(VAOF178) 17ml Absorption Cuvette, Fused, Lightpath 8mm, 57x43x10.5 mm, 2 Clear Windows

Description VAOF178 Fused Quartz Absorption Cuvette is a 2-window cuvette with an 8 mm optical path length and a 17 ml volume. It features a wide clear wall design, ideal for UV/VIS absorbance measurements where shorter path lengths are preferred for handling higher-concentration samples. Fused fabrication ensures superior thermal stability and excellent chemical resistance, making it well-suited for demanding laboratory environments. Key Features 8 mm optical path length — ideal for medium to high concentration absorbance measurements. 2-window design — optimized for standard straight-beam UV/VIS spectroscopy. Fused fabrication — high thermal resistance up to 600 °C and chemical durability for most acids and bases. Wide wall geometry — supports stable optical transmission with minimal background interference. Broad wavelength range — 190 – 2500 nm, suitable for UV/VIS and NIR applications. Typical Applications UV/VIS absorbance and transmission studies. Quantification of concentrated samples or strong absorbers. Protein and nucleic acid measurements at 260/280 nm. Environmental and chemical analysis. Quality control in R&D and production labs. Fused Fabrication Notes Fused fabrication offers excellent temperature and chemical resistance. Not suitable for hydrofluoric acid (HF) or strong organic solvents like toluene and acetone. Powder seams may discolor with some samples but do not affect performance. Typical path length tolerance is ±0.06 – 0.08 mm.
