Device for aligning slender object

The utility model relate to a device for aligning a slender object, preferably a cylindrical object and more preferably a detection tube (2) for extracting a sample and/or measurement data from molten metal in a gravity direction basically along a longitudinal axis of the device. The device comprises an input area (3), an accommodating area (8) and a guide device, wherein the input area (3) is used for inputting the object to an opening of the device; the accommodating area (8) is used for accommodating the object in the gravity direction basically along the longitudinal axis; the guide device extends in a direction from the input area (3) to the accommodating area (8); the guide device comprises a guide track (9) which is used for guiding the object from the input area (3) to the accommodating area (8); the guide device is a tank (4); and a gap is formed in a base plate of the tank (4).
