ABSTRACT:
A device is provided for extraction of samples of an aqueous solution in a substratum. A probe made up of a pyrometric capsule of porous porcelain has one end of lesser diameter to which is attached a tube of inert material. The tube is sealed hermetically by a rubber cap with two drilled holes. An adapted pipe is fitted into one of the drilled holes for connection to a vacuum pump, and a suction capillary is placed in the other drilled hole.
