POREX® multi-function sampling devices reduce sample error, instrument downtime and streamline workflow
The accuracy of test results is dependent upon the integrity of the sample. Sample preparation errors are minimized with POREX multi-functional sampling devices that limit analyte loss, reduce methodology interference and allow for extended storage during sample preparation steps.
Our portfolio of single-use preparation devices can help simplify almost any sample preparation process.
The POREX FILTER SAMPLER® Blood Serum Filters effectively separate fibrin and gel particulates that can potentially interfere with diagnostic equipment systems and allow for extended in-tube storage. Our POREX SQ-EASY® PreFilter provides an all-in-one system for filtering viscous samples prior to diagnostic testing.

Pre-Analytic Serum Filters

Effectively filter blood serum samples of problematic gel and fibrin
POREX® FILTER SAMPLER® Blood Serum Filters are the industry leading sample filtering system used for the separation of serum or plasma from centrifuged blood specimens contained in the standard 16, 13 or 10.25mm evacuated blood collection tubes.
Specifically designed to function as a three-in-one filtration system that filters, pipettes and stores samples, the Filter Sampler system allows for up to seven days in primary tube storage and reduce the need for re-collects. These clinical laboratory devices:
- Protect sample integrity and instrument performance – FILTER SAMPLER technology eliminates gel particulate and fibrin in the sample, which can interfere with assay and methodology results.
- Improve efficiency – Reduce instrument downtime and allow direct sample access rather than secondary container pour-off.
- Extend storage life – CERTIFIED PURE POREX® FILTER SAMPLER is independently tested to allow for up to even-day serum storage in the primary blood collection tube.
