Class Leading, Proven Performance Establishing a New Benchmark for Operational Safety

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 you 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 more quickly and accurately than other methods. This instrument also features enhanced safety features and offers new data reduction and reporting choices that provide more information about pore geometry and the fluid transport characteristics of your material.

Optional Advantages:

  • Ability to measure pore diameters from 0.003 to 1100 µm*
  • Controlled pressure can increase in increments as fine as 0.05 psi from 0.2 to 50 psia. This allows detailed data to be collected in the macropore region
  • High-resolution (sub-microliter) measurement of intrusion/extrusion volumes produces extraordinary precision allowing the Development of tighter sample specifications, improved production processes, and high-quality research data
  • Operates in scanning and time- or rate-of-intrusion equilibrated modes
  • Real-time diagnostics provide knowledge of an issue before it becomes critical or impairs your analytical results
  • Collects extremely high-resolution data; better than 0.1 µL for mercury intrusion and extrusion volume
  • Improved linear motion for high-pressure chamber closure

Design Advantages:

  • Improved safety features reduce the risk of mercury spills and operator exposure
  • Available with four low- and two high-pressure ports for increased sample throughput
  • Available in 33,000 psia or 60,000 psia models
  • Low-noise, high-pressure generating system
  • A quick-scan mode allows a continuous pressure increase approximating equilibrium and providing faster screening
  • A choice of correction routine for baseline (automatic, differential, or manual) produces greater accuracy by correcting for compressibility and thermal effects caused by high pressure
  • Choice of pressure ramping methods lets you choose the scanning mode for high-speed or on-demand results, or equilibration mode for more accurate results with greater detail
  • Mercury temperature sensor allows automatic calculation of mercury density used for penetrometer calibrations
  • MicroActive software allows you to interactively manipulate data, define custom reports, and quickly achieve analytical results
  • Compensation for material compression under high-pressure analysis

Four Models:

The AutoPore V is available in four models to best match the needs of individual
quality assurance and research labs.

High Pressure 2 Ports @ 33,000psia 2 Ports @ 60,000psia



Low Pressure 2 Ports 2 Ports
High Pressure 1 Port @ 33,000psia 1 Port @ 60,000psia

Penetrometer Rack:

Safely store and transport penetrometers to prevent breakage and unnecessary replacement.

Mercury QuikVac:

Mercury QuikVac is an excellent low-cost method for quickly containing mercury spills. The device is designed to be specifically useful in collecting those elusive mercury droplets and small mercury-contaminated particulate matter.
Mercury is collected in a 250-mL recovery vessel and a replaceable 0.3 – 0.5 micron activated carbon filter assures that the device exhausts clean, safe air.

Pharmaceuticals: Porosity and surface area play major roles in the purification, processing, blending, tableting, and packaging of pharmaceutical products as well as a drug’s useful shelf life, its dissolution rate, and bio-availability.

Ceramics: Pore area and porosity affect the curing and bonding of greenware and influence strength, texture, appearance, and density of finished goods.

Adsorbents: Knowledge of pore area, total pore volume, and pore size distribution is important for quality control of industrial adsorbents and in the development of separation processes. Porosity and surface area characteristics determine the selectivity of an adsorbent.

Catalyst: The active surface area and pore structure of catalysts influence production rates. Limiting the pore size allows only molecules of desired sizes to enter and exit, creating a selective catalyst that will produce primarily the desired product.

Aerospace: Surface area and porosity of heat shields and insulating materials affect weight and function.

Fuel Cells: Fuel cell electrodes require controlled porosity with high surface area to produce adequate power density.

Geoscience: Porosity is important in groundwater hydrology and petroleum exploration because it relates to the quantity of fluid that a structure can contain as well as how much effort will be required to extract it.

Filtration: Pore size, pore volume, pore shape, and pore tortuosity are of interest to filter manufacturers. Often, pore shape has a more direct effect upon filtration than pore size because it strongly correlates with filtration performance and fouling.

Construction Materials: Diffusion, permeability, and capillary flow play important roles in the degradation processes in concrete, cement, and other construction materials.

Paper: The porosity of print media coating is important in offset printing where it affects blistering, ink receptivity, and ink holdout.

Medical Implants: Surface area and porosity of heat shields and insulating materials affect weight and function.
