Description
VNE039 – 22 mL Large Quartz Absorption Cuvette (25 mm Lightpath, 2 Windows, Fused Fabrication)
The VNE039 is a large-volume fused quartz cuvette designed for high-sensitivity absorption measurements. It features a 25 mm optical path length, 22 mL capacity, and two clear optical windows, making it ideal for applications requiring higher sample volumes or enhanced signal detection.
Constructed using fused fabrication, this cuvette provides excellent optical clarity, thermal resistance, and compatibility with most chemical reagents. Its large window size (28 × 38 mm) allows efficient light transmission over an extended path length, improving detection sensitivity for low-concentration samples.
Key Features
- 25 mm optical path length — ideal for enhanced absorbance and sensitivity.
- 22 mL volume — suitable for large-volume analytical applications.
- 2 optical windows — optimized for absorption spectroscopy.
- Fused quartz construction — excellent optical clarity and temperature resistance up to 600 °C.
- Chemical resistance — compatible with strong acids, bases, and most organic solvents (excluding HF and aggressive organics such as toluene and acetone).
- Optional PTFE holder available.
Typical Applications
- UV/VIS absorption spectroscopy
- Environmental and water quality analysis
- Biochemical and pharmaceutical research
- Low-concentration detection and kinetic studies
