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.
A laboratory device adapted to subject a same rock sample to successive treatments without any intermediary handling, comprising, in combination, a chamber having a first part and a second part, said first and second parts being secured together, said first part being fitted with means for introducing a rock sample and liquid reagents into the chamber, means for regulating the temperature of the chamber and means for protecting the chamber from an inner overpressure, said first part of the chamber further comprising means for stirring liquid within the chamber, said stirring means comprising a bubbling gas inlet adapted to introduce gas bubbles into liquid contained in said chamber, the second part of the chamber being located under said first part, selective filtering means interposed between said first and second parts of the chamber and having a porosity selected for retaining organic matter contained in the rock sample and freed by the liquid reagents, means hermetically joining said first part of the chamber, said filtering means and said second part of the chamber, means for draining off liquid passing across said filtering means and collecting in said second part of the chamber and means for controlling the draining off of liquid from said chamber;
A method of separating organic material contained in a rock sample, which comprises introducing a rock sample, in particulate form, into a chamber via an open port;
