Description
VALB323 Black-Walled Flow Through Cuvette is a precision quartz cuvette designed for micro-volume absorbance measurements where light control and signal stability are critical. With a 10 mm optical path length and a 32 μL sample volume, this cuvette provides high sensitivity while minimizing sample consumption. The black-walled design suppresses stray light and reflection, enhancing the signal-to-noise ratio, which is especially valuable for low-concentration samples. Screw-type connectors offer a secure and reliable fluid connection for stable continuous flow measurements.
Key Advantages
- Black-walled structure reduces background noise and improves signal quality.
- Micro-volume design minimizes sample use (only 32 μL).
- Continuous flow configuration ensures stable readings and supports inline measurements.
- High transmission and precision across the UV/VIS range (190–2500 nm).
- Screw connectors provide stable and easy integration with fluidic systems.
Fabrication Method Features – Bonded*
- Path length tolerance: ±0.06–0.08 mm.
- Cost-effective and clean fabrication process.
- Recommended for aqueous samples only; not suitable for organic solvents.
- Provides reliable optical performance for routine use.
Typical Applications
- Micro-volume absorbance spectroscopy
- Flow injection analysis and kinetic measurements
- Life science assays with limited sample volumes
- OEM and inline fluidic detection systems
