Long-life syringes were developed for extreme conditions that include harsh chemicals as well as abrasive particulate matter. The plunger tip is made from UHMWPE (Ultra High Molecular Weight Poly Ethylene) which is harder than PTFE to better resist scratching. In addition, the plunger rod is made from 316 stainless steel which offers exceptions chemical resistance. The standard syringes listed below are designed to fit Hamilton 30 mm and 60 mm syringe pumps. In addition to this a variety of syringe terminations and plunger styles are readily available upon request to meet any need.
