Description

VLM24 Flow Through Cell is a high-precision quartz cuvette designed for fluorescence spectroscopy applications that require short path lengths and high measurement stability. It features a 2 mm optical path length and a 700 μL internal volume, making it ideal for high-concentration samples or limited sample volumes in sensitive fluorescence and absorbance measurements.

This cell is manufactured using molded fabrication, offering excellent optical clarity, minimal path length tolerance (±0.01 mm), and superior chemical resistance. With 4 clear windows and quartz tubing connectors (OD 4 mm / ID 2 mm), it enables precise side detection while maintaining easy integration into flow systems.

Molded Fabrication Features

High UV/VIS transmittance from 190 to 2500 nm.
Ultra-tight path length tolerance of ±0.01 mm for stable optical performance.
No adhesives — clean, inert flow channel design.
Excellent resistance to acids, bases, and most solvents (except HF).
Thermal tolerance up to 1200 °C short-term and 600 °C long-term.

Typical Applications

Fluorescence spectroscopy with side detection
Chromatography and flow injection analysis
Life science and bioassay systems
Inline and process monitoring
OEM analytical instruments

Key Features

2 mm optical path length for high-concentration samples
700 μL sample volume
4 optical windows for excitation and emission detection
Quartz tubing connector (OD 4 mm / ID 2 mm)
Molded fabrication for superior optical and mechanical precision

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.
