Advanced Materials Engineered for Diagnostics Performance
Reliable diagnostic performance starts with high-quality, functionally validated materials. Porex engineers have extensive experience developing and optimizing filtration, wicking, and absorption components for diagnostic workflows, resulting in a deep understanding of how material properties impact sample collection, analyte recovery, and assay sensitivity. Diagnostic developers rely on this expertise to address a wide range of material and workflow challenges, from sample collection through final nucleic acid purification.
Demonstrated outcomes include:
- Removed inhibitors from sputum samples, improving qPCR detection by 2 Cts
- Streamlined fecal sample clarification, reducing a 4+ hour workflow to 5 minutes
- Developed centrifuge-free filters that isolate plasma and pathogens from whole blood

Core Solutions and Technologies
Porex’s diagnostics expertise is organized around three critical stages of the sample-to-answer workflow.
Sample Collection Media
Porex engineers absorbent pads, collection swabs, and microsampling materials that control sample uptake, retention, and release, reducing variability from user technique and supporting consistent analyte recovery across collection formats.
Sample Preparation Media
Porex depth filtration media and track-etched membranes are engineered to remove particulates, separate blood components, and eliminate inhibitors from complex biological matrices, enabling reliable and reproducible downstream analysis.
Nucleic Acid Isolation
Porex silica-embedded frits integrate functionalized silica within a three-dimensional polymer scaffold, enabling high-efficiency DNA and RNA extraction directly from complex clinical matrices including sputum, whole blood, and stool.
