Large-capacity, forced hot-air circulation units, the CTO-20A/20AC HPLC column ovens precisely regulate the temperature around the column. Automatic fan-speed control varies with the set temperature to provide stable analysis that is not influenced by the ambient temperature.
CTO-20A - Precise Temperature Control
A forced-air circulation-type column oven, the 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
The interior of the oven is precisely regulated with a high-performance thermistor. The temperature is calibrated at two different temperatures to ensure a high level of temperature accuracy.
Large Inner Space
In addition to the column, other system parts can be accommodated.
- Manual injector
- Gradient mixer
- High-pressure flow-line selection valves (2-position/6-port valves or 6-position/7-port valves, two in total)
- Conductivity-detection cell block
- Pre-or post-column reaction coil
