Abstract
This disclosure relates to a horizontal whole body chamber (HWBC) for conducting whole-body exposure analyses therein. The HWBC is configured to provide a uniform distribution of a test material within an air flow to achieve reliable whole body exposure. The HWBC achieves uniform mixing over short distance lengths to provide whole body exposure chambers that are practical for smaller animals and lessen the consumption of laboratory space.
Claims22
An enclosed chamber, comprising:
- a horizontal chamber tube operably connected at a proximal end to a first end cap and at a distal end to a second end cap, wherein the horizontal chamber tube comprises a material with a cross sectional dimension that defines a hollow space along the length of the horizontal chamber tube,
- the first end cap comprising an inlet and at least one Stairmand disk, and the second end cap comprising an outlet, and further wherein the inlet and the outlet are operably connected through the hollow space to allow passage of a test gas through the enclosed chamber and further wherein the enclosed chamber is configured to disperse an aerosol uniformly within 1 to 3 cm of the proximal end of the horizontal chamber tube.
