Description VNE084 – Quartz Reflection Cuvette, 45 × 12 mm, Bonded Fabrication, All Clear Walls The VNE084 is a cost-effective quartz reflection cuvette designed for reflectance, scattering, and fluorescence measurements in the UV/VIS range (190–2500 nm). Featuring a cylindrical shape with all clear walls, it enables multi-angle illumination and detection, making it ideal for reflection geometry and general analytical applications. Constructed with bonded fabrication, this cuvette is designed for use with aqueous samples and mild conditions. Bonded cuvettes offer fast turnaround time and affordability, making them well suited for routine laboratory use. However, they are not recommended for aggressive organic solvents or strong corrosives. Chemical Compatibility Bonded quartz cuvettes are suitable for aqueous and mild chemical environments. ✔ Compatible: water, buffer solutions, mild acids and bases. ⚠ Limited compatibility with weak organics and alcohols (short exposure only). ❌ Not compatible with aggressive organic solvents such as toluene, acetone, chloroform, MEK, or HF. Key Features Quartz reflection cuvette: designed for reflectance and scattering experiments. Bonded fabrication: low cost and fast lead time for aqueous applications. All clear walls: suitable for multi-angle optical measurements. Open-top design: easy to fill, clean, and handle. UV/VIS transmission range: 190–2500 nm.
