Micromeritics Autopore 9600 mercury porosimeter

The Micromeritics Autopore 9600 mercury porosimeter comes in two models: the 9605 with four low-pressure ports and two high-pressure ports @ 33,000 psia; and the 9620 with four low-pressure ports and four high-pressure ports @ 60,000 psia. It has the ability to measure pore diameters from 0.003 to 500 µm.

It features high-resolution (sub-microlitre) measurement of intrusion/extrusion volumes. The precision of the product is said to allow for the development of tighter sample specifications, improved production processes and high-quality research data. The device operates in scanning and time- or rate-of-intrusion equilibrated modes and collects high-resolution data; better than 0.1 µL for mercury intrusion and extrusion volume.

The mercury porosimetry analysis technique is based on the intrusion of mercury into a porous structure under stringently controlled pressures. Besides offering speed, accuracy and a wide measurement range, mercury porosimetry permits the user to calculate numerous sample properties such as pore size distributions, total pore volume, total pore surface area, median pore diameter and sample densities (bulk and skeletal).

The AutoPore V Series mercury porosimeters can determine a broader pore size distribution quickly and accurately. The instrument features enhanced safety features and offers data reduction and reporting choices that provide information about pore geometry and the fluid transport characteristics of the user’s material.
