VNE021 – 1.4 mL Semi-Micro Quartz Cuvette with PTFE Stopper (Fused, 2 Windows, 4 mm Width)

The VNE021 semi-micro cuvette is a high-precision fused quartz cell designed for UV/Vis absorption spectroscopy. With a 10 mm optical path length and a 1.4 mL sample capacity, it offers excellent optical clarity and chemical durability. The narrow 4 mm inner width helps minimize sample consumption while maintaining measurement accuracy. A PTFE stopper provides a secure seal, reducing evaporation and contamination during sensitive experiments.

Key Features

📏 10 mm optical path length, compatible with most UV/Vis spectrophotometers.
💧 1.4 mL volume with narrow 4 mm width for efficient sample use.
🌈 High-purity fused quartz for superior UV transparency (190–2500 nm).
🧪 PTFE stopper provides tight sealing to minimize evaporation.
🧼 Fused fabrication ensures high precision, durability, and excellent temperature resistance.

QVARZ Cuvettes Transmission Characteristics The following table is our cuvettes and cells made of quartz material suitable for wavelength from 190nm to 2500nm and depicts the percentage transmission for the material. 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. Perform consistently - QVARZ Cuvettes are constructed from high-quality fused quartz materials and are grouped by manufacturing mold cavities to ensure the lowest fluctuation in extinction coefficient. Customization - Custom cuvettes and cells are encouraged and available upon request; mechanical drawings with specifications and tolerances are prerequisites. Awesome pricing and flexibility on small quantities.
