In order to address an inability to separate portions of a sample and/or substance, in some embodiments, methods and apparatuses for separating components and/or portions of a sample are provided. For example, a sample collection container may comprise two areas within the container, one which is configured to contain a first volume of the sample, and one which is configured to contain a second volume of the sample. A float device may be configured to seal the portion of the container collecting the first volume from the portion of the container collecting the second volume, after the former portion of the container has been filled. The sample collection container may further comprise a top cap configured to further seal the two portions of the container, and to prevent leakage and/or spilling of the sample from the sample collection container.
