Technical Specifications

Technical notes:

Block temperatures - To provide thermal cyclers with the high performance and specificity required for the protocols of today, heated block design and program versatility are important features.

Incremental/decremental temperatures - Touchdown PCR protocols are where a higher temperature is required for the initial cycles than later cycles. This ensures that only highly specific product is created (amplified) during the critical initial steps. A decreased, less stringent temperature is then used by gradually decreasing the annealing temperature. The effect is a higher yield and more specific product. Therefore, to eliminate the need for programming lengthy error prone protocols, choose a thermal cycler which can automatically incorporate an incremental decrease/increase in temperature.

Incremental/decremental time - Long template PCR is the amplification of large fragments of DNA (e.g. 40kb lambda, 27kb Genomic). To ensure that the extension is fully complete after each cycle, the extension time is increased with each cycle to compensate for the increased product quantity and decreasing concentrations of reagents. As above with temperature, choose a thermal cycler which can automatically increase/decrease hold time at a given temperature.

Peltier technology - The peltier effect is used in many applications for the reliable cooling of sensitive high-temperature components without the need for refrigerants or compressors. Otherwise known as thermoelectric coolers, peltiers are a special type of semiconductor that function as a solid state heat pump. By applying a low voltage DC power source to one side, heat will be moved in the direction of the current (+ to - ). The heat is thus pumped from one side of the module to the other, so that one face will be cold while the opposite face will be heated. As this effect is reversible, peltier technology is the chosen method for heating and cooling the block in the best thermal cyclers on the market today.
