The invention is a prefilled culture medium bag with a gusseted base that is capable of standing in an upright position. The prefilled culture medium bag can be sterilized by irradiation. Or alternatively, the culture medium can be sterilized apart from the bag and subsequently placed inside the bag after the bag has been sterilized. In either case, the end product is a pre-sterilized and prefilled culture medium bag delivered to a laboratory for use. The culture medium bag is self-supporting and takes on the characteristics of a rigid container when filled. The culture medium bag is easy to open and reseal for introduction of a culture sample at the laboratory. After introduction, a sample can be incubated within the culture medium bag.

1. A prefilled culture medium bag, comprising:a culture medium; and a bag adapted to contain the culture medium, the bag comprising a pair of thin film plastic sheets, a lower region of the sheets being connected together and closed by a gusset, side edges of the sheets being bonded directly to each other without the use of a gusset so that the upper regions of the sheet may lay flat, one on top of the other, when the bag is either filled or not filled with the culture medium, and wherein an upper region of one sheet may be spread apart from the upper region of the other sheet in order to introduce the culture sample into the bag, and including a closure wire connected to the upper region of one of the sheets, the closure wire having a length that exceeds the width of the bag, in a manner so that the upper regions of the sheets may be rolled around the closure wire to reseal the bag after the culture sample is introduced.
