Description VNE085 – Quartz Reflection Cuvette, 45 × 12.5 mm, Fused Fabrication, All Clear Walls The VNE085 is a precision-engineered quartz reflection cuvette designed for UV/VIS (190–2500 nm) optical applications involving reflectance, scattering, and surface interaction measurements. Unlike standard transmission cuvettes, this specialized design features a cylindrical body with all clear walls, making it ideal for experiments that rely on reflected light or multi-angle detection geometries. Constructed using fused fabrication, this cuvette is resistant to a wide range of chemicals, including strong acids, bases, and many organic solvents. The fused structure ensures high durability, chemical resistance, and long service life, making it suitable for demanding analytical and research environments. Chemical Compatibility Fused quartz cuvettes offer excellent resistance to most laboratory chemicals. ✔ Compatible: strong acids and bases, alcohols, most organic solvents (e.g., toluene, acetone, chloroform, carbon tetrachloride). ⚠ Avoid long-term exposure to very aggressive organics to extend cuvette life. ❌ Not compatible with hydrofluoric acid (HF). Key Features Quartz reflection cuvette: designed for reflectance, scattering, and fluorescence experiments. Fused fabrication: high chemical resistance and long service life. All clear walls: excellent optical transmission for multi-angle measurements. UV/VIS transmission: 190–2500 nm wavelength range. Open top design for easy sample handling.
