Thermoelectric cooler experiment

We had an exciting experiment last week in our BM605 lab. Students were asked to make a thermometric cooler using reverse peltier effect. We could make ice-cold water within minutes.

A peltier module, a CPU cooling fan, peristaltic pump, alluminium cooling block and a few tubes were all that was needed to do this magic. A Peltier cooler is an important component of the Thermal Cycler (also known as a Thermocycler, PCR Machine or DNA Amplifier) that is used to amplify segments of DNA via the Polymerase Chain Reaction (PCR).
