Shimadzu CTO-20A HPLC Column Oven

A large-capacity, forced hot-air circulation-type column oven, the Shimadzu CTO-20A can regulate the temperature from 10ºC above room temperature to 85ºC. Rapid temperature equilibration allows complex temperature programs incorporating linear and/or step-wise increases and decreases in temperature.


  • Precise Temperature Regulation with a high-performance thermistor. Automatic fan-speed control varies with the set temperature to provide stable analysis that is not influenced by the ambient temperature.
  • Large Inner Space that can accommodate other system parts in addition to the column.
  • Information management with the Column Management Device (CMD).
