Abstract
A manifold block and valving system using the manifold block are provided, which are used for conducting chemical reagents, solvents, and other fluids. The manifold block includes a 'straight-through' common passage in fluid connection with several entry ports, including also a number of projections in the common passage in the vicinity of the entry ports. These projections partially obstruct the fluid flow, causing a turbulence that provides a washing action in those port regions. The manifold may be constructed of a photosensitive glass ceramic such as Fotoceram.TM. which consists of a number of layers which have been processed to form the manifold block, or of other suitable materials such as silicon.
