(VAOF05) 0.5ml Absorption Cuvette, Fused, Lightpath 3mm, 21.5x10x5 mm, 2 Clear Windows

Description VAOF05 Fused Quartz Microvolume Cuvette is a 0.5 ml capacity custom cuvette designed for high-precision absorption spectroscopy with a 3 mm optical path length. Its compact structure (21.5 × 10 mm) and low internal volume make it ideal for micro-volume analysis, OEM instruments, and specialized analytical applications. This model showcases our custom fabrication capabilities, offering exceptional clarity and dimensional precision for laboratories working with small or precious sample volumes. Key Features 3 mm optical path — optimized for short-path absorbance measurements with low sample volumes. 0.5 ml capacity — ideal for micro-volume and high-value sample testing. Custom dimensions — fits specialized and OEM instrument designs. Fused quartz material — excellent UV transparency, thermal stability, and resistance to most chemicals. Broad wavelength range: 190–2500 nm — compatible with UV/VIS/NIR spectroscopic applications. Typical Applications Micro-volume absorption spectroscopy Biochemical and clinical diagnostics High-value or precious sample testing OEM and custom analytical systems Environmental and trace detection Fused Fabrication Notes Fused quartz provides superior optical transmission and thermal stability up to 600 °C. Not suitable for hydrofluoric acid (HF) or aggressive organic solvents such as toluene or acetone. Powder seams may discolor over time but do not impact optical accuracy. Typical dimensional tolerance: ±0.06–0.08 mm.

IR or Glass material is not included. Why QVARZ Cuvettes and Cells?QVARZ is world-renowned as the producer of premium quartz cuvettes. Over fifteen years of experience manufacturing quartz cuvettes ensures that every QVARZ cuvettes are manufactured to the most exacting standards for reproducible results. Spectrophotometry cuvettes - Most spectrophotometry applications in the visible and UV ranges benefit from QVARZ spectrophotometry cuvettes. Our cuvettes made of fused quartz material deliver precise and reliable readings even at wavelengths as low as 190 nm. QVARZ cuvettes are compatible with most spectrophotometers and photometers with standard 0.2 - 100 mm path lengths. Fluorometry cuvettes - QVARZ brings two decades of experience molding high-quality spectrophotometry cuvettes to new four-sided clear cuvettes for fluorometry. Available in standard quartz material with ultra-low auto-fluorescence for the highest precision measurements. Protective packaging - QVARZ cuvettes are encased in dust-free, low scratching expanded polystyrene packaging. This ensures that premium cuvettes arrive in the laboratory ina the same pristine condition they were in at the factory, with optical quality windows and free of contaminants.  Volumes for most purposes - Our cuvettes are available in a variety of ranges from macro to macro semi-micro sizes to respond to the needs of most scientific applications. We are also able to customize sample volume to deliver consistent, accurate findings.
