This is a fingertight bioanalytical inline filter, comprising a PEEK holder and a 5 μm titanium PEEK-encased frit.

• Protects the injector from particulates
• Compatible with all HPLC systems
• Replacement 5 μm and 2 μm titanium PEEK-encased frits are available

Placed between the pump and sample injection valve, the in-line filter traps particles released through normal piston seal wear within the pump. It is recommended that the frits are checked frequently and replaced as soon as they contribute to a system back pressure.
