Description

Brand: Qvarz | Product Type: Quartz Flow Through Cuvette | MPN: VALB400S

The VALB400S Quartz Flow Through Cuvette is designed for UV/VIS absorption spectroscopy applications that require stable flow, clean channels, and easy integration into analytical systems. With a 10 mm optical path length and 400 μL sample volume, it provides reliable measurements for aqueous solutions in laboratory and OEM setups. The screw connector design enables secure and leak-free fluid connections.

Bonded Fabrication Features

High UV/VIS transmittance from 190 to 2500 nm
Path length tolerance of ±0.06–0.08 mm ensures dependable optical performance
Clean, adhesive-free flow channel construction
Best suited for aqueous samples (not recommended for organic solvents or strong bases)
Cost-effective and fast manufacturing turnaround

Key Advantages

10 mm standard optical path length for most UV/VIS instruments
400 μL internal volume allows for minimal sample usage
15 mm Z-dimension (optional 8.5 mm or 20 mm) fits common spectrometer beam heights
Screw connectors provide secure, leak-resistant tubing connections
Excellent optical clarity and stable signal for process and laboratory applications

Typical Applications

UV/VIS absorption spectroscopy of aqueous solutions
Micro-volume flow injection analysis (FIA)
Online process monitoring and quality control
OEM detector and analytical system integration

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.
