Abstract
A method for taking a sample from a closed test tube without removing the stopper of the test tube. According to the method, the stopper of the test tube is pierced with a disposable piercing needle through which the sample is taken to the sample receptacle of the sampling device. From there the sample is dispensed with a dispenser needle. The sampling device comprises an adapting element for fitting the test tube, with the piercing needle first, to the sampling device, a cup-like sample receptacle and a suction device for drawing the sample that is in the test tube into the sample receptacle.
