LC-V1200 Visible Spectrophotometer, 320-1100 nm and 4 nm Bandwidth (CAT#: STEM-BC-4078-ZJF)

The LC-V1200 is a single-beam visible spectrophotometer for qualitative and quantitative sample analysis. It determines sample absorbance and transmittance across the visible wavelength region. The instrument is applicable to pharmaceutical testing, clinical analysis, biochemistry, petrochemicals, environmental monitoring, food inspection, and quality control. It can also serve as a teaching and experimental instrument in colleges and universities. A 1200 lines/mm holographic grating provides spectral separation over the 320 to 1100 nm range. The high-brightness LED display clearly presents measurement values and operating information. Automatic wavelength adjustment is controlled by a high-precision subdivided drive mechanism. Automatic 0% transmittance zeroing improves operating convenience. The optimized self-collimating optical system reduces stray light, while USB connectivity supports computer communication and optional flash-drive data handling.
