Ferrule

Ferrules are small but crucial components in various analytical and laboratory instruments, particularly chromatography systems. Typically made of materials like stainless steel, PEEK (polyetheretherketone), or graphite, ferrules serve as compression seals. Their primary function is to secure and create a leak-tight connection between chromatographic columns, tubing, and fittings. By compressing around the tubing, they ensure a consistent and reliable flow of gases or liquids. Ferrules are widely used in high-performance liquid chromatography (HPLC), gas chromatography (GC), and other analytical techniques where precise and reproducible connections are critical to achieve accurate and consistent results. Their durability and ability to withstand high pressures make them invaluable in analytical laboratories.
