O2k-Peltier Temperature Control

O2k-Catalogue

Description O2k-Peltier Temperature Control: Built-in electronic thermostat controlling temperature for two O2k-Chambers in the range of 4 to 47 °C; ±0.002 °C (at room temperature). Continuous recording of the O2k-Copper Block temperature with DatLab. Temperature change from 20 to 30 °C within 15 min; cooling from 30 to 20 °C within 20 min. Integral component of the O2k-Main Unit. The electronic temperature control of the O2k replaced the conventional water jacket.

Lower limit of experimental temperature

O2k-Series E and upwards have a more efficient temperature management system compared to previous series. At a room temperature of 21.1 °C a stable Peltier power of about -83% was reached after about 1:05 h from setting the block temp. from 37 °C to 0 °C. Capek Ondrej 14:36, 4 February 2013 (CET)
The O2k is specified for a chamber temperature down to 4 °C at 25 °C room temperature and down to 2 °C at lower ambient temperature, see test experiments on O2k-Specifications. Lower ambient temperature does not necessarily mean a "cold room". For a chamber temperature of 2 °C, an air conditioned room is sufficient.
For experiments at 0 °C, the O2k can be exposed to ambient temperatures down to just above 0 °C (all the electronic components are rated at least down to 0 °C, but 0 °C room temperature should be avoided due to condensation concerns). For low room temperatures close to 0 °C, some means of humidity control should be used.
With O2k-Series D a stable chamber temperature of 0 °C was obtained at a room temperature of about 14 °C. The cooling power of the Peltier element reached 95% of maximum.
