Reaction vessels
First Claim
1. Apparatus for effecting reactions, said apparatus comprising a plurality of reaction vessels for holding reagents, an electrically conducting polymer which emits heat when an electric current is passed through it, and control means for controlling supply of current to the polymer, the polymer being connectable to an electrical supply via the control means, wherein different currents can be supplied to heat each vessel of said plurality or a group of vessels of said plurality, independently from one another.

Abstract
Apparatus for effecting reactions comprising a plurality of reaction vessels for holding reagents, an electrically conducting polymer which emits heat when an electric current is passed through it, and control device for controlling supply of current to the polymer, the polymer being connectable to an electrical supply via the control device. The control device may be arranged such that different currents and therefore different temperatures can be achieved in each reaction vessel.
Certain novel reaction vessels are described and claimed. The apparatus are reaction vessels may be used in carrying out reactions which require multiple temperature stages such as amplification reactions such as the polymerase chain reaction.

20. A method of carrying out a chemical or biochemical reaction which requires multiple temperature stages;
- said method comprising placing reagents required for said reaction in a reaction vessel which comprises an electrically conducting polymer which emits heat when an electric current is passed through it, supplying current to said polymer so as to heat reagents to a first desired temperature; and
thereafter adjusting the current so as to produce the subsequent temperatures stages required for the reaction. - View Dependent Claims (21, 22, 38)
- said method comprising placing reagents required for said reaction in a reaction vessel which comprises an electrically conducting polymer which emits heat when an electric current is passed through it, supplying current to said polymer so as to heat reagents to a first desired temperature; and
- 25. A reaction vessel comprising a slide or a chip and an electrically conducting polymer which emits heat when an electric current is passed through it, said polymer being arranged to heat reactants on said slide or chip.
- 27. A reaction vessel comprising a container, a cap member, and an electrically conducting polymer which is arranged so as to heat reagents in the reaction vessel when current is supplied to said polymer, the cap member being formed so as to project into the container to reduce the capacity thereof and to create a space therebetween of substantially consistent proportions.
