Small-scale powder disperser TSI - SSPD 3433

dispergator-pevnych-castic-perex.jpg TSI Model 3433 Small-Scale Powder Disperser is a compact and portable device for dry dispersion of solid particles in gaseous environment. It employs a turntable with a Venturi tube for dispersion of small (milligrams) amounts of dry powder. A Venturi tube creates sufficient shear forces to deagglomerate entering aerosol particles. The disperser generates a high quality and time-stable particle dispersion of a defined size range and concentration.

Specification

  • dispersion of solid particles of size ranging from 1 µm to 50 µm (aerodynamic diameter) 
  • Venturi tube flow rate is 16.5 litre/min
  • output particle concentration from 0.3 to 40 mg/m3
  • flow rate of carrier gas ranging from 12 to 21 litre/min
  • accessories: device for cleaning, dehumidification and pressure control of the input air

Typical applications

  • generation of aerosols for toxicology studies or for pharmaceutical industry
  • generation of tracer particles for gas flow studies
  • dispersion of calibrated particles (PSL) for validation measurements of particle sizers
  • dispersion of powder particles for measurement of their size
  • re-dispersion of particles deposited on membrane filters intended for air quality monitoring
  • generation of solid particles for research into deposition in environmental engineering
