Description
VAFL30N Fused Quartz Large Cuvette is a 2-window, 30 mm path length cuvette with a large 43 ml internal volume. It is designed for applications requiring higher sample capacity and extended optical path for increased sensitivity, particularly in UV/VIS absorbance spectroscopy. The cuvette is fabricated with fused quartz for excellent chemical and thermal resistance, making it suitable for demanding analytical environments.
Key Features
- 30 mm optical path length — increases absorbance sensitivity, ideal for trace analysis and low-concentration samples.
- 2-window design — optimized for transmission and absorbance measurements with minimal signal loss.
- Fused fabrication — offers high temperature resistance and chemical durability for long-term use.
- Large 43 ml capacity — allows for bulk sampling and extended measurement runs.
- Wide spectral range — 190 – 2500 nm, suitable for UV, visible, and NIR applications.
Typical Applications
- UV/VIS absorbance spectroscopy.
- Trace-level detection with extended path length.
- Environmental, chemical, and industrial monitoring.
- Experiments requiring large sample volume and stable optical alignment.
Fused Fabrication Notes
- High temperature resistance up to 600 °C (1112 °F).
- Excellent resistance to most acids, bases, and solvents (excluding HF, toluene, acetone, and other aggressive organics).
- Powder seams may discolor with long-term storage; not intended for extended sample containment.
- No cover — suitable for open-top measurements or setups with external sealing mechanisms.
