CPS Disc Centrifuge UHR    

The CPS DC24000 UHR is an effective analytical tool for ultra high resolution, high accuracy measurement of particle size distribution. Highly poly-dispersed particles can be measured in the size range of ~3.0nm to ~60 microns, at 2 to 10 times better resolution than any other particle sizing instrument, regardless of measurement technique.

Utilising Differential Centrifugal Sedimentation (DCS), the CPS Disc Centrifuge UHR offers the unique ability to resolve very close multimodal particle distributions and to distinguish extremely small shifts in particle size. Rather than using a predictive algorithm, the instrument physically separates the nanoparticles and then measures them as they pass a light source detector - providing full characterisation in real time.

Do you know the real size of your nanoparticles? Watch an introduction to the CPS Disc Centrifuge UHR below.


Key Features:


  • Ultra high resolution with clean separation of narrow peaks that differ in size by as little as 2%
  • Able to detect and measure very small and subtle changes / differences in particle size
  • Able to measure / monitor nanoparticle coating thickness
  • In-built PC: the display shows the actual disc speed, internal temperature and it will show a user if the system is unbalanced
  • Dynamic Balancing Module ensures instrument longevity
  • Very high sensitivity; minimum detection limit below 10-8 gram active sample for narrow peaks
  • Highly reproducible results
  • Dynamic range capability >1000 for measurement of broad and multimodal distributions
  • Measurement of particles of virtually any density
  • Wide range of data presentation options, including multiple distribution overlays

Product Recommendations:

“We purchased the CPS Disc Centrifuge from Analytik in 2008 expanding our range of particle and material characterisation instrumentation. The ability of the instrument to detect and measure small changes in particle size distribution enables us to determine coating thickness on particles and multi-mode particle distributions. It’s easy to use so we now have many trained users. We get great support from Analytik for servicing, extra training and answering any queries we might have about samples.”

Alison Crossley, Manager, Oxford Materials Characterisation Service

We have been using the CPS Disc Centrifuge routinely for several years to analyze aqueous dispersions of gold nanoparticles in the 3 to 25 nm size range. It copes very well with the presence of multimodal size distributions, which usually lead to the appearance of well separated peaks. For monodisperse samples the method uniquely provides the opportunity to monitor changes in the thickness of the organic ligand shell down to the length of a single chemical bond (see Krpetic et al. ACS Nano 2013)”

Mathias Brust, Professor of Chemistry, University of Liverpool

We are using the CPS Disc Centrifuge on daily bases to analyze the aqueous colloidal dispersions of biocides in less than 100 to 500 nm size range. The instrument operation is very easy and results are reproducible with comprehensive.”

Farnoosh Kianfar, Senior Formulation Scientist, Lonza

Here at Intertek Wilton, we have been using the CPS Disc Centrifuge to provide a particle sizing service to a wide range of industries including Pharmaceutical and Materials based businesses. This instrument should be an essential part of any laboratory where particle sizing is performed as it enables accurate measurement of particles where other techniques (e.g., laser diffraction and PCS) run into difficulties due to size and concentration, I'd also recommend Analytik because of their unceasing support whenever we require advice on running materials we have never encountered before. ”

Jonathan Whitehead, Senior Experimental Scientist, Intertek Testing Services

Before we purchased our CPS we routinely analysed samples by DLS. While sample analysis is not as straight forward as with our DLS instrument (it requires you to build a sucrose gradient inside the disc prior to analysis, where with our DLS instrument you just insert the cuvette and press go) the resolution far surpasses what we were used to, and is well worth the little extra effort. We routinely analyse samples looking to detect the level at which influenza virus particles may be present. ”
