These black polypropylene (PP) screw caps are designed with chemically inert PTFE /silicone plain septa for secure, leak-proof sealing of 4 mL screw vials. The plain septa (non-slit) provide excellent chemical resistance and minimize contamination, ideal for HPLC, GC, LC-MS, and general laboratory applications. Compatible with standard 13 mm screw-thread vials, these caps ensure reliable sample integrity during storage and analysis. Each pack contains 100 closures, perfect for consistent, high-throughput laboratory workflows.
