Why choose a flow cell with screw caps?

Choosing a flow cell with screw caps offers several advantages for your spectroscopic experiments. Here are some key reasons why you should consider flow cells with screw caps:

  1. Secure Seal: Flow cells with screw caps provide a secure and reliable seal. The screw caps tightly seal the cuvette, preventing any sample leakage during measurements. This ensures the integrity of your experiment and minimizes the risk of contamination.
  2. Easy Sample Loading: Screw caps make it convenient to load and unload samples into the flow cell. The caps can be easily opened and closed, allowing for efficient sample handling and reducing the chances of spills or errors.
  3. Sample Protection: The screw caps offer an extra layer of protection for your samples. They act as a barrier, shielding the sample from external factors that could potentially alter its composition or properties. This is particularly beneficial when working with sensitive or reactive samples.
  4. Cleaning and Maintenance: Flow cells with screw caps are easier to clean and maintain compared to other types of cuvettes. The caps can be removed, providing better access to the cuvette chamber for thorough cleaning. This ensures the removal of any residue or contaminants, maintaining the accuracy and reliability of your measurements.
  5. Versatility: Flow cells with screw caps are versatile and compatible with various experimental setups. The screw caps are often designed to fit standard threads, allowing for easy integration with different spectroscopic instruments. This compatibility enhances the flexibility and usability of the flow cell across different laboratory setups.

By choosing flow cells with screw caps, you can enjoy the benefits of a secure seal, easy sample handling, sample protection, convenient cleaning, and compatibility with different instruments. These advantages contribute to more reliable and efficient spectroscopic measurements, ensuring accurate and meaningful results for your research.

What’s the use of flow cells?

Flow cells have a wide range of applications in scientific and laboratory settings due to their unique design and functionality. Here are some key uses of flow cells:

  1. Spectrophotometry: Flow cells are commonly employed in spectrophotometry, where they enable the measurement of absorbance or transmittance of light through a sample. By passing the sample through the flow cell, researchers can obtain valuable information about the composition, concentration, and properties of the sample.
  2. Chemical Analysis: Flow cells are instrumental in various chemical analysis techniques, such as liquid chromatography and flow injection analysis. These techniques involve the continuous flow of a sample through the flow cell, allowing for real-time monitoring and detection of analytes.
  3. Biological Research: Flow cells find extensive use in biological research, particularly in applications such as cell counting, cell culture monitoring, and enzyme kinetics. The controlled flow of biological samples through the flow cell enables researchers to study cellular processes, perform viability assessments, and analyze enzymatic reactions.
  4. Flow Cytometry: Flow cells are integral components of flow cytometers, powerful instruments used for cell analysis and sorting. In flow cytometry, cells suspended in a fluid are passed through the flow cell one at a time, allowing for the characterization and sorting of cells based on their physical and biochemical properties.
  5. Microfluidics: Flow cells play a crucial role in microfluidic systems, which manipulate small volumes of fluids for various applications. Microfluidic flow cells enable precise control of fluid flow, mixing, and reactions, making them valuable tools in fields such as drug discovery, genomics, and diagnostics.
  6. Environmental Monitoring: Flow cells are utilized in environmental monitoring systems to analyze water quality, detect pollutants, and assess the health of ecosystems. By continuously flowing water samples through flow cells, researchers can monitor parameters such as dissolved oxygen, nutrient levels, and pollutant concentrations.

The use of flow cells offers several advantages, including:

  • Real-time Monitoring: Flow cells facilitate continuous and real-time monitoring of samples, enabling researchers to capture dynamic changes and obtain immediate results.
  • Sample Conservation: Flow cells require only small sample volumes, making them suitable for applications where sample conservation is crucial, such as precious or limited sample scenarios.
  • Repeatability and Precision: Flow cells provide consistent and repeatable measurements, ensuring reliable and accurate data acquisition.
  • Flexibility and Customization: Flow cells come in various sizes, pathlengths, and designs, allowing for customization to suit specific experimental requirements.

In summary, flow cells are versatile tools that enable the controlled flow of samples, facilitating a wide range of scientific analyses, measurements, and experiments. Their applications span across disciplines such as chemistry, biology, biotechnology, environmental science, and more, making them indispensable in research and laboratory settings.

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.
