THOMSON Syringe Filters


Syringe Filters

Thomson offers a comprehensive range of non-sterile disposable syringe filters for reliable sample preparation. Automated manufacturing processes insure membrane quality so particulates are removed from every sample, extending analytical column lifetime and minimizing injection valve damage.

Thomson Syringe Filters have standard Luer-lok/Luer connections and are either 0.22 or 0.45μm porosities in 4, 13, 25 and 30mm diameters. They are available in a wide selection of membranes, including Nylon, PTFE and PVDF, supporting all common sample preparation applications.

A retaining ring seals the polypropylene housing, preventing leaks and sample loss. All Filters are color coded, for easy identification to insure the correct filter is selected for each sample.


Thomson Syringe Filters are supplied in re-sealable containers allowing easy storage and preventing contamination during multiple opening/closing. For particulate laden samples, filters are also available with an integral depth filter.

From the list below, select the best filter for your sample to list its available options.
