Abstract: A fine-needle aspirator for collecting a biosample from a subject into a closed sterile system. The aspirator is adapted for use with a variety of needles and comprises a motor drive pump capable of continuous suction in a biosample collection system. The biosample collection system may comprise a biosample connector such as elastomeric tubing in communication with the needle and a collection space in a biosample container whereby a biosample collected by the needle may be transferred to the collection space. A flushing substance flushes the biosample through the biosample collection system. Additives may be added to the biosample after collection in order to treat, preserve or analyze the biosample.
