Catalog Number - 49681-05-005

The 49681-05-005 ARE‑Applied Research Inline Filter is an all‑PEEK inline filtration solution supplied in a multi‑unit pack, designed for HPLC systems operating under standard pressure conditions.

Using replaceable PEEK‑encased stainless steel (0.5 µm) filter elements, this system helps reduce particulate contamination, minimize system noise, and prevent column clogging, improving analytical consistency and column lifespan. The filter also functions as an inline union with filtration, adding flexibility to system setup.

Each unit features a reusable holder and is designed for quick installation and easy filter replacement, making it well suited for routine laboratory use.
