Description

VAOBM5 – 1.75 mL Semi-Micro Quartz Cuvette (Bonded, 5 mm Width, 2 Windows, PTFE Lid)

The VAOBM5 is a reliable and cost-effective bonded quartz cuvette designed for UV/VIS absorption spectroscopy. With a 5 mm internal width and a 10 mm optical path length, this cuvette is ideal for medium-to-high sample volume applications where measurement stability and precision are essential. Bonded fabrication offers good optical clarity at an economical cost, making it an excellent choice for routine analytical work.

Key Features

Sample volume: 1.75 mL (1750 µL) — suitable for semi-micro and standard assays.
5 mm internal width: allows for stable optical transmission and improved signal strength.
10 mm optical path length: standard geometry compatible with most spectrophotometers.
2 optical windows: designed for clear and accurate absorption measurements.
Bonded fabrication: ±0.06–0.08 mm path length tolerance for dependable analytical performance.
Chemical resistance: suitable for aqueous solutions and mild solvents (not suitable for HF or strong organic solvents).
Wavelength range: UV/VIS (190–2500 nm).

Typical Applications

UV/VIS absorption spectroscopy
Protein and nucleic acid quantification
General laboratory assays and quality control
Pharmaceutical and biochemical analysis

About Bonded Fabrication

Bonded quartz cuvettes are assembled from precision-ground quartz plates. They provide:

Good optical performance at a lower cost compared to molded or fused types.
Typical path length tolerance of ±0.06–0.08 mm.
Compatibility with aqueous solutions and mild solvents (avoid HF, toluene, acetone, and strong organics).

Usage Notes

Perfect for routine UV/VIS absorption spectroscopy.
Ideal for standard lab solutions and buffers.
Avoid long-term storage with strong organic solvents.

Note: Bonded quartz cuvettes offer dependable optical quality at an economical cost, making them a popular choice for everyday analytical applications.

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.
