Abstract

A multi-layered cell harvester having a multi-layered top section and multi-layered bottom section with holes and channels formed in the multiple layers along with vacuum and wash manifolds is provided for removing, filtering and washing the contents from test tubes in a standard test tube rack. The novel multi-layered cell harvester precisely controls an equal volume of wash fluid or reagent to the test tubes and each of the filter areas on a sheet of filter paper areas on a sheet of filter paper by utilizing a wash fluid or reagent reservoir having a purge means and wash channels of equal length formed in the multi layers from the reservoir to the tip of each wash needle where the diameter of each wash channel is the same, or by increasing the diameter of some of the wash channels or a combination thereof. The multi-layered cell harvester can include provisions for separately handling radioactive materials and saving the mother liquid and wash fluids or reagents.
