BRT-1100UV UV Vis Spectrophotometer

The BRT-1100-UV UV Vis Spectrophotometer is a reliable, high-precision benchtop analytical instrument engineered with a 1200 lines/mm holographic grating, a high-sensitivity silicon photovoltaic cell detector, and a 128×64 graphic dot-matrix LCD screen. Designed for routine chemical profiling, environmental monitoring, pharmaceutical QA/QC, and educational laboratories, it delivers stable optical performance across the 200 nm to 1000 nm spectral range with a 4 nm spectral bandwidth, ±2 nm wavelength accuracy, and ≤1 nm wavelength repeatability.

Driven by dual tungsten halogen and imported deuterium light sources with automated wavelength adjustment and zero-calibration controls, this compact 14 kg UV Vis Spectrophotometer features low stray light (≤0.2%T) and excellent baseline stability (≤0.002 A/h drift). Featuring internal memory for 200 datasets and standard curves, a spacious sample chamber accommodating 5 mm to 100 mm cuvettes, USB data connectivity, and parallel LPT printer support, the BRT-1100-UV ensures simple, repeatable laboratory testing.
