Abstract
A sample dispensing apparatus dispenses a sample from a container accommodating a sample such as blood or urea sampled for checking. This sample dispensing apparatus can prevent internal contamination of the apparatus due to dripping of the sample and abnormal sucking operations caused by drainage, condensation and fixing of the sample. The sample dispensing apparatus according to the present invention comprises a dispensing device for dispensing a sucked sample, a dispensing head provided in the dispensing device, and a disposable nozzle chip dismountably set on the dispensing head. In this apparatus, dispensing of a sample to child sample containers is performed exchanging the child sample containers with new ones. When the state, in which dispensing to the child container cannot be carried out, is continued for a prespecified period of time, the nozzle chip is automatically released from the dispensing head.
