ABSTRACT:
A Leighton tube assembly designed for the growth of tissue cultures and their preservation comprising a tube, a cover slip and a means to close said tube. The tube, made from two injection molded pieces welded together, has a chamber toward its closed end and a neck towards its open end. The chamber has a wall with a flat portion which is separated from the open end of the tube by a dam located in the neck. The cover slip is molded of a plastic material which is both transparent and inert with respect to most chemical solvents. The cover slip has a culture segment which lies on said flat portion of the chamber wall when the slip is in its growth position and a handle. The handle is of a length which allows the positioning of a cap over the open end of the tube.
