Description

VFOFC44 – 5 × 5 mm Optical Path Micro Quartz Cuvette (Fused, 4 Windows, Open Top)

The VFOFC44 is a custom fused quartz cuvette featuring a 5 × 5 mm optical path and four clear windows, designed for fluorescence and absorption measurements that require high optical quality and flexibility. Its compact internal volume of 875 μL makes it ideal for small to medium volume experiments while maintaining excellent measurement precision.

Key Features

5 × 5 mm optical path: provides balanced sensitivity and sample economy.
Four clear windows: designed for fluorescence experiments with side detection.
Fused fabrication: withstands temperatures up to 600 °C (1112 °F), ensuring excellent UV/VIS optical clarity.
Quartz powder assembly: seams may stain with prolonged exposure; not recommended for long-term storage.
Chemical compatibility: resistant to most acids and bases, but not compatible with HF, toluene, acetone, or other strong organic solvents which can shorten its lifespan.
Pathlength tolerance: ±0.06 – 0.08 mm.
Wavelength range: UV/VIS (190 – 2500 nm).
Customizable for shorter path lengths (4×4, 3×3, 2×2 mm).

Typical Applications

Fluorescence spectroscopy with side detection
Small-volume biochemical and environmental measurements
Pharmaceutical and analytical research
Custom optical setups requiring high UV transparency

About Fused Fabrication

Fused quartz cuvettes are manufactured through high-purity quartz powder sintering, offering:

High temperature resistance up to 600 °C (1112 °F)
Excellent UV/VIS optical clarity
Good chemical resistance against most acids and bases
Not suitable for HF, toluene, acetone, and other aggressive organic solvents
Possible seam staining if used for long-term sample storage
Optical path tolerance: ±0.06 – 0.08 mm

Note: For experiments involving aggressive organic solvents or long-term storage, molded cuvettes may offer better durability.

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.
