Realistic Testing Equipment
RDD Online sells realistic throat models, Nephele patented mixing inlets, and USP-compliant Dosage Unit Sampling Apparatus equipment for pressurized metered dose and dry powder inhalers.
Three sizes of anatomically realistic mouth-throat models developed by Virginia Commonwealth University now allow investigators to more realistically evaluate drug capture in the mouth and throat, particularly when used in conjunction with a Nephele Mixing Inlet.
The Nephele Mixing Inlet (NMI) is designed to facilitate constant airflow and representative sampling though a cascade impactor while flow profiles through an inhaler are varied to simulate inhalation. NMIs are available to fit both the Andersen Cascade Impactor and Next Generation Impactor.
Delivered dose uniformity testing is described in both the US and European Pharmacopeia, and is conducted using Dosage Unit Sampling Apparatus (DUSA) for metered dose inhalers (MDIs) or dry powder inhalers (DPIs).
All equipment is supplied according to our Terms and Conditions of Sale.
