Abstract: A thermocycling device and method of operating a thermocycler instrument the instrument including a sample holder, at least one thermal cycling element, and at least one first and second temperature sensors, for causing the sample holder containing the at least one sample to undergo polymerase chain reaction amplification by repeated cycling between at least a denaturation heating stage and an annealing cooling stage. The first temperature corresponding with the temperature of the sample holder is monitored using the at least one first temperature sensor, and a second temperature corresponding with the temperature external of the sample holder is monitored using the at least one second temperature sensor. Based upon the first temperature and the second temperature, the power that is delivered to the at least one thermal cycling element of the instrument is dynamically controlled.

Abstract: An improved sample tube that includes a body portion having a longitudinal axis and a wall generally circumscribing the longitudinal axis. The body portion terminates in a distal tip having a dimple. The body portion includes at least one transparent portion (e.g., at the distal tip) that is adapted for transmitting light. The wail is configured for elastic deformation along at feast a portion of its length, including in a direction that is generally transverse to the longitudinal axis, so that it compressively and resiliently deforms and engages a wail defining an opening in a sample block of a PGR amplification instrument. The tube may be made by injection molding a polymeric material including a thermoplastic.

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 more multiple sample vessels are placed in between the module such that the vessels are subjected to temperature cycling by the modules. The sample vessels have a minimal internal dimensional 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.
