(VCOF20Q) 3mL Custom Cuvette, 5 Windows, quartz cover, Fused, Lightpath 20mm, 8.5x21x21 mm

Description VCOF20Q Fused Quartz Cuvette is a precision-engineered 5-window cuvette with a 20 mm optical path length and 3 ml sample volume. This custom-designed cell is optimized for fluorescence spectroscopy, particularly in applications where a low profile and high optical clarity are required. Key Features 20 mm optical path — improves measurement sensitivity for fluorescence and absorbance experiments. 5-window configuration — ideal for side and right-angle fluorescence detection. Ultra-low height (8.5 mm) — reduces sample volume while maintaining standard optical path length, perfect for precious or limited samples. Fused quartz construction — withstands high temperatures (up to 600 °C) and offers broad chemical compatibility, except with HF and certain strong organic solvents. High transmittance from 190–2500 nm for UV/VIS/NIR measurements. Typical Applications Fluorescence and absorbance spectroscopy with limited sample volume. Biochemical and molecular assays with side detection. High-sensitivity analytical work in environmental and life science research. Custom instrument integration and micro-sample testing. Fused Fabrication Notes Can be heated to 600 °C without deformation. Assembled with quartz powder — minor discoloration may occur when exposed to strong dyes or solvents. Not intended for long-term sample storage. Not compatible with HF, toluene, acetone, or other strong organic solvents, as these may shorten the cuvette lifespan.
