Description

VFML50Q Large Molded Quartz Cuvette is a high-volume 4-window cuvette designed for fluorescence and absorbance spectroscopy that requires a long optical path length.
With a 50 mm light path and 125 ml capacity, it is ideal for trace-level detection, reaction monitoring, and large-volume applications. This model comes with a quartz lid that helps reduce evaporation and contamination during measurements.

Key Features

50 mm optical path — provides extended light travel distance, enhancing sensitivity for dilute samples and trace analysis.
4 clear windows — enable primary and side detection, suitable for fluorescence and absorbance measurements.
125 ml capacity — suitable for large volume experiments such as kinetic studies or photochemical reactions.
Quartz cover — reduces evaporation and external contamination (not airtight).
Molded fabrication — ensures high dimensional precision, stable performance, and excellent optical clarity.
Wide transmission range 190–2500 nm covering UV and visible spectroscopy.

Typical Applications

Fluorescence spectroscopy with side or multi-angle detection.
UV/VIS absorbance measurements for low-concentration samples.
Photochemical and kinetic reaction monitoring in bulk samples.
Environmental and process analysis requiring high sensitivity.

Molded Fabrication Notes

Precision molded quartz construction with excellent surface flatness and dimensional accuracy.
Chemically resistant to most strong acids and solvents (except HF).
Compatible with common organic solvents including toluene and acetone.
Durable and easy to clean for long-term laboratory 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.
