BRT-850 FTIR Spectrometer

The BRT-850 FTIR Spectrometer is a high-stability benchtop Fourier transform infrared analytical instrument engineered specifically for academic research, university teaching, industrial quality control, and advanced material analysis. Designed for pharmaceutical testing, petrochemical QA, polymer profiling, food safety evaluation, and environmental analysis, it delivers certified molecular spectroscopy across the 7800 cm⁻¹ to 375 cm⁻¹ spectral range with 1 cm⁻¹ optical resolution.

Featuring a sealed Michelson interferometer with a 30° incidence angle, an imported US-made KBr/Ge beamsplitter, a long-life US-imported air-cooled IR source, and a moisture-protected DLATGS detector, this high-precision FTIR Spectrometer guarantees exceptional baseline stability and vibration resistance (SNR > 30,000:1). Built on an integrated cast-aluminum optical bench with tool-free accessory positioning, the 14 kg BRT-850 combines industrial durability with effortless laboratory operation.
