Copley Scientific will display its DFM3 flowmeter at Drug Delivery to the Lungs 20 (DDL20), which takes place from 9-11 December 2009 in Edinburgh, Scotland.
The DFM3 is designed specifically for inhaled product testing.
A defined, constant air flow rate is required for tests specified in the US and European pharmacopoeias for all orally inhaled and nasal drug products (OINDPs), making a reliable and accurate flowmeter essential.
The DFM3 is based on its predecessor, the DFM2, but has many new features.
These include an expanded range, improved accuracy, and an RS232 port for easy external interfacing and simplified test setup.
The DFM3 is calibrated for flows in the range 15 to 100 l/min and is suitable for testing all OINDPs, including nebulisers.
At +/-0.75 per cent of full scale deflection, its accuracy is far better than its predecessor.
Flow is determined by measuring the pressure drop across a venturi, making the measurement method extremely robust and reliable, perfect for the everyday rigours of the analytical laboratory.
Furthermore, a new venturi design minimises the flow resistance and since the DFM3 is calibrated on the basis of outlet flow, there is no need to correct for any pressure drop across the meter.
Copley Scientific will exhibit the DFM3 for the first time at DDL20, where experts from the company will answer questions about its products.
A specification for the new flowmeter is also available.
