Description

VASM95 – 3.5 mL Standard Absorption Cuvette with Inner Screw Cap (Molded, 10 mm Lightpath, 2 Windows)

The VASM95 is a molded quartz absorption cuvette with a 10 mm optical path length and a 3.5 mL sample volume. It features an inner screw cap for improved sealing, making it more secure than a standard PTFE lid. This design minimizes evaporation and is suitable for anaerobic and oxygen-sensitive applications. With molded fabrication, it offers exceptional dimensional accuracy and chemical durability.

Key Features

10 mm optical path length: standard for most UV/VIS spectrophotometers.
2 clear optical windows: optimized for high transmission and accurate absorbance measurements.
Inner screw cap: provides tighter sealing compared to PTFE lids, reducing evaporation and oxygen ingress.
Molded fabrication: top precision with pathlength tolerance of ±0.01 mm, offering the highest optical quality.
Wavelength range: 190–2500 nm (UV/VIS).
Temperature resistance: −60 °C (−76 °F) to 1200 °C (2192 °F).
Chemical compatibility: resistant to most acids, bases, and strong organic solvents including toluene and acetone; not suitable for HF.
Packaging: foam and bubble wrap; drop-tested from 1 meter before shipment.

Typical Applications

UV/VIS absorption spectroscopy
Anaerobic and oxygen-sensitive measurements
Environmental and chemical analysis
Routine laboratory absorbance testing

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.
