Abstract

Abstract A device for making a culture of micro-organisms has a container having an open end and means to seal the open end of the container. A second seal divides the container into a first compartment for a liquid culture medium remote from the open end of the container and a second compartment adjacent the open end of the container. A removable elongated member in the container has a portion extending through the second compartment and into said first compartment and removably engaging the second seal to seal liquid culture medium in the first compartment. A culture medium secured to a portion of said elongated member lies in the second compartment. Preferably the sides edges of the elongated member are tapered adjacent its inner end and a portion of the elongated member in the second compartment carries one or more solid culture mediums. Advantageously the second seal member is tapered to guide the elongated member through the center thereof.
