    Applications

    DALL-E geothermal energy extraction illustration

    Verify flow and optimize carrier gas control in gas chromatography

    Enable full system stability. Fluctuations in flow rate disrupt the detection of chemical compounds. Tightly regulate carrier gas flow rate to ensure accurate compound detection, using a BASIS electronic mass flow controller.

    Glass manufacturing requires high precision mass flow controllers

    Ensure consistent batches in glass production

    BASIS mass flow devices are used in burner control applications to control gases that heat the glass and facilitate drawing. Scripting and electronic control make your process repeatable and precise. Great for production of lab-quality and other high-volume, low-variability glass.

    Bioprocessing mass flow controller

    Lowering cost and increasing speed of biologics production

    Ensure your process is repeatable and scalable.  BASIS provide accurate and responsive gas flow with a large turndown ratio and integrated gas selection.  The number of spares required is reduced without sacrificing performance.

    mixing fluids

    Gas mixing in molar ratios

    Use BASIS mass flow controller’s intuitive serial commands to make gas mixtures in molecular proportions, and stop paying premiums for custom mixes.
