Abstract
A membrane batch-processor system and method for the fluid treatment of a plurality of specimen containing membranes, such as membranes having specimens of DNA, RNA, and protein molecules deposited thereon, includes a receptacle having an interior cavity and a plug-like closure slidably received in the cavity. A membrane stack is assembled from a plurality of membranes to be treated and flow definers interleaved between the membranes to defined a membrane stack of alternate flow definers and membranes. The flow definers are preferable fabricated from an open-weave fabric-like material to define multiple fluid pathways across the opposite surfaces of each membrane. Fluid distribution plenums are defined between to the receptacle and closure so that treatment fluid introduced into an entry plenum will flow through the multiple fluid pathways across the opposite surfaces of each membrane to expose each membrane to the treatment fluid and effect time and fluid efficient treatment of the membranes.
