The present invention relates generally to the fields of chemistry and molecular biology. More particularly, the present invention relates to thermally-conductive compositions and reaction tubes for chemical- and biochemical-based analytical processing. Compositions and reaction tubes in accordance with the invention comprise at least one plastic and at least one compound having a higher thermal conductivity than the at least one plastic to result in compositions and tubes having increased thermal conductivity when compared to the at least one plastic alone. Such compositions and tubes are capable of facilitating rapid heat transfer in numerous heat transfer applications. The thermally-conductive compositions and reaction tubes are especially suitable for containing reaction constituents during thermal cycling of the polymerase chain reaction (PCR).
A thermally-conductive composition comprising at least one plastic chosen from at least one of polypropylenes, polyethylenes, polyesters, polyacrylics, polyamides, polycarbonates, and vinyl polymers and comprising at least one compound having a higher thermal conductivity than said at least one plastic, wherein said at least one compound is chosen from boron nitride, thermally-conductive polypropylene, aluminum oxide, titanium oxide, iron oxide, tin oxide, beryllium oxide, zinc oxide, aluminum nitride, boron carbide, silicon carbide, titanium carbide, graphite or carbon fibers, carbon powders, nickel powders, gold or gold coated powders, silver or silver coated powders, or combinations of nickel graphite or nickel gold additives.
A reaction vessel for chemical or biochemical reactions comprising at least one plastic and at least one compound having a higher thermal conductivity than said at least one plastic.
A PCR tube comprising at least one plastic and at least one compound having a higher thermal conductivity than said at least one plastic.
