Description

VFPFS1 – 0.35 mL Semi-Micro Quartz Cuvette (Fused, 1 mm Width, 4 Windows, with Stopper)

The VFPFS1 is a precision semi-micro quartz cuvette specifically designed for fluorescence spectroscopy.
It features a narrow 1 mm internal width and 4 optical windows, making it ideal for low-volume fluorescence measurements with high sensitivity.
Equipped with a PTFE stopper, it allows secure sample handling and minimizes evaporation or contamination.

Key Features

Sample volume: 0.35 mL — ideal for micro- and semi-micro fluorescence assays.
1 mm internal width: enables precise optical measurements with minimal sample volume.
4 optical windows: allows both excitation and emission detection (90° fluorescence measurement).
PTFE stopper: ensures secure sealing and protects against evaporation.
Fused fabrication: made with quartz powder, resistant to temperatures up to 600 °C (1112 °F).
Path length tolerance: ±0.06 – 0.08 mm.
Wavelength range: UV/VIS (190 – 2500 nm).

Typical Applications

Fluorescence spectroscopy (excitation and emission)
Trace analysis with small sample volumes
Biochemical and pharmaceutical R&D
Environmental and chemical detection

About Fused Fabrication

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

Thermal resistance up to 600 °C (1112 °F).
Excellent optical clarity and UV transparency.
Stable path length tolerance (±0.06 – 0.08 mm).

Usage Notes

Fused seams may stain or discolor after repeated use.
Not recommended for long-term sample storage.
Do not use with: hydrofluoric acid (HF), toluene, acetone, or other aggressive organic solvents, which can shorten the cuvette’s lifespan.

Note: For experiments involving aggressive solvents or extended storage, molded quartz cuvettes offer better 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.
