Description

VLB140 Flow Cell is a high-capacity quartz flow cell designed for fluorescence spectroscopy and other optical measurement applications requiring stable flow, high sensitivity, and dual path length flexibility. With a 10/40 mm optical path length and an internal volume of 16 mL, it is well suited for medium-to-large volume flow systems and industrial or research environments.

This model uses bonded fabrication — assembled with high-quality optical adhesive to ensure clear light paths and stable structural integrity. Bonded flow cells offer cost-effective customization and are ideal for applications that don’t require extreme thermal or chemical resistance. The cell features OD 8 mm quartz tubing for reliable connection and easy integration with existing flow systems.

Bonded Fabrication Features

Assembled with optical-grade adhesive for fast customization and lower cost.
Good optical transmission with clear and stable flow channels.
Recommended for most water-based and mild chemical solutions (not suitable for strong organic solvents or HF).
Path length tolerance approximately ±0.06–0.08 mm.
Economical solution for large-volume fluorescence and absorbance applications.

Typical Applications

Fluorescence spectroscopy
Flow-through optical detection systems
Water quality monitoring
Environmental and industrial analysis
OEM system integration

Key Features

Dual optical path length (10 mm & 40 mm)
Large 16 mL internal volume
4 clear windows for fluorescence excitation and detection
Quartz OD 8 mm connectors
UV/VIS compatible (190 – 2500 nm)

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.
