A device for recovering magnetic particles trapped on a magnetic plug that has a bar magnet to retain the magnetic particles entrained by a liquid in which the magnetic plug is immersed, the device including a cap including a non-magnetic tube having a proximal end having an opening for the insertion of the magnet into the tube and a closed distal end, the tube to cover the magnet when it is inserted into the tube, a retention device to ensure retention between the cap and the magnet when the magnet is inserted into the tube, an extraction device provided with an opening to ensure insertion of the tube into the extraction device, the extraction device to cover the tube when the tube is inserted into the extraction device and to receive the particles trapped on the tube when the magnet is withdrawn from the tube, and a retention device to ensure retention between the extraction device and the tube. |
