Description

VAPM8A – 0.7 mL Micro Stopper Absorption Cuvette (Molded, 2 mm Lightpath, 2 Windows)

The VAPM8A is a molded quartz micro absorption cuvette with a 2 mm optical path length and a 0.7 mL sample volume. It is ideal for UV/VIS absorption spectroscopy involving high-concentration or low-volume samples. The cuvette is designed with 2 optical windows for high-transmission measurements and comes with a PTFE stopper providing basic sealing during routine laboratory use.

Key Features

2 mm optical path length: ideal for high-concentration samples to prevent signal oversaturation.
2 optical windows: optimized for absorbance measurements with high optical clarity.
Micro volume (0.7 mL): reduces sample consumption while maintaining measurement accuracy.
PTFE stopper: provides standard sealing for everyday use (not suitable for anaerobic or pressure-sealed applications).
Molded fabrication: highest quality optical finish with a pathlength tolerance of ±0.01 mm.
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 aggressive organic solvents including toluene and acetone; not suitable for HF.
Secure packaging: foam and bubble wrap; drop-tested from 1 meter before shipment.

Typical Applications

UV/VIS absorption spectroscopy
High-concentration sample analysis
Low-volume absorbance testing
Routine laboratory measurements

About Molded Fabrication

Molded fabrication represents the highest optical and dimensional quality among quartz cuvettes.
Manufactured from a single piece of high-purity quartz for maximum precision and durability.
Pathlength tolerance: ±0.01 mm, ensuring exceptional measurement repeatability and accuracy.
Excellent resistance to acids, bases, and strong organic solvents (e.g., toluene, acetone); not compatible with HF.
Superior surface flatness and clarity ideal for precision spectroscopic analysis.

Note: VAPM8A is a precision-molded absorption cuvette designed for high-accuracy measurements in demanding laboratory environments. The PTFE stopper provides standard sealing but is not designed for anaerobic or high-pressure use.

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.
