Liquid Extrusion Porosimeter: Safe and Accurate Pore Structure Analysis Without Mercury
June 11, 2026

INTRODUCTION
Understanding pore structure is vital across filtration, pharmaceuticals, ceramics, and biotechnology sectors. The Liquid Extrusion Porosimeter provides an environmentally responsible alternative to mercury-based systems, using safe liquids to determine through-pore volume, pore size distribution, and material permeability without health or environmental risks.
WHAT IS A LIQUID EXTRUSION POROSIMETER?
This instrument measures pore dimensions in porous materials by monitoring liquid extraction under applied pressure. It evaluates: through-pore volume, pore size distribution, liquid flow capacity, functional pore structure, material transport properties.
HOW DOES LIQUID EXTRUSION POROSIMETRY WORK?
Testing Procedure: 1) Sample is saturated with liquid; 2) Sample placed in test chamber; 3) Gradual pressure application in increments; 4) Liquid extraction from pores as pressure increases; 5) System quantifies extracted liquid volume; 6) Software analysis determines pore dimensions and permeability. This non-destructive approach preserves sample integrity while generating reliable data.
