Copley Scientific will launch a low-capacity pump for inhaler testing at low flow rates at Drug Delivery to the Lungs (DDL) 19, to be held in Edinburgh, UK, from 10 to 12 December 2008.
The LCP5 is a small footprint, sound insulated, low-vibration vacuum pump designed for optimal operation at low flow rates.
All inhaled drug products are tested using the in-vitro technique of cascade impaction, which determines the aerodynamic particle size distribution of the aerosol produced.
Generating the appropriate air flow rate through the impactor during testing is an important performance factor.
The LCP5 is suitable for nasal sprays and metered dose inhalers (MDIs), which are tested at 28.3 (or 30) L/min, and nebulisers, which are typically tested at 15 L/min.
The pump, which includes an in-built variable flow control valve and the required hose fittings, is suitable for use with all USP and Ph Eur specified impactors.
This includes both the Andersen Cascade Impactor (ACI) and Next Generation Pharmaceutical Impactor (NGI).
Copley also offers a high-capacity pump for the higher, sonic flow rate testing requirements of dry powder inhalers (DPIs).
Experts from the company will be on hand throughout DDL to provide advice and discuss the full range of products.
