Description

VFOB05 Ultra Micro Fluorescence Cuvette is an advanced sub-micro volume quartz cuvette with a 2.5 mm optical pathlength and 5 µL sample volume.
Its black wall design minimizes stray light and maximizes signal-to-noise ratio, making it ideal for extremely small sample fluorescence measurements.

Key Features

Ultra-low volume — only 5 µL, perfect for rare, expensive, or precious samples.
2.5 mm short optical pathlength enables high-intensity fluorescence detection with minimal sample consumption.
Black walls effectively suppress background and scattered light.
Three optical windows designed for optimal excitation and emission measurement.
Bonded fabrication ensures precision, durability, and tight sealing.

Typical Applications

Ultra-micro fluorescence spectroscopy
Protein and nucleic acid quantification
Clinical and biochemical micro assays
Trace-level fluorescence measurements

Bonded Fabrication Notes

Precision bonded seams provide stability and excellent optical clarity
Light path tolerance: ±0.06 – 0.08 mm
Not suitable for 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.
