THERMOCYCLER AND SAMPLE VESSEL FOR RAPID AMPLIFICATION OF DNA
First Claim
1. A thermocycler for subjecting one or a plurality of samples to rapid thermal cycling comprising:
- at least one pair of thermoelectric modules each having an interior module face for heating and cooling one or a plurality of sample vessels each containing a sample;
wherein the thermoelectric modules of each pair are positioned such that;
the module faces of the thermoelectric module pair are in substantial opposition to each other with an interior sample holder between the opposing module faces for receiving said one or a plurality of sample vessels; and
a controller electrically connected to each pair of thermoelectric modules for regulating the temperature so that any sample vessels placed within the sample holder experience uniform temperature cyclings;
wherein the sample holder includes one or more openings for receiving the sample vessel, each opening having a shape so that the sample vessel is deformed upon entry into the sample holder openings.

Abstract
A thermocycler apparatus and method for rapidly performing the PCR process employs at least two thermoelectric modules which are in substantial spatial opposition with an interior space present between opposing modules. One or multiple sample vessels are placed in between the modules such that the vessels are subjected to temperature cycling by the modules. The sample vessels have a minimal internal dimension that is substantially perpendicular to the modules that facilitates rapid temperature cycling. In embodiments of the invention the sample vessels may be deformable between: a) a shape having a wide mouth to facilitate filling and removing of sample fluids from the vessel, and b) a shape which is thinner for conforming to the sample cavity or interior space between the thermoelectric modules of the thermocycler for more rapid heat transfer.
