A stable column temperature is crucial for reproducible separations and constant retention times. Moreover, increasing the column temperature leads to a decreased solvent viscosity and therewith to a lower backpressure. Consequently, flow rates can be raised resulting in faster analysis times of your HPLC system. KNAUER`s column tempering solutions improve your separations.
The basic column thermostat is a software controlled heating department, designed for up to 8 columns depending on the size of the columns. Suitable for analytical und semipreparative columns in the peltier element controlled temperature range of 5–85 °C. Can be additionally equipped with a preheating cartridge.

Options for Pre-Column tempering
Pre-Heating Cartridges for Column Thermostat
Pre-heating cartridges can be installed inside the column thermostat or be remotly placed inside another heating element. Due to the internal volume and geometry the solvent is heated at the desired temperature. This avoids temperature profiles inside the column. Depending on temperature and solvent flow, a heating cartridge is recommended.
The inner diameter should be similar to capillaries used in the system to avoid any unnecessary volume contraction.
Rule of thumb:
For flow rates higher than 500 µl/min or temperatures above 50 °C, the use of a pre-heating cartridge is recommended.
