lightproof flow-through cell

The Lightproof Flow-Through Cell

high-precision instrument component designed for use in dissolution testing systems, UV-Vis spectroscopy, and other pharmaceutical or analytical applications requiring continuous monitoring of liquid samples. Engineered with advanced materials and a thoughtful structural design, this flow-through cell ensures high sensitivity and consistent performance while effectively protecting light-sensitive compounds from degradation.

Advanced Material Composition

At the core of its superior performance is its robust construction. The flow-through cell is made of a combination of black and clear quartz, materials known for their exceptional chemical resistance, high optical clarity, and excellent thermal stability. The clear quartz section allows for accurate spectroscopic analysis, ensuring that the passage of light through the sample is undistorted and highly reproducible. The black quartz housing serves a crucial function in shielding the contents from external light exposure, making the cell ideal for analyzing light-sensitive samples such as certain pharmaceuticals, dyes, or biological compounds.

Optimized Design for Accurate Analysis

Designed with precision in mind, the flow-through cell includes an inner quartz tube, which acts as the main path for the solvent or test medium. This design minimizes dead volume, ensures smooth flow, and enhances the accuracy of concentration measurements by providing a stable and consistent optical path. The inner tube can be easily cleaned or replaced, supporting both maintenance efficiency and long-term usability.

Additionally, the cell is equipped with a top metal connection tube, which can be easily linked to an external tubing system, allowing for flexible integration into various lab setups and automated testing workflows. This feature is particularly beneficial in systems that require continuous circulation of the sample, such as closed-loop dissolution testing, where consistent sample conditions are critical for reproducibility and compliance with regulatory standards.

Versatile Applications

The Lightproof Flow-Through Cell is ideal for laboratories focused on pharmaceutical development, chemical analysis, environmental monitoring, and academic research. Its ability to deliver real-time analytical data with high accuracy makes it a reliable component for:

• Dissolution testing of solid dosage forms, ensuring compliance with pharmacopeial methods.

• UV-Vis spectrophotometric measurements in a flow-through configuration.

• Analysis of light-sensitive substances, where exposure to ambient light could compromise the integrity of results.

• Automated sampling systems, where continuous flow and in-line measurement are required.

Quality, Compatibility, and Customization

Each flow-through cell is manufactured under stringent quality controls, ensuring reliability and performance across applications. The design supports compatibility with a wide range of laboratory instruments and pumps, and can be customized based on your specific analytical needs.
