What is the best way to get support for your Malvern Panalytical instrument? Well, we have several methods, and I am going to let you in on a secret. The easiest is through our new web portal. Just fill in…READ MORE >

Rush orders – there are times when we need something quickly, with fast delivery. And this can also happen with rush orders for laboratory equipment, like a Zetasizer, an OMNISEC, or any of our systems. If you are in a…READ MORE >

The Zetasizer uses electrophoretic light scattering to find the charge of particles. This charge can mean the difference between dispersed particles and flocculated sediment. That is why Zeta potential in water treatment is important to get cleaner H2O: we want…READ MORE >

The popular Zetasizer can measure zeta potential in a disposable and reusable cuvette, DTS1070. This capillary cell is more affordable than the traditional dip cell, ZEN1002. But which one is better? So how do you know if your zeta cell…READ MORE >

This year’s Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy (or Pittcon for short) is taking place Online, from March 8 – March 12, 2021. As in previous years, there is a large selection of Pittcon short courses 2021 relevant…READ MORE >

We launched the latest generation of the Zetasizer family, the Advance series. As a result, I received variations of two questions a few times: What is so good about the new version? Can you give me some bullet points? Well,…READ MORE >

How can we get the fire cloud particle size? Typically I write about nanoparticles. The current fire situation in California reminded me that the larger than nano-size range is also affecting our daily life. While smoke forms clouds we can…READ MORE >

This question landed on my desk recently. “We have a Zetasizer in our lab. We have taken the size and zeta potential of a mixture of two particle types. I am wondering to what extent the zeta potential and size would…READ MORE >

The Zetasizer Nano in review… When we introduced the Zetasizer Nano at www.zetasizer.com in 2003 it was ground-breaking. There were several reasons for it. For instance, a step-change development that created an entirely new generation of lab equipment. At the…READ MORE >
