UV/VIS Spectrophotometer BK-UV1800 190-1100nm, 2nm Bandwidth (CAT#: STEM-LT-1013-ZJF)

The BK-UV1800/1600 and BK-V1800/1600 series are precision single beam spectrophotometers designed for a wide range of analytical tasks. Covering UV/VIS (190–1100nm) or visible (320–1100nm) ranges, they offer multiple measurement modes including photometry, quantitative analysis, kinetics, and multi-wavelength testing. The PC models provide advanced data handling via included scanning software, while all versions feature high accuracy, low stray light, and stable performance. Different spectral bandwidth options (2nm or 4nm) allow users to select the best model for their analytical needs.
