Non-destructive measurement of the porosity, pore volume, the radii and pore size distribution, the evaluation of the contact angle of wetting and hydrophilic-hydrophobic properties of multicomponent materials.

Porotech 3.1

Automated Standard Porosimeter Porotech 3.1, based on the method standard capillary porosimetry. After preparing a package of samples and standards unit takes measurements automatically.

A new method of Standard Porosimetry (MSP) for investigation of any type of porous materials, including soft, frail, amalgamated materials, films and powders has been developed. The method is relatively simple and non-destructive and can be used for measurements in a wide range of pore sizes from 0.3 nm to 3×106 nm. The method is currently being used to study porous materials such as carbon nanotubes, membranes, thin films, ceramics, electrodes for batteries, paper etc., and can be used in other applications, including nanotechnology. The MSP employs numerous manual operations.

Standard Porosimeter Porotech 3.1 – Capabilities

• Characteristics of porous size distribution depending on values of contraction pressure and temperature.

• Integral and differential distribution of pore volume as a functions of the pore radius within range from ~0.3 nm to 3x105 nm.
