Biotechnology and Healthcare

One industry sector that increasingly demands precise information on pore size and related characteristics is biotechnology and healthcare. Considering the number of porous materials now used in this branch of science, in such a variety of advanced applications, it is not surprising that there is much interest in the instruments described on this website.

Automated Filter Cartridge Tester

Automated Filter Cartridge Tester - PMI

Filter cartridges are used in many industries, and in all cases there is a need to be aware of – and measure – their porous characteristics, properties and capabilities for R&D and quality control reasons. Pore size and material characterisation specialist PMI has an Automated Filter Cartridge Tester which assesses these products quickly, accurately and non-destructively. Continue reading Automated Filter Cartridge Tester

Batteries and Battery Separators

Batteries and separators

The porous nature of various elements in the structure of a battery has a crucial effect on its performance and is the subject of much material characterisation work using PMI instruments. Materials used to separate the cells in a battery are of particular concern, but so too are a number of other key components. Continue reading Batteries and Battery Separators

Sample testing

Before you set out to buy an instrument for characterisation of any material, the first question you should ask is what will be the most appropriate method to obtain the information needed. As well as developing and manufacturing a range of high-quality analytical equipment, including porometers, permeameters and porosimeters, PMI can advise on what techniques to use – and can even do the analysis for you.

Pore Size in Automotive Components

automotive

The automotive industry is just one of the many sectors that regularly make use of instruments for the measurement of pore size and other pore characteristics. Perhaps the most obvious components for which information on pore structure is needed – but not the only ones – are the various filters that play vital roles in the functioning of a vehicle.

What Is a Porosimeter?

Liquid extrusion porosimeter

While exploring the topic of pore size and other characteristics of porous materials, the instruments we come across most regularly are the many and varied porometers and permeameters. Occasionally on this pore size website we have touched upon porosimeters, and for clarity I would like to return briefly to that subject today. Continue reading What Is a Porosimeter?

What Does a Permeameter Do?

PMI liquid permeameter

When characterising the porous nature of a material we measure many aspects of pore size, but often we are also interested in the material’s permeability. This is, quite simply, a measurement of its ability to allow fluid to flow through it. We can determine permeability using a permeameter, of which many different varieties exist, and this is the topic I would like to dwell upon today. Continue reading What Does a Permeameter Do?

Cartridge Bubble Point Tester

Straying just a little from the subject of pore size, but onto a topic that is relevant to many users of porometers and other pore characterisation instruments, my attention has been caught by a new product from PMI. It’s a cartridge bubble point tester… Continue reading Cartridge Bubble Point Tester

Compression Liquid Extrusion Porosimeter

PMI Compression Liquid Extrusion Porosimeter

A very versatile instrument that I’ve been looking at recently is the Compression Liquid Extrusion Porosimeter from PMI. This clever piece of equipment will measure pore volume like a mercury intrusion porosimeter, although without the use of mercury or any other toxic substance, and will also measure liquid permeability like a permeameter. What’s more, it can do so while holding the sample under compressive stress. Continue reading Compression Liquid Extrusion Porosimeter

Cake Forming Porometer

Cake

If I say that today I’m going to talk about cake, you might think I’m deviating from the normal subject matter of the Pore Size website. However, cake actually has a vital role to play in the world of filtration, which in turn involves porometry. Not the kind of highly calorific cake that’s so often my downfall but the cake that forms on a filter’s surfaces. Continue reading Cake Forming Porometer
