The CPS DC24000 UHR is an ultra high resolution particle size analyser with unparalleled resolution accuracy, even when measuring nanoparticles less than 100nm. With clean separation of narrow peaks that differ in size by as little as 2%, the CPS DC24000 UHR uses Differential Centrifugal Sedimentation (DCS) to accurately size, detect and measure small changes in particle size.
It is also used to measure nanoparticle coating thickness, ideal for a range of applications including work with gold and silver nanoparticles.
Dynamic Balancing Module – displays disc speed, internal temperature and warns if the system is unbalanced, ensuring instrument longevity
High sensitivity – min. detection limit below 10-8 active sample for narrow peaks, allows small sample size
Highly reproducible results
Dynamic range capability – >1000 for measurement of broad and multimodal distributions
Measurement of particles of virtually any density
Extensive data reporting options – including multiple distribution overlays

CPS Disc Centrifuge UHR: A high resolution particle size analyser
The CPS DC24000 UHR is an effective particle size analyser for ultra high resolution, high accuracy particle sizing. 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 particles and then measures them as they pass a light source detector – providing full characterisation in real time.
Ultra high resolution particle sizing 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
“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.”
“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)”
“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.”
“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. ”
“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. ”
