ABSTRACT:
A multi-well filtration device for filtering a suspension comprises a filtration plate with a filtration chamber and a collecting plate with a collecting well. The filtration chamber is connected to the collecting well and a filter element is arranged between the filtration chamber and the collecting well. A separation layer is arranged between the filtration plate and the collecting plate adjacent to the filter element. The use such of a separation layer allows an easy detachment of the filtration plate from the collecting plate. The detached filtration plate can comfortably be transferred into an analysis device, in which the solid phase of the filtration chamber can separately be analyzed through the separation layer, without any replacement of the solid phase.
