Adapters for small volumetric flow quantities are specialized components used in industries requiring precise flow measurement and control, such as pharmaceuticals, biotechnology, and chemical processing. These adapters are typically produced by industrial equipment manufacturers, including companies like Swagelok (USA), Parker Hannifin (USA), and Festo (Germany), which are known for their high-quality fluid and gas handling systems. The products include miniature tube fittings, connectors, and flow control devices designed for low-flow applications. These adapters ensure leak-tight connections and accurate flow regulation in sensitive processes.
