ABSTRACT OF THE DISCLOSURE A device is provided for collecting and removing samples by vacuum suction created in a tube with an opening at the bottom. The sampling device has a part that receives a sample of material and a part with an outlet. A vacuum tube on one side of the device has an opening at the bottom thereof. The vacuum tube is connected to a device that creates a negative pressure in the vacuum tube. A connecting chamber connects the sample receiving device outlet with the vacuum tube opening. A part, usual- ly containing an orifice, is connected to the sample receiving part, such part permits air to enter the connecting chamber in such a way that a jet of air is formed under the opening in the sample receiving part. m is jet of air helps the material in the sample receiving part to move into the vacuum tube. The sample receiving part is preferably made of two tubes, one inside the other, both tubes having openings therein that in one posi- tion communicates such that sample material may travel through the openings. Inside the inner tube, angled partitions run from the opening upwardly to the opposite wall. The angled partitions facilitate removal of the sample material. This device allows an operator to insert a probe using power assisted machinery from a remote location and receive the sample at that remote location, preferably near the sample analysts equipment.
