(VAOF275) 27.5ml Absorption Cuvette, Fused, Lightpath 10mm, 57x54x14 mm, 2 Clear Windows

Description VAOF375 Fused Quartz Absorption Cuvette is a 2-window cuvette with a 15 mm optical path length and a 37.5 ml volume. It features a wide clear wall design, making it ideal for UV/VIS absorbance measurements that require enhanced sensitivity and increased sample volume. Fused fabrication provides excellent chemical and thermal resistance, suitable for demanding analytical and research applications. Key Features 15 mm optical path length — increases detection sensitivity for low-concentration analytes. 2-window design — optimized for straight-beam UV/VIS absorbance measurements. Fused fabrication — excellent thermal resistance (up to 600 °C) and strong chemical durability. Wide wall geometry — ensures stable optical performance and low background interference. Broad wavelength range — 190 – 2500 nm, suitable for UV/VIS and NIR applications. Typical Applications UV/VIS absorbance and transmission studies with enhanced path length. Trace detection of analytes at low concentrations. Environmental and water quality analysis. Protein and nucleic acid measurements at 260/280 nm. High-sensitivity chemical and pharmaceutical assays. Fused Fabrication Notes Fused fabrication provides excellent chemical and thermal resistance. 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 optical performance. Typical path length tolerance is ±0.06 – 0.08 mm.
