Microfiltration apparatus with radially spaced nozzles

摘要: The present invention relates to a multiwell apparatus for biological and biochemical analysis which provides separate collection of filtrate from each well, without cross-contamination therebetween. manifold plate having an array filtering wells, the wells being closed at its bottom by planar member providing filter support surface. A discharge nozzle passageway depends well (planar member) in direction normal thereto, with one such or port provided fluid communication well. Each these nozzles drain ports extends lower surface extent that it will enter into conventional multiwell, e.g., microtiter, alignment therewith mate sidewall aligned plate. In this manner, can be delivered as steady stream, manner would use pipette, rather than dropwise. ability quantitatively collect receiving options improved immunoassays, nucleic acid probe assays other test procedures.
