IntroductionThe BK-UV series UV-Vis spectrophotometers are analytical instruments for quantitative and qualitative measurements in industrial and research laboratories, environmental monitoring and quality control.
Applications- Laboratory analysis and R&D
- Environmental monitoring and water analysis
- Quality control in chemical and material production
- Educational and clinical research support (non-diagnostic)
Key features- Single-beam optical design with 1200 lines/mm grating
- SiO2-coated optical mirror to minimize external contamination
- Automatic wavelength calibration, lamp switching and dark current calibration
- GLP self-check function for wavelength and photometric verification
- Integrated TFT display and USB outputs; PC software available for advanced analysis (PC models)
Basic functions- Photometry: measurement modes T (transmittance), A (absorbance), C, E
- Quantitation: linear fit and zero-through linear fit; three standard-curve modes (coefficient, standard input, standard read)
- Data handling: store up to 240 group curves, up to 240 data points per curve; dual- and triple-wavelength testing
