Hamilton provides a variety of custom needle syringes that are designed for use with manual HPLC injection ports. Our syringes are handmade with an unmatched attention to detail. The manufacturing process and quality assurance procedures ensure that every syringe we sell will provide superior accuracy and precision as well as cycle life. The electropolished needle slides smoothly into the injection port reducing the wear on valuable seals. Choose the sub category that is associated with your injection valve to find the syringes available for your HPLC.
