ABSTRACT:
A growth container for laboratory organisms such as fungi, TB bacilli, yeast, virus or bacteria in which a well for the growth medium is spaced inwardly from an outer and higher wall. A lid snaps in place over the dish to substantially enclose the growth medium. An absorbent material, preferably a ring of filter paper, is placed in the space between the well and the outer dish wall to humidify the container when the material is wet, and to collect condensation from the lid which may include dangerous spores. Condensation is collected from a blocking ring on the underside of the lid by inversion of the dish and absorption onto a filter paper ring. An access opening in the lid permits material to be removed from or added to the growth medium with the lid only partially disengaged. The well may contain a single growth medium or a number of segregated growth compartments. A method of obtaining a slide specimen is described in which a slide member is placed over the well and the organism is grown until it adheres to the underside of the slide member. The organism is then severed and the slide member and adhered specimen removed from the container. Substantially undamaged specimens are thus obtained quickly and with safety.
