Precise Thermostatting

Peltier Accessories for the Evolution UV-Visible Spectrophotometers utilize re-circulating water as an effective heat sink to allow the Peltier element to heat or cool the block over a wide temperature range. The single-cell holder can reach as low as 0 °C and as high at 110 °C. Thermo Scientific offers 3 Peltier options to cover many possible applications, including a multi-cell unit. Stirring control for the single cell holders is provided when you place a micro-stir bar inside the cuvette. Unlike thermostatting with a traditional re-circulating water bath where a large volume of liquid must be heated or cooled, heating or cooling the cell holder with the Peltier effect means more rapid and more precise temperature control. Choose between water or chemical coolant to best fit your needs.

Temperature Ramping

Thermo Scientific INSIGHT Pro Software allows you to control and monitor the block temperature of the Peltier unit and allows you to implement programmed temperature ramping with multiple ramp and hold cycles and variable temperature kinetics.  Add a temperature probe hub and probes, and you can monitor the exact temperature in each cell as you perform heating and cooling cycles. The Insight Pro software also includes pre-set methods that can be used to study DNA denaturation and renaturation or other complex temperature programmed experiments.
