(VCOF20-N) 3mL Custom Cuvette, 5 Windows, no cover, Fused, Lightpath 20mm, 8.5x21x21 mm

Description VCOF20-N Custom Fused Quartz Cuvette is a 5-window, 3 ml capacity cuvette designed for specialized fluorescence and UV/VIS spectroscopy applications. With a 20 mm optical path length and a unique compact height of 8.5 mm, it enables high sensitivity measurements in low-profile setups. The fused quartz construction ensures excellent optical clarity and temperature resistance, making it ideal for demanding research environments. Key Features 20 mm optical path — delivers high absorbance sensitivity and enhanced detection for low-concentration samples. 5-window design — allows flexible detection from multiple angles, ideal for fluorescence spectroscopy. Compact profile (8.5 mm height) — suitable for specialized or low-clearance instrument holders. Fused quartz construction — excellent transmission from 190 to 2500 nm and high temperature tolerance up to 600 °C. 3 ml volume — minimizes sample waste while maintaining strong signal intensity for longer path length. Typical Applications High-sensitivity fluorescence and UV/VIS spectroscopy. Low-profile instrument setups requiring short cell height. Photochemical, biochemical, and environmental sample measurements. High optical pathlength measurements with minimal sample volume. Fused Fabrication Notes Constructed using fused quartz powder, ensuring excellent thermal stability and optical precision. Gaps may discolor over time; long-term sample storage in the cell is not recommended. Not compatible with HF, toluene, acetone, or other aggressive organic solvents. High transmission and dimensional accuracy suitable for research-grade measurements.
