Description
VAOF20B Fused Quartz Macro Cuvette is a 7 ml capacity large cuvette designed for UV/VIS absorbance measurements with a 10 mm optical path length.
Its clear two-window design ensures high light transmission and compatibility with standard spectrophotometers, making it a reliable choice for routine laboratory use.
Key Features
- 10 mm path length — standard for most UV/VIS spectrophotometers, ensuring excellent compatibility and reliable measurement results.
- 7 ml volume — ideal for medium sample capacity with good signal stability and reproducibility.
- Fused quartz construction — provides outstanding UV transparency (190–2500 nm), high temperature resistance up to 600 °C, and chemical stability (except HF and certain strong organics).
- 2 clear optical windows — designed for accurate transmission and absorbance testing.
- Manufactured with tight dimensional tolerances for precise optical alignment.
Typical Applications
- Routine UV/VIS absorbance assays
- Biological and chemical analysis
- Environmental testing and water quality monitoring
- R&D and quality control laboratories
Fused Fabrication Notes
- Not suitable for HF and strong organic solvents (e.g., toluene, acetone).
- Powder seams may discolor over time without affecting optical accuracy.
- Dimensional tolerance: typically ±0.06–0.08 mm.
