Description

VFPFS4 – 1.4 mL Semi-Micro Quartz Cuvette (Fused, 4 mm Width, 4 Windows, Stopper)

The VFPFS4 is a high-performance semi-micro quartz cuvette designed for fluorescence spectroscopy.
With a narrow 4 mm internal width, 4 optical windows, and a PTFE stopper, it is ideal for sensitive fluorescence measurements with medium sample volumes.
This model is manufactured using fused fabrication, allowing for exceptional thermal and chemical stability.

Key Features

Sample volume: 1.4 mL, suitable for semi-micro fluorescence experiments.
4 optical windows: enable right-angle fluorescence detection.
Fused fabrication: assembled with quartz powder, ensuring high thermal resistance up to 600 °C (1112 °F).
Excellent optical precision: path length tolerance ±0.06 – 0.08 mm.
PTFE stopper: prevents evaporation and contamination during measurement.
Wavelength range: UV/VIS (190 – 2500 nm).

Typical Applications

Fluorescence spectroscopy
Absorbance and transmission measurements
Biochemical and pharmaceutical analysis
Environmental and chemical research

About Fused Fabrication

Fused quartz cuvettes are manufactured by sintering quartz powder at high temperature, providing:

Excellent thermal resistance up to 600 °C (1112 °F).
High UV transparency and optical stability.
Precise optical path length tolerance of ±0.06 – 0.08 mm.

However, fused fabrication has some usage considerations:

Joints may stain or discolor over time with sample exposure.
Not recommended for long-term sample storage.
Not suitable for hydrofluoric acid (HF) and aggressive organic solvents such as toluene and acetone — using these can significantly shorten cuvette lifetime.

Note: For experiments involving aggressive solvents or extended storage, molded quartz cuvettes offer greater durability and chemical 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.
