Sample collection device

A filtering device for use with a collection tube defining a storage volume therein, the filtering device comprising:

• a mouthpiece being substantially conical in shape and defining a channel configured to allow a sample to flow therethrough;
• and
• a filter at least partially positioned within the channel, wherein the filter defines a plurality of apertures configured to filter a sample passing through the channel, and wherein when the filtering device is coupled to a collection tube the filter forms a flow path between the storage volume and the channel.

A sample collection device comprising:

• a collection tube at least partially defining a storage volume therein;
• a filter positioned at least partially within the collection tube and configured to subdivide the storage volume into a first portion and a second portion, the filter including a first, open end, and a second end opposite the open end, where the second end includes an end wall and at least one side wall extending from the end wall toward the first end, wherein the end wall defines a first plurality of apertures defining a second effective width, and wherein the side wall defines a second plurality of by-pass apertures defining a first effective width, wherein the first effective width is smaller than the second effective width, and wherein each aperture of the first plurality of apertures and each aperture of the second plurality of apertures extend between and are in fluid communication with both the first portion and the second portion of the storage volume.
