Versatile Light Scattering System for Research Applications

Automatic, modular system for SLS and DLS

The BI-200SM goniometer from Testa Analytical Solutions eK has been designed to make it the finest instrument available for research applications of light scattering.

Ideal for macro-molecular studies and submicron particle sizing

Offering unmatched performance for both Static Light Scattering (SLS) and Dynamic Light Scattering (DLS) experiments the BI-200SM research goniometer is a precision instrument for undertaking exacting measurements

Modularity simplifies system expansion

Favoured by leading research groups around the world, the BI-200SM’s modularity makes system expansion simple. Featuring a standard optical rail, the BI-200SM can be used with neutral density filters, polarisers, auxiliary analysers, additional lasers, and a reference detector. Research groups with special sample requirements can often be accommodated by changing the cell holder design or size.

Based on a special turntable with precision ball bearings and stepping motor, the Bl-200SM’s advanced design and quality construction guarantee precise measurements due to the wobble-free movement of the detector. The system is field proven in hundreds of laboratories and has become a light scattering research standard for macro-molecular studies and submicron particle sizing.

By taking advantage of the multiple inputs available on the BI-200SM’s proprietary digital correlator a new capability of the BI-200SM system was created. By adding an optical signal splitter to the beam of scattered light and a second detector it is possible to eliminate the effects of very high-speed interference from the detector(s). This Cross Correlation System provides remarkably clean data.
