Description
VFLB250 Black-Walled 3-Window Micro Flow Cuvette is a high-performance bonded quartz flow cell specifically designed for fluorescence measurements. With a 10 mm optical path length and 250 µL internal volume, it allows efficient sample use while maintaining high sensitivity.
The three-window design enables both excitation and emission detection, making it ideal for fluorescence spectroscopy. The black-walled structure effectively suppresses stray light, improving signal-to-noise ratio and measurement accuracy. Equipped with glass tube connectors, this cuvette supports smooth, low-dead-volume fluid transfer.
Key Features
- Three-window design allows simultaneous excitation and emission detection for fluorescence applications.
- Black-walled construction minimizes stray light and optical crosstalk.
- 10 mm optical path ensures reliable absorbance and fluorescence measurements.
- Micro-volume chamber (250 µL) reduces sample waste while maintaining measurement quality.
- Compatible with UV/VIS (190 – 2500 nm) detection range.
Typical Applications
- Fluorescence spectroscopy with side detection.
- Continuous-flow fluorescence assays.
- Integration with peristaltic pumps or automated sampling systems.
- Low-background kinetic and trace analysis experiments.
Bonded Fabrication Notes
- Bonded quartz construction ensures strong sealing and excellent optical alignment.
- Recommended for aqueous or mild buffer solutions; avoid aggressive solvents and acids that can damage the bonding layer.
- Rinse thoroughly after each use to maintain surface quality and extend cuvette lifespan.
