Product Description

The BIOBASE Scanning UV-Vis Spectrophotometer BK-UV1900, BK-UV1900PC, BK-V1900, and BK-V1900PC are high-precision analytical instruments designed for quantitative and qualitative laboratory analysis. Ideal for research institutions, environmental monitoring, pharmaceuticals, food testing, and chemical laboratories, these systems deliver reliable optical performance with ultra-low stray light and high wavelength accuracy.

Featuring a hermetically sealed optical system with high-grade grating (1200 lines/mm) and SiO₂-coated mirrors, the instrument ensures stable, accurate, and long-term measurement reliability. The integrated GLP self-check function automatically verifies wavelength and photometric accuracy, while intelligent lamp monitoring tracks deuterium and tungsten lamp life in real time.

The PC versions include dedicated scanning software for enhanced data processing and curve analysis.

Factory direct supply with delivery within 7 days.
