Micromeritics SAS II

Sub-Sieve AutoSizer (SAS) II – Air-Permeability Particle Size and Surface Area Analyzer

The Micromeritics Sub-Sieve AutoSizer (SAS) II provides rapid, accurate measurement of particle size, surface area, and powder bed porosity using the air-permeability method. Designed as the modern successor to the classic Fisher Model 95 (FSSS), it delivers equivalent “Fisher number” results with enhanced automation, touchscreen control, and built-in data reporting.

The SAS II features high-precision mass flow control, dual pressure transducers, and live data visualization, generating results within minutes. Fully compliant with ASTM standards B330, C721, and E2980, it’s ideal for both laboratory and production environments where reproducibility and speed are critical.

At Prisma Scientific, our specialists offer setup, training, and method optimization to ensure accurate, consistent air-permeability particle sizing aligned with industry benchmarks.
