    Pore Size Analyzer

    Overview Knowledge Standards Terms
    The pore size analyzer measures the size distribution and volume of internal pores in materials through gas adsorption or mercury intrusion porosimetry. It is used to evaluate the structural characteristics of porous media such as filter materials and catalysts, and finds applications in the chemical and materials fields.
    Selection
    When selecting a pore size analyzer, consider the material type and pore size range. Gas adsorption is suitable for microporous materials, while mercury intrusion porosimetry is appropriate for macroporous materials. Pay attention to instrument accuracy, sample processing capacity, and ease of operation, and determine the choice based on specific testing requirements.

    Types and Selection of Paint Viscosity Cups
    As a simple tool for measuring the liquid outflow time, the viscosity cup is mainly categorized into various types such as the Tu-4 cup, ISO cup, Ford cup, and Zahn cup, based on standards from different countries and regions. These cups differ in orifice size, capacity, and the types of fluids they are suitable for.
