Column Filters, for HPLC, 2.0 um Stainless Steel filter element and All-PEEK body. Disposable, with end plugs. Natural. Cogent Brand. 10/PK.
Additional Info:
The Cogent In‑Line Column Filter (2.0 µm) in the 10‑pack configuration is a cost‑effective solution for laboratories that require routine pre‑column protection with minimal pressure impact. These disposable in‑line filters are designed to protect analytical HPLC columns from undissolved particulates and pump‑seal shedding, helping preserve column performance and extend column life.
Each unit features a 2.0 µm stainless steel filter element housed in a natural‑color all‑PEEK body, providing excellent chemical compatibility and a metal‑free flow path outside the filter element. The larger pack size reduces reordering frequency and lowers per‑unit cost, making it ideal for high‑throughput or production environments.
The universal connection design fits all standard analytical HPLC column threads and pilot lengths. Installation is straightforward using hand tightening or a wrench, enabling fast replacement during routine maintenance.

Usage & Replacement Guidance
Monitor system backpressure when in‑line filters are installed. A gradual pressure increase typically indicates filter loading.
Replacement steps:
Reduce system pressure to atmospheric
Disconnect the used filter
Dispose of the unit
Install a new filter and resume operation
These devices are commonly referred to as pre‑column filters due to their upstream placement.
Pressure Rating & Compatibility
Maximum pressure: 4,500 psi
Compatible with: Analytical HPLC systems
