The instrument is used for simultaneous dynamic and static light scattering with transparent and turbid samples and is equipped with a HeNe laser light source with a wavelength of 632.8nm and a maximum power of 35 mW. The sample is filled into cylindrical glass cells of a diameter of 3, 5 or 10 mm or 10 mm square cells and placed in the temperature controlled index-matching bath. The scattered light is detected within an angular range of 15 to 140° by two efficient Avalanche Photo Diodes and processed by a Flex correlator in a 3D cross-correlation configuration. In aqueous samples we have access to scattering vectors between 0.0034 and 0.025nm^-1.The apparatus is equipped with a sample goniometer to characterize non-ergodic samples. It uses the new modulated cross correlation technique for optimized signal content.

The instrument is typically used for:

-   Molecular weight determination (Zimm plots).

-   Particle sizing via hydrodynamic radius.

-   Particle form factor determination.

-           Structure factor and dynamic structure factor measurements for strongly interacting dilute and concentrated systems.
