And with a PTFE screw cap included, it’s easy to keep your sample secure and away from any outside contaminants during the experiment. With its direct benefit focus, this cuvette is perfect for laboratory professionals who demand accuracy and efficiency in their work.

Why screw cuvettes?

Screw cuvettes offer several advantages over other types of cuvettes. One key advantage is that they are less prone to leaking, which can be particularly important when working with volatile or corrosive samples. Additionally, screw caps provide a secure and tight seal that helps to prevent evaporation and contamination of the sample. This can be particularly important when working with small volumes of samples or when conducting experiments over a longer period of time. Finally, screw cuvettes are generally easier to use and require less force to open and close than other types of cuvettes, making them a more user-friendly option for researchers and scientists.

UV Quartz Glass Cuvettes

Most of our quartz cuvettes are made from ES quartz material, absorption onset occurs below 190 nm and there are no absorption bands situated between 190 nm and 250 nm. Exceptionally high transmittance across the UVB, UVA, visible spectrum, and near IR. The transmission spectra for our UV quartz cells can be seen below. When working in the IR spectra, especially for wavelengths greater than 2000 nm, we recommend IR Quartz Glass Cuvettes instead, as they offer high transmission for these wavelengths.

IR Quartz Glass Cuvettes

Made from IR quartz material, absorption onset occurs below 260 nm with exceptionally high transmission across UVB, UVA, visible, near IR, and notably short IR. Transmission drops significantly in the mid-IR, and at 4200 nm there is complete absorption.

Why Aireka Scientific Cuvettes and Cells?

Aireka Scientific Co Limited is world-renowned as the producer of premium quartz cuvettes. Over twenty years of experience manufacturing quartz cuvettes ensures that every cuvette is manufactured to the most exacting standards for reproducible results.

  • Spectrophotometry cuvettes - Most spectrophotometry applications in the visible and UV ranges benefit from Aireka Scientific spectrophotometry cuvettes. Our cuvettes made of ES quartz material deliver precise and reliable readings even at wavelengths as low as 190 nm. The stock cuvettes are compatible with most spectrophotometers and photometers with standard 0.2 - 100 mm path lengths.
  • Fluorimetry cuvettes - Aireka Scientific brings two decades of experience molding high-quality fluorescence cuvettes to new four-sided clear cuvettes for fluorimetry. Available in standard quartz material with ultra-low auto-fluorescence for the highest precision measurements.
  • Protective packaging - Our cuvettes are in dust-free, low scratching-expanded polystyrene packaging. This ensures that premium cuvettes arrive in the laboratory in 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 micro to macro semi-micro sizes to respond to the needs of most scientific applications. We can also customize sample volume to deliver consistent, accurate findings.
  • Perform consistently - The 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.
