Researchers from Eötvös Loránd University have used a BI-200SM research goniometer system from TESTA Analytical Solutions e.K. in Dynamic Light Scattering mode to determine the aggregate size of powders used in producing sintered bulk calcium silicate ceramics.
The Bl-200SM goniometer system is a precision research grade instrument designed for exacting light scattering measurements. Based upon a special turntable with precision ball bearings and stepping motor, the instrument’s, automated design and quality construction provide precise measurements due to the wobble-free movement of the detector.
Sol-gel synthesised ceramic powders were studied by Eötvös Loránd University researchers to determine their properties in relation with biomedical applications. Using light scattering data obtained using the system, they were able to identify the best bulk ceramics with good mechanical strength, low solubility and similar porosity to bone, allowing them to be used as long-term implants.
Designed and built for demanding research experiments, the Bl-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 an standard external recirculating system.
Field-proven in hundreds of labs around the world the BI-200SM suitable for even the most demanding macromolecular studies and submicron particle sizing applications.
