Column Filters, for HPLC, 0.5 um Stainless Steel filter element and All-PEEK body. Disposable, with end plugs. Black. Cogent Brand. 10/PK.
Additional Info:
The Cogent In‑Line Column Filter (0.5 µm) in the 10‑pack configuration is the most popular column‑protection solution for laboratories running routine analytical HPLC workflows at scale. This disposable pre‑column filter protects analytical columns from undissolved particulates, sample debris, and pump‑seal shedding, all of which can shorten column life and compromise performance.
Each unit contains a 0.5 µm stainless steel filter element housed in an all‑PEEK body, providing excellent chemical compatibility while maintaining a metal‑free flow path outside the filter element. The larger pack size is ideal for high‑throughput environments, reducing per‑unit cost and minimizing downtime associated with reordering.
A universal column connection fits all standard analytical HPLC column threads and pilot lengths. Installation is quick and repeatable using hand tightening followed by a quarter‑turn wrench, making replacement straightforward during routine maintenance.

Usage & Replacement Guidance
When in‑line column filters are installed, system backpressure should be monitored. A gradual increase in pressure typically indicates filter loading.
To replace:
Reduce system pressure to atmospheric
Disconnect the in‑line filter
Dispose of the used filter
Install a new unit and resume operation
These devices are also commonly referred to as pre‑column filters due to their installation position upstream of the analytical column.
