Temperature control and sample stirring are important for many UV-Visible analysis methods. Peltier thermostatted accessories outperform traditional heater/chiller units to deliver superior performance with compact integrated design, simple set-up, and fast, precise temperature control. Thermo Scientific™ Peltier Accessories for the Thermo Scientific™ Evolution™ 200 Series and Evolution 350 UV-Vis Spectrophotometers provide thermostatting and ramping with precise temperature control between 0 °C and 110 °C.
Peltier Accessories for the Evolution 200 Series and Evolution 350 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. The 8-cell holder can be cooled to 5 °C and heated to 100 °C. Stirring control for either the single or 8-cell Peltier 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.
Thermo Scientific™ INSIGHT™ Software allows you to control and monitor the block temperature of the PCCU1 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. Optional INSIGHT 2 Bio software can be used to study DNA denaturation and renaturation or other complex temperature programmed experiments.
