Description

VFSM05 Quartz Cuvette with Tube is a precision-molded quartz cuvette designed for high-sensitivity fluorescence and absorbance measurements. It features a 5 mm optical path length, 4 clear windows, and a screw cap with a long spout tube, providing excellent sealing performance and convenient fluid handling for continuous or manual sampling.

The molded fabrication process ensures ultra-smooth inner surfaces and high dimensional accuracy (±0.01 mm), enabling stable and repeatable measurements. Compared with bonded and fused fabrication, molded cuvettes offer superior surface quality, excellent chemical resistance (except HF), and high temperature tolerance — making them ideal for demanding research and industrial applications.

Key Advantages

5 mm optical path length — optimized for fluorescence and absorbance applications.
Screw cap with long spout — easy sample injection and excellent sealing to prevent evaporation or contamination.
4 clear optical windows — support for side or axial detection configurations.
Molded fabrication — high precision, smooth surfaces, and stable geometry.
Excellent UV/VIS transmission range (190–2500 nm).

Molded Fabrication Features

High path length accuracy (±0.01 mm).
Excellent resistance to acids, bases, and most organic solvents (except HF).
Thermal stability: up to 1200 °C (short-term) / 600 °C (long-term).
Clean, smooth optical surfaces minimize background and signal noise.
Extended service life compared with bonded and fused types.

Typical Applications

Fluorescence spectroscopy
Absorbance and kinetic assays
Flow or static sampling systems
Biotechnology, pharmaceutical, and chemical analysis

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.
