ABSTRACT:
A device for dispensing a portion of a biological liquid from a sealed vacuum tube onto a microscopic slide or other suitable application wherein the device is formed from an open-ended elongate housing having a cannula mounted therein so as to extend in a longitudinal direction thereof with a first needle end located in the upper portion to pierce the stopper of a vacuum tube and a second needle end positioned in the lower portion of the housing. A protuberance is provided at the base of the first needle end which serves to act as a pump in conjunction with the stopper of a vacuum tube momentarily pushed thereagainst so as to force a predetermined portion of a biological liquid in the tube through the cannula and out of the lower needle end thereof.
