Description
Particulate matter can originate from several places in a standard chromatography (or related) system. Whether stemming from typical wear of the piston seals or from particulate shedding of the rotor seal over time – or even from the sample being analyzed – these extra, non-desired particles can cause problems with most systems. When these particles lodge inside sensitive equipment or collect on the surface of a column frit, they often lead to erratic flow rates or increased system pressures and frequently result in the need to replace an expensive column or perform maintenance on system hardware.
To prevent these problems from occurring, Upchurch Scientific has manufactured a number of high pressure inline filters. By placing these filters inline, the internal frits capture most of the particulate matter suspended in the mobile phase and protect major system components.
There are different styles of inline filters available for different regions in the flow path or for different flow rate levels; these styles are described below.
NOTE: For those inline filters mentioned below that utilize separate frit discs with a diameter of .250”, it is possible to customize those filters with different frits by simply choosing another version with the same diameter. To see other frits that may be used in the inline filter assembly of your choice, click here. Once there, look for a frit assembly diameter of .250” or .254”; these may be used as replacements for the frit prepackaged in many of the inline filter assemblies listed below.
NOTE: All of our high pressure inline filters designed for use with 1/16” OD tubing feature 10-32 coned internal ports that will accept our traditional Fingertight fittings.

In addition to the Fingertight fittings, the stainless steel inline filters will accept stainless steel 10-32 threaded fittings; to view the various stainless steel fitting options available, please click here.
