Abstract: A method for taking a sample (22a) from a closed test tube (11) without removing the stopper (12) of the test tube. According to the method, the stopper of the test tube is pierced with a disposable piercing needle (13) through which the sample is taken to the sample receptacle (16) of the sampling device (10). From there the sample (22b) 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

Abstract: PCT No. PCT/FI89/00220 Sec. 371 Date May 31, 1991 Sec. 102(e) Date May 31, 1991 PCT Filed Dec. 1, 1989 PCT Pub. No. WO90/06526 PCT Pub. Date Jun. 14, 1990.The counting error due to variations in the counting efficiency as a function of the volume of the sample is corrected. The sample is placed into a sample container which is placed into a vertically positioned cylinder shaped counting chamber. Photomultiplier tubes are disposed on the opposite ends of the counting chamber. At least two of the following spectra are measured in the coincidence counting: the sum spectrum q observed by both of the photomultiplier tubes, the spectrum q(y) observed by the upper photomultiplier tube and the spectrum q(a) observed by the lower photomultiplier tube. The counting error is corrected by the correction coefficient obtained from these spectra.
