A novel technique of connecting two or more pumping modules under a laminar flow hood is described. The technique includes the use of a novel manifold which is specifically designed to enhance laminar air flow across the outlet port of the manifold when connected to one of the pumping modules. The manifold...http://www.google.com.au/patents/US4718467?utm_source=gb-gplus-sharePatent US4718467 - Pumping module arrangement and manifold
