ABSTRACT:
This invention relates to an improved method and apparatus for preventing cross-contamination of biochemical test wells included in a microtiter test plate which comprises the covering of the biochemical test wells with a porous barrier that has been impregnated with an approximately 10% (W/V) solution of a solid, water soluble compound and then dried before use, the impregnating material being one selected form a group of chemical compounds consisting of inorganic acid phosphates, the acid salts of amino acids and the polycarboxylic organic acids which are relatively non-volatile, non-hygroscopic and non-toxioc to humans and bacteria while remaining effective to neutralize alkaline gases without attacking the barrier material.
