The Beckman Coulter DelsaMax series of Nanoparticle analysers, brought to you by Meritics, are some of the fastest and easiest to use nanoparticle analysers available.
They are optimised for biological materials and similar precious and vulnerable particles. This makes the DelsaMax family ideal for zeta potential measurements and size characterisation of proteins, carbon nanotube suspensions and emulsions.
There are three members of the DelsaMax family, the DelsaMax PRO, the DelsaMax CORE and the DelsaMax ASSIST, each instrument configured for different tasks depending on your requirements.
The DelsaMax PRO allows simultaneous analysis of both particle size and zeta potential for sample volumes as small as 45 ?l.
It is the DelsaMax’s speed of analysis that leaves delicate samples unperturbed and this is thanks to the 31 different detectors used during the zeta potential measurement and the separate detector that is used for particle sizing.
The combination of independent measurement systems allows for parallel assessment of both sample particle size and zeta potential.
This processing compares with other instruments that require closer to a minute’s measuring time - time that is going to do nothing for the integrity of your precious sample.
The DelsaMax PRO system also allows for valuable instant result cross-checking and means that the DelsaMax PRO is able to measure the zeta potential of samples as low in concentration as the equivalent of 1mg/ml of lysozyme.
Plus, there are no tricky cuvettes to be manipulated, the sample is simply added by syringe, and there is an elegant touch screen for following the whole process.
The DelsaMax CORE is designed for nanosizing of particles down to 1?L sample volumes.
The CORE minimum sample volume is the smallest currently on the market. The DelsaMax ASSIST is for sample preparation.
It pressurises the sample cell to reduce interference and bubbling and hence optimises particle preparation - improving the reproducibility and reliability of the measurements of samples that are prone to gassing when an electric field is applied.
