Collection: UV/VIS Measuring Reagents

UV/VIS Measuring Reagents — a group of spectrophotometry-grade reagents and solvents used to generate or measure color absorbance in the ultraviolet and visible light ranges, including complexometric indicators and high-purity solvents free from fluorescent or UV-absorbing impurities. This group supports the reliability of quantitative optical measurements.

UV/VIS Measuring Reagents are used by analytical and quality control laboratories for color-forming reactions (colorimetry) in determining the content of target compounds, such as measuring free chlorine with ABTS-based reagents or determining metal cations through colored complexes with barium chloranilate. Spectrophotometry-grade solvents are used as background measurement media because of their low UV absorbance at the working wavelength.

Example products in this collection: TCI A5200 30931-67-0 AzBTS [=2,2'-Azinobis(3-ethylbenzothiazoline-6-sulfonic Acid Ammonium Salt)] [Spectrophotometric reagent for free chlorine], TCI C0001 561-20-6 Cacotheline Monohydrate, TCI A0509 90-44-8 Anthrone, TCI C0078 32458-20-1 Barium Chloranilate Trihydrate, TCI A0228 123-86-4 Butyl Acetate [for Spectrophotometry], TCI C0175 67-66-3 Chloroform (stabilized with Ethanol) [for Spectrophotometry], TCI A0054 67-64-1 Acetone [for Spectrophotometry], TCI C0696 110-82-7 Cyclohexane [for Spectrophotometry].

Pay attention to the spectroscopic purity grade (grade for spectrophotometry), the wavelength range free of interfering absorbance, and the stability of color reagents against light and time. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
