Research Grade Light Scattering Instrument for Teaching Labs

Testa Analytical Solutions eK reports how the internationally respected Department of Chemistry at the University of Helsinki is using its BI-200SM light scattering goniometer for physicochemical characterisation of polymers.


Dr Vladimir Aseyev, a senior lecturer in Polymer Chemistry at the University of Helsinki said: "Based upon practical use of our BI-200SM light scattering goniometer we organise a course of lectures on light scattering for students as well as a laboratory practicum. These activities attract students and researchers from other departments such as physics, biology, pharmacy, food science and medicine."

Dr Aseyev added: "Simple design and easy alignment are the main features that differentiate the BI-200SM from other commercial light scattering instruments. In a combination with the user-friendly software, it is very easy instrument to demonstrate to students how the method and data analysis work as well as what are the limitations of other commercial instruments. The latter is especially important for the students, who continue their career in industry, where single angle light scattering detectors are more common. Recently, with the help of Testa Analytical we upgraded the computer, software and the motor for our BI-200SM. We received very professional advice as well as fast and clear technical support from Testa, who clearly understand the needs of universities and have always been most helpful."

The Bl-200SM light scattering goniometer is a precision research grade instrument designed for precise and accurate measurements. Based on a special turntable with precision ball bearings and stepping motor, the Bl-200SM's modular, automated design and quality construction guarantee precise measurements due to the wobble-free movement of the detector. As you would expect from a research grade system the BI-200SM can measure light scattering over a wide angular range (8° to 155° with 25 mm cells) and offers fine adjustment of measurement angles to 0.01° directly using a large, fine-control knob or PC-driven Motor control. Fine-screw vertical adjustment makes centre of rotation measurement easier when aligning cells. Precise repeatable data is ensured by automated heating and cooling of the sample cell using and standard external recirculating system. Field proven in hundreds of labs around the world the BI-200SM light scattering goniometer system is ideal for even the most demanding macromolecular studies and submicron particle sizing applications.
