Abstract
A filtration system for handling an array of filter wells which are open at the top and closed by a filter membrane at the bottom. The system includes a manifold chamber defined by side and bottom walls and having a support for the wells which carries the filter membranes above the bottom walls so that filtrate may be drawn through the membranes. A vacuum fitting is connected to the chamber so that a low pressure source may be applied thereto, and a sealing sheet extends over the wells and having holes aligned with the open tops of the wells so that when the low pressure is applied to the chamber, filtrate may be drawn through the membrane.
