Colloid Metrix - Particle Size - NANO-flex® II

The NANO-flex® II 180° DLS system measures particle size distributions of suspensions and emulsions in the range of 0.3 nm to 10 μm and concentrations up to 40 % by volume. The principle of heterodyne 180° backscattering applied here is characterized by its high selectivity in the nm range and a very high resolution; it is also suitable for samples with a wide or multi-modal size distribution. Due to the low penetration depth of the laser light, samples of high concentration are measured without disturbing multiple scattering. Compared to cuvette based systems, many samples can be measured without dilution in original concentration. The dip-in probe used in the NANO-flex® II has a diameter of 5.5 mm and allows a wide range of applications. In conjunction with the IPAS extension, particle size distributions can be measured inline. In combination with the Stabino® II, stability ranges and critical coagulation points can be determined.

NANO-flex® - Size sensor everywhere

Colloid MetrixWith a focus on the two areas of application, technically in the Colloid Metrix and clinically in the Particle Metrix, the founders, Margret Böck and Dr. Hanno Wachernig, set a clear signal both inwards and outwards. Here innovations have matured, which offer a high customer benefit in the respective area and therefore deserve increased attention.
