ABSTRACT:
A laboratory device and method are adapted to subject a same rock sample to successive liquid treatments without any intermediary handling of the sample. The device combines a chamber comprising a first part fitted with an inlet for introducing a rock sample and liquid reagents into the chamber; a heater for regulating the temperature in the chamber and a plug fitted within an open port for protecting the chamber from an overpressure. The first part also comprises means for stirring the contents of the chamber including a liquid by introducing gas as bubbles into the liquid. A second part of the chamber is located under the first part and a selective filtering unit is interposed between the first and second parts of the chamber, the filter has a porosity selected for retaining organic material contained in the sample. A gas bubbling inlet is provided for introducing the gas into the liquid contained in the chamber and a valve controlled discharge opening is also provided for draining off liquid from the chamber.
