Abstract
A device for drawing a small representative sample of air from a laminar flow air stream, such as that flowing through a clean room, is provided, which comprises a gridwork of evenly-spaced tubes having regularly spaced orifices to sample representatively a laminar flow stream of air to determine the number of particles therein. The gridwork of tubes is sized and configured to leave the laminar flow of the air stream substantially undisturbed.
