The BRS 100i is microprocessor controlled instrument designed specifically for generating neonatal, infant, child and adult breathing patterns required for dose uniformity testing of nebulisers in accordance with ISO 27427:2013. It can also be used to generate the profiles required in USP <1602> for testing ‘Spacers and Valve Holding Chambers used with Inhalation Aerosols’. The unit can also be used in place of a standard vacuum pump with a cascade impactor and a Mixing Inlet to form a simple and inexpensive system for APSD studies.
Versatile: simple sinusoidal patterns to complex user-generated profiles
Inhalation and exhalation profiling
