The INHALER is a versatile adapter for the investigation and the development of all kinds of inhalers, MDI's, propellant gas sprays or pump sprays.

The central stage with the measuring chamber and the vacuum control unit can be adapted to the various needs by a flexible tool kit comprising

• a discus adapter - for the adaptation of discus shaped inhalers
• elongation front cylinder - expand the distance from the mouth piece to the measuring volume
• 90° elbow - simulated the human throat, customer specific designs can integrated easily
• pre-separator - removes coarse particles from the measuring chamber
• Venturi meter - for precise measurement of the air flow rate
• fine particle collector - collects the particles with highest efficiency at high throughputs and lowest pressure drop for subsequent (chemical) analysis.
• wash bottle - as with fine particle collector, but for medium throughputs
• vacuum pump - for the extraction

Air flow rate and inclination angle (for nebulizers) are controlled by software. Ambient temperature, humidity, air flow rate (via pressure) etc. are recorded.

As with the SPRAYER the WINDOX software allows for integrated or time resolved measurements with up to 2000 particles size distributions per second.
