Inhaler

The INHALER is a versatile adapter for the investigation and the development of all kinds of metered dose inhalers (MDI), dry powder inhalers (DPI), nebulizers or more recent developments such as superfine mist inhalers (Soft Mist™ Inhaler | SMI). When combined with compact laser diffraction sensor HELOS/BR the system analyses the size distribution of droplet mists and solid aerosols with particles ranging from 0.25 µm to 875 µm.

The central components of the INHALER comprise – alongside a base unit in which the other components are integrated – the measuring chamber and the software-controlled vacuum control unit, which ensures precise control of the volumetric flow. Nebulisers with slanting mouthpieces can be vertically aligned with a tilt compensation feature in the central unit. A large selection of system components allows the system to be adapted to different application conditions and further analysis requirements.

Inlet side | Before the measuring zone

Mouthpiece – accurately fitting holders and mountings for applicators | individual mountings can be manufactured from silicone compound
Extension cylinder – for adapting the distance between the mouthpiece and the measurement volume (spacer)
90° glass pipe bend – simulation of the throat, horizontal installation position also with pre-separator
Pre-separator for DPIs – in order to separate the carrier material from the active ingredient component under measurement (Fine Particle Fraction | FPF)
