Plug. PEEK, 1/4-28, ARE-Applied Research brand. 10/PK.
Additional Info:
49025-01N-010 ARE‑Applied Research PEEK Plugs are precision‑engineered sealing components designed for HPLC mobile phase delivery caps and solvent bottle systems, ensuring unused ports remain tightly sealed and contamination‑free.
Manufactured from high‑performance PEEK (polyether ether ketone), these plugs offer excellent chemical resistance and mechanical durability, making them ideal for demanding chromatography and analytical laboratory environments.
The standard 1/4‑28 threaded design ensures compatibility with common solvent delivery caps and fluid handling systems used in HPLC, UHPLC, and LC‑MS workflows.
Also commonly used with Mobile Phase Delivery Cap 58820‑06, these plugs help prevent air and oxygen ingress when ports are not in use, supporting stable and reproducible mobile phase conditions.
