The 10 mm Liquid Tight Quartz Absorption Cuvette with a 3.5mL chamber volume is the ideal choice for measuring cell absorbance and for optical spectroscopy. This premium product is made from high-performance quartz to ensure maximum durability, meaning you can use it again and again even when working with harsh chemicals.

It offers incredible functionality with an external thread and a PTFE screw cap included and includes two polished windows which allow the light of the spectrophotometer accurately through the cuvette. The round bottom design has a path length of 10 mm providing astoundingly accurate measures possible in wavelengths ranging from 200 – 2500 nm. With its advanced internal construction, this sturdy cuvette guarantees efficient absorption readings – time after time.

What’s the use of cuvettes with screw caps?

Cuvettes with screw caps are the perfect solution for securing samples during testing and storage. These caps offer an airtight seal to help preserve the integrity of each sample. This is especially useful when dealing with volatile, reactive, or contamination-sensitive materials.

There are a variety of applications that can benefit from cuvettes with screw caps. For instance, when you need to store DNA or proteins for longer periods of time, these cuvettes can securely hold onto these compounds. They are equally useful in chemical reactions that take a while and need to avoid contamination. Moreover, these cuvettes can help to contain air or water samples during environmental monitoring to avoid the loss of volatile or reactive compounds. In fact, for virtually any application where a sample needs to remain sealed and intact, cuvettes with screw caps are a great choice.

So, to sum everything up, whether you’re testing enzymes, and proteins or just checking sample purity, cuvettes with screw caps are an indispensable tool.

NoteMolded and fused cuvettes and cells are assembled by direct fusion without the use of adhesives throughout the production process. This guarantees resistance against corrosive chemicals and high temperature. Each quartz cuvette and cell has excellent transmission from 190nm to 2500nm.

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.
