Abstract
A device for concentrating liquid specimens and the process of using the device. The device has a receptacle containing a membrane. The sample to be concentrated is placed in the receptacle on the upper surface of the membrane. A piston is then screwed down toward the upper surface of the membrane increasing the pressure above the membrane. The process for using the device involves supporting the device at a small angle from the vertical so that once the specimen has been concentrated to a given volume, the tilted membrane is exposed allowing air to reach the membrane and equalizing the pressure thereby rapidly decreasing any further concentration.
