Until now, it has only been possible to heat multimode readers using temperature control, not to set them at ambient temperature or lower. This can cause problems for temperature-sensitive experiments, such as enzymatic assays, affecting the reproducibility of results over time. In addition, the experimental precision can be decreased by the plate heating up during measurements, even over just a few minutes. Tecan’s Te-Cool™ module for the Spark® platform, the first air conditioning system for a multimode reader, addresses this problem. This unique device can cool the measurement chamber, enabling it to be set at any user-defined temperature from 18 to 42 °C, guaranteeing stable conditions every time, in every lab, across every season, anywhere in the world.
