Thermal Uniformity with the xxpress® qPCR Thermal Cycler

qPCR is a molecular biology technique that utilises temperature cycles to amplify and quantify DNA. Thermal uniformity is essential when performing qPCR to ensure repeatable, reliable results. Undershoots can prevent reaction steps from reaching completion, whilst overshoots can cause the sample to degrade.  At BJS Biotechnologies we have developed the xxpress® qPCR thermal cycler which runs our patented heating algorithm to control the system thermals. This combined with its resistive heating technology and low thermal mass consumable is extremely effective in producing unbeatable thermal uniformity of ±0.3°C across the whole plate.
