Since 15 years, the SensoQuest GmbH has produced high-quality thermal cyclers with the brand Labcycler for industry and public research institutes. The company is focused on the gold-plated silver blocks. Silver has thermal conductivity of 427 W/mK, much better than aluminum (237 W/mK). Low power consumption, low noise, fast heating and cooling rates during real operations and the cycling, as well as a cool down under the freezing point demonstrates the performance of the Labcycler. All this resulted in a long lifetime. A self-calibration system completes the Labcycler product line.
