Description
VAOF190 Fused Quartz Long Path Absorption Cuvette is a 2-window quartz cuvette with a 34 mm optical path length and a 19 ml volume.
Its long-path design makes it particularly suitable for trace-level absorbance measurements, significantly improving signal sensitivity for low-concentration samples.
Why Long Path Length Matters
A longer optical path length increases the interaction distance between light and the sample, amplifying weak signals and improving the signal-to-noise ratio.
This makes it possible to detect trace analytes with higher accuracy and extend the dynamic measurement range—an essential factor in environmental monitoring, biochemical analysis, and material research.
This cuvette is ideal for:
- Low-concentration or trace-level absorbance analysis
- Environmental contaminant detection (e.g., nitrates, phosphates, organic pollutants)
- Biological and chemical assays requiring enhanced sensitivity
- Research where signal strength and reproducibility are critical
Key Features
- 34 mm optical path — long path length increases absorbance sensitivity.
- 2-window design — optimized for transmission and absorbance spectroscopy.
- Fused fabrication — excellent chemical resistance and can be heated up to 600 °C.
- Wavelength range — 190–2500 nm, suitable for UV/VIS applications.
Typical Applications
- Environmental water analysis (e.g., nitrate, phosphate, heavy metals)
- Biochemical assays requiring higher detection sensitivity
- Pharmaceutical and material science research
- Trace contaminant monitoring and extended signal measurement
Fused Fabrication Notes
- Fused quartz ensures superior clarity, thermal stability, and chemical durability.
- Not suitable for hydrofluoric acid (HF) or strong organic solvents such as toluene and acetone.
- Powder seams may discolor over time but do not affect performance.
- Typical path length tolerance: ±0.06–0.08 mm.
