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 ast, precise temperature control. Thermo Scientific™ Peltier Accessories for the Thermo Scientific™ Evolution™ 200 Series and 300 UV-Vis Spectrophotometers provide thermostatting and ramping with precise temperature control between 0°C and 110°C.

Precise Thermostatting

Re-circulating water provides 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. 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.


Temperature Ramping

Thermo Scientific™ INSIGHT™ Software takes control of the PCCU1 and allows you to implement programmed temperature ramping with multiple ramp and hold cycles.  Add a thermocouple and thermocouple hub and you can monitor the exact temperature in each cell as you perform heating and cooling cycles to study

  • DNA denaturation and renaturation or other complex temperature programmed experiments using INSIGHT 2 Bio software.
  • Maximum ramp and hold cycles per experiment 20
  • Maximum ramp rate 20 °C per minute
  • Minimum ramp rate 0.4 °C per minute


Peltier Accessories for the Evolution 200 Series and 300 UV-Vis Spectrophotometers utilize circulating water as a heat source for heating and a heat sink for cooling.  The PCCU1 controller unit provides the flow or recirculating water, utilizing its own heat exchanger to keep the water close to room temperature. Stirring control for either single or 8-cell Peltier cell holders is provided when you place a micro-stir bar inside the cuvette.  Access temperatures from 0°C to 110°C with fixed temperature thermostatting from the control unit, and with ramping controlled by INSIGHT software on Evolution 200 Series UV-Vis Spectrophotometers.

Computer control and monitoring of the block temperature is possible with INSIGHT Software for the Thermo Scientific™ Evolution 201, 220 and 260 Bio UV-Vis Spectrophotometers.  This includes temperature ramping, variable temperature kinetics and DNA melting applications with optional INSIGHT Bio software.

With the Evolution 300 UV-Vis Spectrophotometer, thermostatting is achieved using the interface on the PCCU1 control unit.  Temperature ramping is not supported.

Choose one of our temperature probe options to monitor the temperature inside a single cell on any Evolution Spectrophotometer or up to 8-cells using INSIGHT Software on the Evolution 200 Series UV-Vis Spectrophotometers.
