HPLC Plunger (Different Brands)
Precision Component for Accurate Solvent Delivery in HPLC Pumps
An HPLC Plunger is a critical component of a High-Performance Liquid Chromatography (HPLC) pump. It moves back and forth inside the pump head to precisely deliver the mobile phase solvent at high pressure through the system. The plunger is typically made from sapphire, ceramic, or stainless steel to ensure high durability, chemical resistance, and smooth operation. Its accurate movement maintains consistent flow rate and pressure, which is essential for reliable chromatographic analysis.
