2 Micron SS Frit, 30# Inline Pre Column Filter Protection For HPLC or UHPLC Columns

– Placed directly before the column – Removes particles from the sample and injection system – Minimizes band spreading due to off-column effects caused by 10 mm, 20mm, and 30mm diameter sieves and tapered inserts – Can be used with any semi-preparative column

The function and principle of the inline filter are to filter microparticles from the mobile phase and prevent the analytical column from being clogged.

  • Inlet/Outlet: Female/Male 10-32
  • Frit:0.5 and 2 micron porosity
  • Pressure Rating:15,000 PSI

Features and Applications:

Placed between the pump and sample injection valve protects valve seal wear and column from particles released through normal piston seal wear.


The inline filter is used to filter impurities and solid particles from the mobile phase and to protect the liquid phase system. It is usually installed at the back end of the pump, in front of the autosampler. It is a ferrule type, but its just with a HPLC Frit, independent of the type of lc column. In practice, due to the installation position of the inline filter and the fact that the filter cartridge is only a frit, it can only be used to filter impurities from the mobile phase.


– Specially engineered for inline filtration
– Versions include Micro, Standard, and Semi-Preparative
–  Bio-inert and stainless steel options offered
– Variety of porosities, application appropriate
