Catalog Number - 9504S-10C-BK

The 9504S‑10C‑BK MICROSOLV™ Screw Caps are selected for chromatography workflows requiring reliable autosampler sealing and bonded septa stability for 4 mL vial applications. The bonded silicone rubber/PTFE septa design helps minimize septa movement and supports consistent injection performance during routine analytical use.

Manufactured with black knurled polypropylene caps and bonded silicone rubber/PTFE septa, these caps are designed for use with standard 13‑425 thread, 15 × 45 mm autosampler vials commonly used in older Waters® and Shimadzu autosampler systems.
