Description
The Caps for RIA Vial HDPE are precision-molded closures designed to provide airtight and leak-proof sealing for RIA (Radioimmunoassay) vials. Made from medical-grade high-density polyethylene (HDPE), these caps offer excellent chemical resistance, durability, and compatibility with a wide range of laboratory reagents and biological samples.
These caps ensure secure sample containment during centrifugation, handling, or storage — ideal for clinical diagnostics, RIA procedures, and laboratory research applications.
