Stray light Black solution

Stray Light Black Solution is a reference reagent used to check and verify the stray light performance of UV-Visible spectrophotometers in pharmaceutical and analytical laboratories.

🏭⚗️ Production
The solution is prepared by dissolving high-purity absorbing compounds in an appropriate solvent to produce a dark, homogeneous solution with high optical density. It is dispensed into sealed vials to ensure stability, prevent contamination, and maintain reproducible absorbance characteristics.

🔬 Properties
The solution is dark, stable under recommended storage conditions, and provides consistent absorbance across the UV and visible spectrum. Its high optical density allows accurate verification of stray light interference, ensuring spectrophotometer linearity and precision at low transmittance levels.

🧪 Applications
In pharmaceutical and analytical laboratories, the Stray Light Black Solution is used for calibration, verification, and performance qualification of spectrophotometers. It supports instrument qualification (IQ, OQ, PQ) and routine performance checks to ensure that stray light does not affect analytical measurements, maintaining accuracy and compliance with regulatory standards.

⚠️ Safety
The solution should be handled using standard laboratory safety practices, including gloves and protective eyewear. It should be stored in a cool, dark place, and waste should be disposed of according to laboratory safety regulations.
