Abstract: Assemblies of a cap and a tube fixed to the cap are provided in which at least a portion of each assembly has a visual coding of color and/or indicia for use with one of different sizes of bottles at least in accordance with a height of the bottles from a closed bottom end to an open top end for engaging the cap of the assembly. In each assembly, the cap has a tube mounted to, or through, an aperture extending through the cap to extend a selected length enabling one end of the tube to reach or extend along at least a portion of an interior surface of the bottom end of any of the bottles of the height to which the assembly is coded for use therewith. Each of the caps has another tube or port to another aperture of the cap to provide an air vent.

Abstract: A plurality of caps are provided each with a visual coding of color and/or indicia for use with different sizes of bottles at least in accordance with a height of the bottles from a closed bottom end to an open top end for engaging each of the caps. Each of the caps has a tube mounted to, or through, an aperture extending through a top closed end of the cap to extend a selected length enabling one end of the tube to reach or extend along an interior surface of the bottom end of any of the bottles of the height to which the cap is coded for use therewith. The other end of tube is extendable to a bioreactor container. Each of the caps has another tube or port to another aperture of the cap to provide an air vent with an optional air filtering device.
