Abstract: A method of providing filled product bags of sterile and particulate-free fluid includes securing a product bag to one of a plurality of movable cradles, wherein the product bag has a bladder, a stem fluidly connected to an opening of the bladder, and a filter disposed in-line with the stem. After securing the bag, an inlet of the stem is connected to an outlet of a nozzle assembly and at least partially filling the product bag with a fluid through a nozzle of the nozzle assembly to create a filled product bag, wherein filling the product bag includes passing the fluid through the filter and into the bladder. After filling, the stem of the filled product bag is sealed at a location below the filter. The stem is cut at a location above the seal and below the filter.
