Improved methods and devices using reduction of pressure for removing ethanol from filters in a fluidic or microfluidic system in point of care devices involve filters that are solid state extraction filters used to capture and/or concentrate nucleic acids prior to further downstream processing such as amplification by polymerase chain reaction. The method uses the induction of negative pressure with respect to atmospheric pressure to improve the efficiency of the ethanol removal process.

Vacuum-assisted drying of filters in microfluidic systems

A microfluidics device has one or more bubble diversion regions. Problems associated with the generation of air bubbles are avoided in a microfluidics device such as a cartridge, for use with a point of care (POC) diagnostics device, the cartridge being able to carry out downstream processing such as polymerase chain reaction (PCR) and/or nucleic acid capture. The bubble diversion region has a lower flow resistance than the flow resistance of an area of interest.
