Lightproof Flow-Through Cell — Precision Meets Protection in Spectroscopic Analysis

The Lightproof Flow-Through Cell is a specialized optical component designed for advanced spectroscopic applications where continuous sample flow, high chemical resistance, and protection from external light interference are critical. Engineered with premium materials and precision manufacturing, this flow-through cell delivers highly accurate, real-time analysis for researchers and lab professionals working in chemistry, pharmaceuticals, environmental science, biotechnology, and beyond.

Material and Construction

This flow-through cell is crafted from a combination of black quartz and clear quartz, each selected for its unique optical and protective properties. The black quartz housing serves a crucial purpose — it effectively blocks external light, making the entire unit lightproof and ideal for sensitive UV-Vis and photometric measurements. This ensures that ambient light does not interfere with absorbance or transmission readings, thus maintaining the accuracy and repeatability of your experimental results.

The clear quartz window within the flow cell offers excellent optical transparency across a broad wavelength range, from deep ultraviolet (around 190 nm) to the near-infrared (over 2,500 nm). Quartz is known for its superior thermal stability, chemical resistance, and long-term durability, making it a reliable material even under rigorous laboratory conditions.

An inner tube is integrated into the design, specifically engineered for solvent testing and precise flow control. This feature allows users to perform real-time, in-line analysis of liquids without interrupting the flow, making it highly effective for monitoring reactions, detecting impurities, or measuring concentration changes in dynamic systems.

Key Benefits

• Lightproof Design: The black quartz exterior effectively blocks ambient light, ensuring accurate spectrophotometric readings even in high-light laboratory environments.

• High Optical Clarity: The clear quartz window allows for minimal signal distortion and excellent transmission across UV-Vis and NIR wavelengths.

• Integrated Inner Tube: Enables controlled testing of solvents, supports continuous sample flow, and reduces the risk of cross-contamination between tests.

• Chemical Resistance: Quartz construction resists a wide range of solvents, acids, and bases, supporting long-term, high-performance use.

• Easy Integration: Standardized fittings make it compatible with most flow-through spectroscopic systems and laboratory equipment.

Applications

The Lightproof Flow-Through Cell is versatile and ideal for a wide range of applications that require high-sensitivity, flow-based measurements. Typical uses include:

• Process Monitoring: Continuously measure chemical concentrations or reaction progress in real-time within manufacturing or research settings.

• Pharmaceutical Analysis: Monitor dissolution tests, API concentrations, or formulation stability.

• Environmental Testing: Real-time water quality analysis, including detection of pollutants, contaminants, or chemical residues.

• Biotechnology and Life Sciences: Analyze biological fluids such as proteins, DNA/RNA solutions, or cell culture media during flow-based procedures.

• Food and Beverage Testing: Evaluate color, clarity, and concentration of liquid food samples under continuous flow conditions.

Because of its enclosed, light-blocking construction and precise internal geometry, this flow-through cell is especially well-suited for experiments involving light-sensitive compounds or samples that must be protected from ambient exposure.
