A biopsy instrument for use with an endoscope includes a rigid cylindrical end attached to the distal end of a flexible arrangement of tubes. The rigid end comprises a cylindrical body having a cavity therein and said cavity extending towards the distal end of the body and being of a size sufficient to hold plural samples therein. Inside the body is a knife and suction generating device for drawing a biopsy sample into the cylindrical body and cutting it with the knife. Furthermore, a plunger is arranged coaxially with the knife for then pushing individual biopsy samples of a plurality into the distal end cavity of the cylindrical body.
