A receptacle for the weighing-in of free-flowing substances has a fill opening, a tubular-shaped circumference wall, and a bottom part. The bottom part is connected to the tubular-shaped circumference wall, which it tightly closes off in the direction of gravity when the weighing receptacle is in its operating position. The weighing receptacle can be set on the weighing pan of a balance and can be filled like a beaker with free-flowing substances without allowing the latter to escape therefrom. The bottom part can be opened either by an outside force acting on the weighing receptacle and/or through the influence of a solvent acting on the weighing receptacle, forming an outlet orifice in the bottom part. The weighing receptacle, otherwise tightly sealed in the direction of gravity, can be flushed out with a fluid when the outlet orifice is opened.

The receptacle of claim 1, wherein: a smooth and/or coated surface is provided on the interior of the tubular-shaped circumference wall, the interior of the bottom part and the interior of the outlet orifice which face towards the substance. 10. The receptacle of claim 1, further comprising: a lid associated with the fill opening, for opening and reclosing thereof. 11. The receptacle of claim 10, further comprising: an inlet connector of the closure lid for fluids. 12. The receptacle of claim 1, further comprising: a medium for storing items of electronic information, at least one of which comprises a machine-readable identification field. 13. A method for preparing a solution of a free-flowing substance in a receiving container with a dosage-dispensing device and a balance, comprising the steps of: placing, on a weighing pan of the balance, a weighing receptacle comprising:a tubular-shaped circumference wall;a fill opening at one end of the tubular-shaped circumference wall; anda bottom part, connected to the tubular-shaped circumference wall, the bottom part initially tightly closing off a second end of the tubular-shaped circumference wall in the direction of gravity until an outlet orifice is opened therein;dispensing, from the dosage-dispensing device into the weighing receptacle, a prescribed quantity of the substance, the quantity of substance dispensed determined using the balance;seating the weighing receptacle on an inlet opening of the receiving container, opening the outlet orifice of the seated weighing receptacle, allowing the dispensed substance contained therein to flow into the receiving container, the opening step achieved by either:imposing a force on the weighing receptacle; orintroducing a fluid that dissolves a soluble closure body of the weighing receptacle, andflushing any dispensed substance remaining in the weighing receptacle into the receiving container, using a fluid as the flushing medium. 14. The method of claim 13, further comprising the steps of: storing information that is related to the dispensed substance and information related to the dosage preparation process, by recording the information to at least one of: an electronic storage medium of the weighing receptacle and an identification field of the weighing receptacle, andstoring the information recorded to the weighing receptacle by recording the information to at least one of: an electronic storage medium of the receiving container and an identification field of the receiving container.
