turning dosage wheel on the side of the container. When the cap is opened, the wheel is rotated clockwise in a single movement up to the stop point, which releases the dose. The user then inhales and closes the cap. Usage is monitored via a dose counter and reloading the dispenser is said to be easy. The patented multidose inhaler offers accuracy of dosing and dispersion over a wide range of flow rates


(RSD prototype <8%) and is said to meet EMEA and FDA requirements. RPC Formatec business development manager Thorsten Fischer said the company is currently seeking pharmaceutical partners to commer- cialise the system.


Small innovations One of the fastest growing areas of application for polymers in the medical sector is in diagnostics, where so called ‘lab-on-chip’ microfluidic devices are allowing complex analytical procedures to be automated. Such components are typically produced from two flat mouldings which are assembled to create a network of fine capillaries that draw the analytical fluids into the system and negates the effect of gravity.


Laser welding is frequently used to join these


components together and German laser specialist LPKF has developed a new system claimed to deliver the high levels of precision required. The PrecisionWeld system can create weld seams with a thickness of 100 microns and with a repeatability of 10 microns. Meanwhile, Wittmann Battenfeld will demonstrate production and overmoulded assembly of a micro fluidic
