    Addressing scaling challenges of bioreactor sparging using mass flow control

    Addressing scaling challenges of bioreactor sparging using mass flow control This article was originally published in Fluid Handling Pro on June 29, 2021. Read the original article here. Bioreactor sparging systems are designed to introduce oxygen to feed cell cultures, while removing carbon dioxide to prevent toxic buildup. Various bioreactor features and components are critical to […]

    High accuracy, low-flow color dosing with Coriolis mass flow meters

    High accuracy, low-flow color dosing with Coriolis mass flow meters Many liquid laundry detergents are easily recognized by their distinct blue color. The addition of such blue coloring and other fluorescing agents adds trace amounts of dye to fabrics, both counteracting discoloration and improving brightness. Challenge: Inaccurate, inefficient pumps lead to noticeable variation Modern blue […]

  • Maintaining cryogenic temperatures with pressure control

    Maintaining cryogenic temperatures with pressure control Cryogens are substances that liquefy at or below 120 K under standard pressure (760 Torr). They are commonly used in applications to keep liquefied substances at extremely cold temperatures, including cryopreservation, rocket propulsion, and medical imaging. Two of the most well-know cryogens are liquid nitrogen and helium. Liquid nitrogen […]

    Biosphere 2 studies the impacts of drought on tropical rainforests using flow measurement

    Biosphere 2 studies the impacts of drought on tropical rainforests using flow measurement As the Earth’s climate changes, scientists expect that a hotter, drier world will have severe impacts on global ecosystems, with many areas subjected to increased water stress and/or drought. However, it is difficult to forecast the specific impact climate change will have […]

    Aerating chocolate using mass flow control

    Aerating chocolate using mass flow control Aerated chocolate is increasingly popular because of its particular mouthfeel: bubbles in the chocolate make it lighter, with a unique texture. An aerated chocolate bar has more surface area than a standard chocolate bar, which is why it melts faster in your mouth, intensifying its taste. How are bubbles […]

    Controlling carbon dioxide sparging in brewing applications

    Controlling carbon dioxide sparging in brewing applications Beer is the beverage of choice for billions of people around the world. Whether ale, lager, or stout, carbon dioxide sparging is the process by which beer gets carbonated – making it the not-so-subtle difference between a refreshing pint and a flat disappointment. The average beer drinker is […]
