HPLC column warmers are designed to allow to keep your columns at a constant temperature (known as isothermal) or utilize a series of temperature increases and constant hold temperatures (gradient elution). The use of HPLC column heaters allows for the separation process to be controlled and optimized, as heat generally reduced the time needed for separation. The amount of heat can generally be altered between a range of just above ambient temperature to over 300 °C. The heat you use will vary dependent on both the sample components and the stationary phase of the column.

| Description | The CTO-40S Slim Line column oven is ideal for saving space while maintaining excellent thermal stability. The new built-in dual leak sensors can detect small leakages of the mobile phase. Warming up the sample band and mobile phase in the column inlet tubing to match the set oven temperature is The CTO-40S Slim Line column oven is ideal for saving space while maintaining excellent thermal stability. The new built-in dual leak sensors can detect small leakages of the mobile phase. Warming up the sample band and mobile phase in the column inlet tubing to match the set oven temperature is possible with an optional preheating system. A switching valve can be installed for 2-column selction, and an additional valve can be added at the top of the oven for diverting flow to and away from an MS source.
Features: - The column oven will have time programming capability in stand-alone (320 steps) or system-controlled configuration for setting temperature ranges and oven ON / OFF.
- The oven can mount one manual injector, 2 flow-channel selection valves (one inside and one outside), a gradient mixer and a cell block of the conductivity detector.
- The oven can use a mixer recognition device to log the size of the mixer installed.
- The oven can communicate with an optional column management device to track column history.

Precise and stable temperature control of the mobile phase, column, and sample improves retention time reproducibility for superior The CTO-40C is a full size, high capacity oven that holds various sizes of columns. A switching valve can be installed for multiple column use in method development. Precise and stable temperature control of the mobile phase, column, and sample improves retention time reproducibility for superior qualitative and quantitative analyses. The built-in dual leak sensors detect tiny leakages of the mobile phase, leading to safer and more reliable performance.
Features: - The oven can use a mixer recognition device to log the size of the mixer installed.
- The oven communicates with up to two optional column management devices to track column history.
- The oven can mount 2 manual injectors, 2 inside flow-channel selection valves, a gradient mixer and a cell block of the conductivity or electrochemical detector.
