(VAOB85) 8.5ml Fluorescence Cuvette, Bonded, Lightpath 28mm, 12x30x30 mm, 4 Clear Windows

Description VAOB85 Bonded Quartz Fluorescence Cuvette is a 4-window cuvette with a 28 mm optical path length and an 8.5 ml volume. It features a wide clear wall design, ideal for fluorescence measurements that require side detection and enhanced optical clarity. Bonded fabrication ensures cost-effective construction and good chemical resistance under typical laboratory conditions. Key Features 28 mm optical path length — suitable for high-sensitivity fluorescence and absorbance measurements. 4-window design — allows side detection, enabling fluorescence excitation and emission experiments. Bonded fabrication — provides stable performance for most general laboratory applications. Wide wall geometry — optimized for fluorescence setups with precise optical alignment. Broad wavelength range — 190 – 2500 nm, suitable for UV/VIS and NIR applications. Typical Applications Fluorescence spectroscopy (side detection and excitation). UV/VIS absorbance and transmission studies. Routine lab assays and standard optical experiments. Educational and R&D environments where cost-effective bonded construction is preferred. Bonded Fabrication Notes Bonded fabrication offers cost-effective performance for routine measurements. Not recommended for high-temperature applications or long-term solvent exposure. Bonded seams are more sensitive to aggressive organic solvents compared to fused fabrication. Suitable for aqueous and mild solvent environments.
