Breathing Simulators

From the generation of simple sinusoidal patterns as stated in the Ph. Eur. and USP for testing nebulisers and MDIs with a spacer/VHC, to complex user-generated profiles for improving in-vitro in-vivo correlations (IVIVCs), our range of Breathing Simulators can be used across a variety of testing applications and patient physiologies.

BRS 300i Breathing Simulator

Similar in design and operation to the BRS 200i, the BRS 300i has a larger volume of 0 mL – 5 L. It also features a maximum flow rate of 240 L/min (free flow) and a maximum acceleration of 25L/s2 (free flow) making it the ideal unit for the testing of MDIs and DPIs for improved IVIVCs.

  • 21 CFR Part 11 compliant

  • Stores and recalls methods

  • Powerful drive system for generating challenging profiles

  • Extensive data output options
