The Micromeritics Sub-Sieve AutoSizer (SAS) II determines particle size, surface area, and powder bed porosity by air permeability.
Developed as a direct and modernized successor to the widely used Fisher Model 95 Subsieve Sizer (FSSS), the Micromeritics SAS II utilizes a built-in computer and touchscreen to perform measurements easily and quickly in a laboratory setting or on a production floor. Data can be saved, printed, or exported electronically in a spreadsheet or PDF format.
The Micromeritics Sub-Sieve AutoSizer II generates “Fisher number” results highly consistent with those of its predecessor (the Fisher FSSS), using the built-in Fisher Mapping feature. This is a crucial point, as the air permeability technique and the FSSS have been used as a benchmark for decades in many industries. Many applications use historical data and quality control standards, and a modern source of comparable, repeatable results is necessary.
The air-permeability technique is well established for the measurement of the specific surface area of a sample powder. The specific surface area measured by this technique is a useful parameter in various industries such as pharmaceutical, metal coatings, paints, and even geological samples.
