Description

VFSMF5 – 1.75 mL Sealable Fluorescence Cuvette (Molded, 5 mm Lightpath, 4 Windows, Flat Base)

The VFSMF5 is a molded quartz fluorescence cuvette with a 5 mm optical path length and a 1.75 mL sample volume. It features 4 optical windows and a flat base, making it ideal for fluorescence spectroscopy requiring side detection and stable positioning. The screw cap with septa provides effective sealing for basic anaerobic and oxygen-sensitive experiments.

Key Features

5 mm optical path length: ideal for moderate to high concentration fluorescence measurements.
4 clear windows + flat base: optimized for stable cuvette placement and right-angle fluorescence detection.
Screw cap with septa: reduces sample evaporation and oxygen interference during measurement.
Optional center-hole cap: available for sterile injections.
Molded fabrication: highest optical precision with pathlength tolerance of ±0.01 mm.
Wavelength range: 190–2500 nm (UV/VIS).
Temperature resistance: −60 °C (−76 °F) to 1200 °C (2192 °F).
Chemical compatibility: resistant to most acids, bases, and strong organic solvents (including toluene and acetone); not suitable for HF.
Secure packaging: foam and bubble wrap; drop-tested from 1 meter before shipment.

Typical Applications

Fluorescence spectroscopy
Excitation–emission studies
Medium to high concentration sample analysis
Sealed measurements with reduced oxygen exposure
Stable positioning for long measurement cycles

About Molded Fabrication

Molded fabrication ensures excellent dimensional precision and optical performance.
±0.01 mm pathlength tolerance guarantees high repeatability and stable fluorescence measurements.
Outstanding resistance to most acids, bases, and aggressive organic solvents (e.g., toluene, acetone); not compatible with HF.
Flat base provides improved stability during long measurement cycles.

Note: VFSMF5 is a precision-molded flat-bottom cuvette designed for fluorescence applications that require stable placement and sealing. The screw cap with septa is intended for standard sealing, not for high-pressure or gas-tight use.

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.
