescence spectrum scanning, fluorescence kinetic measurement and quantitative analysis can be performed in the fluorescence intensity mode.
365nm excitation wavelength water Raman peak signal-to-noise ratio>150 (P-P), excellent high detection sensitivity can make the determination of samples with low detection limit very accurate and simple.
Provides 10 emission spectrum scan speed options, including high-speed low-noise scan and fine scan. Among them, the ultrafast scan is 30000nm/min, and the full spectrum scan can be completed in about 1 second.
Supports stand-alone and online modes. In stand-alone state, the built-in microcomputer system provides functions such as fluorescence intensity measurement, direct reading of concentration, automatic zero adjustment, and automatic background subtraction. In online state, qualitative/quantitative software can be used to monitor the instrument through the USB2.0 interface. Perform control and data acquisition analysis.
The high-intensity 150W xenon lamp is continuous spectrum and provides excellent test stability in the wavelength range of 200nm to 850nm.
It has the function of normalizing fluorescence values, which can eliminate the problem of incomparability of fluorescence values ​​between different fluorescence photometers, and facilitate the unified evaluation of experimental reports of students in college teaching.
The qualitative/quantitative software is rich in functions. The wavelength scanning and time scanning modes of the emission spectrum can provide spectrum scaling, multi-spectrum comparison, spectrum calculation, peak and valley detection, peak area calculation and 1-4 derivative spectrum functions; the quantitative test mode can use the standard curve Method and undetermined coefficient method to detect sample concentration, provide first-order, second-order and third-order linear fitting operations, and can customize the concentration unit.
Supports a variety of measurement accessories, including single-well sample cell holder, multi-purpose fluorescence sample holder, 202μL microcentrifuge tube measurement accessory, capillary micro-sample measurement accessory, fluorescent sample semi-automatic sample injection accessory, single-well sample cell adapter, membrane samples and powders Shape sample measurement accessories and jacket-type sample cell holder, etc. Rich accessories greatly expand the application range of the instrument.
The compact model saves a lot of desk space.
