SASS 3010 Manual Particle Extractor

The SASS® 3010 is used to extract and transfer to a small fluid volume, aerosols captured by Research International’s electret filters. Captured particulates can be difficult to remove because induced dipole fields create a strong holding force and must be neutralized. Once particulates have been released, they must then be removed from within the fibrous filter matrix and collected in a small amount of sample fluid. These processes are efficiently performed in a matter of 1 to 2 minutes using the SASS 3010 Particle Extractor.
Extraction efficiencies have been found to be in the range of 70 to 80%.

SASS 4000 Concentrator & SASS 4100 Collector

1. The SASS 4000 is a highly efficient, high-volume aerosol concentration device.

3. Typical application area which involve the monitoring or collection of airborne plant, animal or human pathogens.
4. 325 LPM sampling rate; 30,000 hour fan life

But aerosol sample analysis is frequently plagued by four problems –

1. The targeted pathogen is present at a very low concentration
2. The collection process involves too small an air sample to be statistically valid
3. The temperature is below freezing; and/or
4. Available bioassay methods are not sensitive enough.
