Description

VALB120 Black-Walled Micro Flow Cuvette is a high-sensitivity bonded quartz flow cell engineered for micro-volume absorbance measurements. With a short 2 mm optical path length and only 120 μL internal volume, it enables precise detection of high-concentration or strongly absorbing samples with minimal sample usage. The black-walled exterior effectively suppresses stray light and reflection, ensuring superior measurement accuracy. The cell features screw connectors for secure, leak-free integration with fluid handling systems.

Key Features

Black-walled design reduces stray light and background noise, enhancing signal-to-noise ratio in UV/VIS spectroscopy.
2 mm optical path suitable for high absorbance or concentrated sample measurements.
Micro-volume chamber (120 μL) minimizes sample consumption.
Screw connectors provide tight and stable fittings for reliable flow control.
Optimized for UV/VIS wavelength range from 190 – 2500 nm.

Typical Applications

High-concentration sample absorbance measurements.
Continuous flow analysis and kinetic assays.
Microfluidic and automated biochemical monitoring systems.
Online monitoring in process or research environments.

Bonded Fabrication Notes

Bonded quartz cuvettes are sealed with optical adhesive for strong alignment and leak resistance.
Recommended for aqueous samples; avoid strong organic solvents or acids that may damage the bonding layer.
Rinse and clean immediately after use to maintain optical clarity and extend service life.

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.
