Description

Brand: Qvarz | Product Type: Quartz Flow Through Cuvette | MPN: VALB300

The VALB300 Quartz Flow Cuvette is a bonded fabrication cuvette with a 5 mm optical path length and 300 μL sample volume, designed for UV/VIS absorption spectroscopy.
The cuvette features a black wall design, which effectively suppresses stray light and side reflections, ensuring higher sensitivity and lower background noise — ideal for trace-level and low-concentration measurements.
Equipped with screw connectors, this cuvette integrates easily into analytical systems for stable flow measurements.

Key Features

5 mm optical path length — suitable for medium to high concentration measurements
300 μL low sample volume design for cost-efficient testing
Black wall construction minimizes stray light and reflections, enhancing signal-to-noise ratio
Improved stability and repeatability in low-concentration and fluorescence applications
Screw connectors ensure secure and leak-free flow integration
Bonded fabrication for fast customization and cost-effective production
Excellent UV/VIS transmittance from 190–2500 nm

Typical Applications

UV/VIS absorption spectroscopy of aqueous samples
Micro-volume and trace analysis
Flow injection analysis (FIA)
Online monitoring and OEM analytical systems

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.
