Design and Construction
The Small Sample Adapter consists of a cylindrical sample chamber and spindle, designed to provide a defined geometry system for accurate viscosity measurements. The sample chamber is made of high-quality materials, ensuring durability and resistance to corrosion. The SSA is designed to work with a temperature bath for precise temperature control, and the sample chamber fits into a flow jacket for temperature control. The adapter is also equipped with embedded RTD temperature sensors for direct readout of sample temperature.
Operating Principle
The Small Sample Adapter operates on the principle of rotational viscometry, where the spindle rotates at a precise speed, creating a shear rate that is proportional to the viscosity of the sample. The SSA’s rheologically correct cylindrical geometry ensures that the shear rate is uniform throughout the sample, providing extremely accurate viscosity measurements. The embedded RTD temperature sensors allow for precise temperature control, ensuring that the sample temperature is accurately measured and controlled.
