Column Filters, for HPLC, 2.0 um Stainless Steel filter element and All-PEEK body. Disposable, with end plugs. Natural. Cogent Brand. 5/PK.
Additional Info:
The Cogent In‑Line Column Filter (2.0 µm) is a disposable pre‑column protection device designed to protect analytical HPLC columns from larger particulate contamination while maintaining lower pressure impact compared to finer‑pore filters. This configuration is commonly selected when sample matrices are cleaner or when methods are sensitive to additional restriction.
Each filter incorporates 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 itself. These filters effectively trap undissolved particles and pump‑seal debris, helping prevent irreversible column damage and premature performance loss.
The universal connection design fits all standard analytical HPLC column threads and pilot lengths. Installation is straightforward using hand tightening or a wrench, allowing fast replacement during routine maintenance or method setup.

Usage & Replacement Guidance
When an in‑line column filter is installed, system backpressure should be monitored. A gradual increase in pressure typically indicates filter loading.
To replace:
Reduce system pressure to atmospheric
Disconnect the used filter
Dispose of the unit
Install a new in‑line filter and resume operation
These devices are commonly referred to as pre‑column filters because they are installed upstream of the analytical column.
Pressure Rating & Compatibility
Maximum pressure: 4,500 psi
Compatible with: Analytical HPLC systems
Not recommended for: UHPLC pressure ranges
For higher particulate retention, a 0.5 µm version is available within the same filter family.
