Description

VALB180 Black-Walled Micro Flow Cuvette is a precision bonded quartz flow cell engineered for absorbance measurements with extended 20 mm optical path length. It features a micro-volume chamber of 180 μL and black-walled exterior that effectively suppresses stray light and reflection, significantly enhancing measurement sensitivity. The cell is equipped with stainless steel inlet and outlet tubes for secure fluid connection, making it suitable for automated flow systems and kinetic assays.

Key Features

20 mm long optical path improves sensitivity for low-concentration or weak-absorbance samples.
Black-walled design minimizes stray light interference and background noise, ensuring high measurement precision.
Micro-volume capacity (180 μL) allows for low sample consumption while maintaining analytical performance.
Stainless steel connectors provide robust, leak-resistant connections suitable for flow applications.
Designed for use in the UV/VIS wavelength range of 190 – 2500 nm.

Typical Applications

Trace concentration detection and kinetic absorbance assays.
Flow analysis and real-time monitoring of chemical or biochemical reactions.
Integration with HPLC, peristaltic pumps, and automated analytical systems.
Low-background measurements in UV/VIS spectroscopy.

Bonded Fabrication Notes

Bonded quartz cuvettes are assembled with optical adhesive to provide strong sealing and precise alignment.
Recommended for aqueous solutions; avoid strong organic solvents or acids that can degrade the bonding layer.
Rinse and clean promptly after each 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.
