ABSTRACT:
An apparatus for filtering multiple biological samples using a filter membrane is disclosed. The apparatus comprises a well plate having at least one well adapted to contain the sample media. The apparatus further comprises a vacuum-clamping feature for placing the filter membrane in sealable contact with at least one well of the well plate. The apparatus further comprises a vacuum sampling feature for drawing the sample media contained in the at least one well into contact with the filter membrane. The apparatus further comprises a first vacuum chamber for providing vacuum to the vacuum sampling feature. The first vacuum chamber is an integral part of the apparatus. The apparatus further comprises a second vacuum chamber for providing vacuum to the vacuum clamping feature. The second vacuum chamber is also an integral part of the apparatus.
