This invention is a convenient device for the enumeration of micro- organisms in liquids or suspensions. It consists of a plastic screw capped container having septa, for the division of the sample into appropriate volumes, and Durham tubes moulded in. It contains a sterile growth medium in lyophilised, powder or tablet form. The container is aseptically filled with sample to a line marked on its side, agitated to dissolve the medium and layed flat on a plane surface. It is then rotated through 90 DEG about its long axis so that the desired volumes of sample are separated into their respective compartments. The Durham tubes are designed so that air escapes from them during this operation. Incubation may begin immediately using a portable incubator if necessary. The device was conceived with potable water bacteriology in mind but many other possible applications exist.

The invention relates to a design of an interface plate (101) between a microfluidic cartridge (100) and an instrument (102) for fluid actuation in the disposable cartridge. Pneumatic actuation is carried out through a reversible pneumatic interconnection between instrument and cartridge. Pneumatic drivers are integrated in the instrument for a low cost and reliable solution. The actuation of the fluid in the cartridge is achieved by a flexible membrane (105) attached to the major surface of the disposable cartridge forming closed compartments only when attached to the instrument. The pressure, in these compartments determines the deflection of the membrane which in turn actuates the fluid. This approach takes advantage of the high power and large stroke of pneumatic actuation while at the same time keeping the disposable cartridge simple and low cost and allowing easy introduction of other physical transport across the interface plate, like heat or acoustic vibration.
