Description

Brand: Qvarz | Product Type: Quartz Flow Through Cuvette | MPN: VALB64

The VALB64 Quartz Flow Cuvette is a bonded fabrication cuvette with a 20 mm optical path length and 64 μL sample volume.
Its black wall design effectively reduces stray light and internal reflections, significantly improving signal-to-noise ratio for trace and low-concentration absorbance measurements.
This cell features stainless steel inlet and outlet tubes, providing excellent chemical resistance and secure integration into flow analysis systems.

Key Features

20 mm long optical path for high-sensitivity UV/VIS absorbance measurements
64 μL low-volume design minimizes sample use
Black wall design improves detection sensitivity and accuracy
Stainless steel tubing connectors for durability and chemical resistance
Excellent UV/VIS transmittance from 190–2500 nm
Bonded fabrication for fast, cost-efficient customization

Typical Applications

Trace-level UV/VIS absorbance spectroscopy
Environmental monitoring and water analysis
Flow injection analysis (FIA)
OEM analytical and process monitoring instruments

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.
