The Biobase UV/VIS Spectrophotometer (Model: BK-UV1800 / BK-UV1800PC) is a high-precision, single-beam spectrophotometric system designed for accurate and versatile measurements across a broad wavelength range of 190–1100 nm. Equipped with advanced optics, SiO₂-coated mirrors, and automated calibration functions, this system is ideal for applications in life sciences, environmental testing, quality control, pharmaceuticals, and research laboratories.
It features GLP-compliant self-checking, automatic wavelength and dark current calibration, and expandable software options for quantitative, multi-wavelength, spectrum scanning, DNA/protein testing, and kinetic assays (PC version only). The system offers excellent performance with photometric accuracy of ±0.002A and a color TFT LCD display for intuitive control.
