EmailThe 2000A UV-Visible Spectrophotometer is a laboratory instrument that generates ultraviolet and visible electromagnetic radiation with high stability, monochromaticity, and collimation. The incident light is split into two beams—one passes through a reference cell (blank), and the other through the sample cell. By comparing the intensity of light before and after passing through the sample at various wavelengths, the instrument determines the sample’s absorbance or transmittance. The detector receives the transmitted signals and converts them into electrical signals for analysis.
Features
Dual Optical Path & Dual Beam System: Offers higher resolution, lower stray light, and improved stability and reliability for more accurate analysis.
Socket-Type Tungsten and Deuterium Lamps: Simplifies maintenance by eliminating the need for optical realignment during lamp replacement.
User-Friendly Design: Enhances flexibility and ease of use for operators and maintenance personnel.
Suspended Optical System: Isolates the optical system from baseplate deformation and external vibrations, improving overall stability and reliability.
Premium Imported Components: Reduce stray light and enhance the instrument’s performance and durability.
Versatile Accessories: Supports optional modules such as an automatic 8-cell holder, micro cuvette rack, thermostatic autosampler, reflection accessories, and integrating sphere—broadening its application range.
