Description

VFOFY – 1.75 mL Standard Fluorescence Cuvette (Fused, 5 mm or 10 mm Lightpath, 4 Windows)

The VFOFY is a standard fused quartz fluorescence cuvette with an adjustable optical path length of 5 mm or 10 mm and a 1.75 mL sample volume.
Constructed with Fused Fabrication (assembled with quartz powder), it offers superior optical clarity, excellent chemical resistance, and high temperature durability, making it an ideal choice for a wide range of fluorescence and UV/VIS spectroscopy applications.

Key Features

Flexible path length: 5 mm or 10 mm, suitable for different concentration ranges.
4 clear windows: designed for excitation and emission detection in fluorescence measurements.
Fused fabrication: ensures structural integrity and exceptional light transmission.
Heat resistance: up to 600 °C (1112 °F).
Chemical resistance: resistant to most acids, bases, and solvents, but not compatible with HF, toluene, acetone, or strong organic solvents.
Pathlength tolerance: ±0.06 – 0.08 mm.
Protective packaging: foam and bubble wrap; drop-tested to 1 m before shipment.

Typical Applications

Fluorescence spectroscopy
UV/VIS absorbance measurements
Biological and environmental assays
Pharmaceutical and material science research

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.
