Sparging Liquid Aerosol Generator Data Sheet
The Sparging Liquid Aerosol Generator (SLAG) features a bursting bubble design that minimizes shear forces on particles being aerosolized. The particle suspension is typically delivered to the device via a peristaltic pump. The suspension travels downward through a narrow vertical needle and flows onto a porous stainless steel disk where it forms a thin-layered liquid film. The air is forced upward through the disk’s pores into the liquid. The multiple air streams emanating from the porous disk break the suspension into bubbles where the particles are contained. An expanding pressure gradient between the inside and outside of the bubbles causes them to burst, thus aerosolizing the particles. Particles and liquid not captured by the air stream are collected at the bottom of the glass vessel and play no further part in the aerosolization process. Thus, sensitive particles, such as microorganisms participate in the generation process only once and are not influenced by strong shear forces due to multiple cycles and recirculation.
