The KNAUER AZURA CT 2.1 is a cost-effective column thermostat designed for precise and stable temperature control in HPLC applications.
The instrument uses a microprocessor-controlled Peltier element, enabling both heating and cooling in the range of 5–85 °C. Its high temperature stability allows for programming linear and non-linear temperature gradients, improving separation performance.
For advanced applications, the system can be optionally equipped with an eluent pre-heating cartridge, ensuring consistent temperature conditions, improved selectivity, and better peak shapes.
Its compact design supports flexible integration and accommodates multiple columns.
