The Shimadzu Needle Seal (228-41540-01) is a precision-manufactured PEEK injection port seal used in Shimadzu HPLC autosampler systems. Positioned at the autosampler needle seat, it guides the injection needle while creating a high-pressure, leak-free seal during sample aspiration and injection. Manufactured from chemically inert PEEK (Polyether Ether Ketone), the seal offers excellent resistance to aggressive HPLC solvents, buffers, and high-pressure operation. Routine replacement of the needle seal helps prevent sample carryover, solvent leakage, injection volume inaccuracies, and pressure loss, ensuring consistent analytical performance and prolonging autosampler life.
