Peltier accessories are small, solid-state devices, consisting of a semiconductor junction bonded to two plates to which a direct electrical current is applied and are widely used for temperature control. To run efficiently, they require a heat dispersal system to remove heat that builds up during operation. Using air instead of water to regulate the temperature, the Air-Cooled Peltier accessories provide scientists with greater efficiencies by eliminating the laborious procedure of monitoring recirculating water levels, adding anti-freeze and anti-bacterial mixtures to a water-cooling system.
For many assays it is critical that the temperature be constant throughout the sample analysis. The Air-Cooled Peltier accessories contain built-in magnetic stirring, which helps maintain thermal equilibrium throughout the sample by eliminating thermal gradients within the cuvette. The stir speed is regulated by an external control module and software. The software also enables scientists to rapidly specify the temperature they require for analysis. The excellent temperature control system has been proven to offer superior performance and reliability. Additionally, the accessories allow scientists flexibility to choose from a wide range of temperatures between 20º and 60º C, covering the biologically relevant temperature of 25, 37, and 50°C.
The new Air-Cooled Peltier accessories are available for the Thermo Scientific GENESYS 10 series, GENESYS 10 Bio, BioMate 3, BioMate 5, Helios series, UV1, Evolution 60, Evolution 100 and Evolution 300/600 UV-Visible spectrophotometers.
