Description

VNE063 – 0.7 / 3.5 mL Quartz Fluorescence Cuvette with PTFE Valve (2 & 10 mm Lightpath, 4 Windows, Molded Fabrication)

The VNE063 is a high-performance quartz cuvette equipped with a screw-threaded PTFE valve, designed for advanced fluorescence and absorbance measurements involving volatile, anaerobic, or reactive samples.
This cuvette features dual optical path lengths of 2 mm and 10 mm, offering exceptional flexibility for both high-concentration and standard measurements. With 4 optically clear windows, it is ideal for right-angle fluorescence detection, absorbance spectroscopy, and specialized gas–liquid applications.

Constructed using molded fabrication, this cuvette provides the highest precision and chemical resistance. Molded quartz cuvettes are one-piece structures without bonded seams, ensuring durability and compatibility with strong acids, bases, and aggressive organic solvents. The PTFE threaded valve (M10) enables precise sealing and sample handling, making it suitable for controlled environments such as inert gas purging or sealed reactions.

Chemical Compatibility

Molded quartz cuvettes exhibit excellent chemical resistance and long service life in harsh laboratory environments.

✔ Compatible with strong acids and bases (except HF), alcohols, aqueous solutions, and most organic solvents.
✔ Excellent resistance to aggressive solvents such as toluene, acetone, MEK, chloroform, and carbon tetrachloride.
❌ Not compatible with hydrofluoric acid (HF).
Durable for long-term use in anaerobic and chemically reactive conditions.

Key Features

Dual optical path lengths (2 mm & 10 mm): allows both high-concentration and standard measurements in a single cuvette.
PTFE threaded valve (M10): enables sealing for inert gas purging, controlled reactions, or anaerobic sample handling.
4 optical windows: ideal for right-angle fluorescence and absorbance measurements.
Molded fabrication: superior chemical durability and high optical precision (±0.01 mm).
Quartz material: UV/VIS transmission range of 190 – 2500 nm.
Available volumes: 0.7 mL (2 mm) and 3.5 mL (10 mm).

Typical Applications

Fluorescence spectroscopy (right-angle detection)
Gas or liquid handling under controlled or sealed conditions
Absorbance measurements with variable path length
Photochemical and kinetic studies
Biochemical and environmental analysis

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.
