Benefits of the Multisizer 4e Coulter Counter

In my July post I summarised the features and capabilities of the new Multisizer 4e Coulter Counter from Beckman Coulter. There is never enough space in a short post to do justice to such a product advance, so I thought I would return to it and say something about what it will mean to those for whom particle characterisation is a vital task.

Multisizer 4e


A new member has been added to the Coulter Counter family, from Beckman Coulter, in the shape of the Multisizer 4e. With this instrument, particles and cells as small as 0.2 microns can be accurately counted and measured. Continue reading Multisizer 4e

Particle Size and Concentration in Oils


If you go to the Beckman Coulter website,, look for the type of product in which you are interested – say Coulter Counter – and then click on ‘Literature’ in the right-hand column, you will open up a whole world of information. For example, I’ve just come across some application notes for use of a Beckman Coulter Multisizer 3 Coulter Counter in determining the size and concentration of particles in oils.

For the most complex of sizing and counting applications, Meritics recommends the Multisizer™ Series of Coulter Counters® from Beckman Coulter®. If, however, your aim is to obtain relatively simple – but quick and accurate – counts of cells or other particles, you need look no further than Beckman Coulter’s Z™ Series.

The Multisizer 4 Coulter Counter

coulter counter instrumentTo demonstrate the advanced technology and versatility of coulter counters, let’s have a close look at the Multisizer™ 4 Coulter Counter® from Beckman Coulter®. Meritics considers this to be, quite simply, the most versatile and accurate particle sizing and counting analyser on the market.

In common with other coulter counters, it uses the Coulter Principle to give precise, high-resolution information on size distributions in terms of number, volume and surface area – all in one measurement.

It will analyse particles ranging in size from 0.4 µm to 1600 µm and, importantly, its response is not affected by the colour, shape, composition or refractive index of those particles. Continue reading The Multisizer 4 Coulter Counter
