RBG professional

Generation of test aerosols from powders, pollen, and spores for operation up to 10 bar counterpressure, mass flow approx. 0.04 – 800 g/h

Low-concentration solid particle aerosols produced from powders are required for many research, development, and quality assurance applications and for calibrating particle measurement devices.

For more than 25 years, the RBG system has been used worldwide with great success for the reliable dispersion of non-cohesive powders such as mineral dusts, active pharmaceutical ingredients, pollen, etc., in the size range of < 200 µm and with a fine fraction of < 100 nm. Monolithic solid materials like blackboard chalk are finely dispersed with the highest dosing constancy.

The unique advantage of this dosing and dispersion system is that in the RBG system, mass flows range from approx. 40 mg/h up to approx. 800 g/h are dispersed with the highest level of dosing constancy.

RBG professional is pressure-resistant up to 10 bar counter pressure and can be operated with nitrogen as carrier gas.
