Description

VFOB45 Sub Micro Fluorescence Cuvette is a precision-engineered all-black bonded quartz cuvette with a 3 mm optical pathlength and a 45 µL sub-micro volume. This cuvette design combines excellent sensitivity with low background interference, making it ideal for fluorescence and absorbance measurements requiring small sample sizes.

Key Features

45 µL working volume minimizes sample use without sacrificing measurement quality.
3 mm pathlength supports higher signal detection in low concentration fluorescence assays.
All-black walls deliver excellent stray light suppression and improved signal-to-noise ratio.
3 optical windows allow for precise excitation and emission geometry.
Bonded fabrication ensures dimensional precision and long-term sealing stability.

Typical Applications

Fluorescence spectroscopy for low-volume samples
Protein, DNA/RNA, and dye quantification
Life science and biomedical trace-level assays
High-sensitivity kinetic and screening measurements

Bonded Fabrication Notes

Light path tolerance: ±0.06 – 0.08 mm
Bonded seams for optimal optical clarity and tight sealing
Not compatible with HF or strong organic solvents

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.
