Abstract
Sample filtration devices are provided. The devices can comprise a filter membrane positioned between an input and output substrate and joined using an adhesive layer. The filter assembly can be used with various sample collection and dispensing devices, such as a flexible container, a bulb pipette, a micropipette, etc. Applying pressure to the filter assembly, e.g., using a flexible container, a bulb pipette or a micropipette can force the fluid through the filter membrane and onto a test strip or cartridge.
