Why 2mm Pathlength Cuvettes over 10mm Ones?

2mm pathlength cuvettes are often preferred over 10mm ones for several reasons:

  1. Increased Sensitivity: Due to the shorter path length, 2mm cuvettes require less sample volume and thus offer increased sensitivity for detection. This is particularly useful for expensive or limited sample volumes.
  2. Reduced Sample Dilution: With a smaller path length, 2mm cuvettes allow for a lower dilution of the sample, minimizing potential errors and maximizing the accuracy of the results.
  3. Faster Sampling: The shorter path length of 2mm cuvettes allows for faster sampling and data collection, making them ideal for time-sensitive experiments.
  4. Wider Detection Range: Many 2mm cuvettes can detect in the 200-2500nm spectral range, which is wider than that of many 10mm cuvettes. This makes them a more versatile choice for a range of applications.
  5. Reduced Cost: Since 2mm cuvettes require less sample volume, they can help reduce overall costs associated with sample preparation and analysis.

Overall, 2mm pathlength cuvettes offer several advantages over their 10mm counterparts, making them a popular choice for many applications in the fields of chemistry, biochemistry, and biotechnology.

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.
