Abstract
A disposable sample trap system having a cylindrical hollow sample trap body formed with a bottom end wall and an upper open end and with multiple dividers extending across the hollow of the body to divide the hollow of the body into a plurality of chambers, a cap rotatably attached to and sealing said open end of the trap body, and inlet and outlet conduit attached to an opening in the cap to allow for passage of fluid and samples through the cap opening into one of the plurality of chambers which is aligned with the opening and subsequently out of the trap, wherein there are narrow slots in the dividers to fluidly connect the inlet conduit to the outlet conduit through the plurality of chambers so that when the outlet conduit is connected to a vacuum source, the vacuum causes fluid and samples to be drawn into the one of the plurality of chambers through the inlet passage while allowing the fluid entering into the one of the plurality of chambers to pass through at least one of the narrow slots to the outlet and trapping the sample in the one of the plurality of chambers, since the sample cannot pass through the slot.
