Abstract

An improved laboratory chamber apparatus capable of carrying out multiple laboratory processes including hybridization, cell growth, and chromatographic separations, among others, includes a low profile base having a minimum volume chamber positioned therein. The chamber includes a selectably removable cover which is capable of providing access to and sealingly closing the hollow chamber. In the preferred embodiment, the cover is disc shaped so as to be able to sealingly engage a side wall of a low profile hollow cylindrical chamber and is insertable into the chamber to an adjustable depth to minimize the chamber volume, while allowing a variation of that volume depending upon the number of filters, membranes, or other accessories placed in the chamber. The hollow cylindrical chamber further includes opposed input and outuput ports, the input port providing for measured input of experimental solutions, wash solutions, etc., and the output port selectably providing a partial vacuum to the chamber, as well as providing for removal of solutions positioned therein. A support member extends vertically from the base to provide a means for mounting input and output apparatus to be used in…
