Main Features

This product is a convenient and versatile column temperature control unit especially useful in UHPLC separations.

For those separations being performed at elevated temperatures this unit provides pre-heating of solvents to stabilize and reduce temperature gradients throughout the resolving column. The separation temperature control is an often overlooked variable of concern especially in the rapid LC world of today. Reliable temperature control (which can be affected by fluctuations in laboratory ambient temperature) is an important variable to control in order to alleviate retention time variability.

Additionally, separations performed at elevated temperature will generally have lower operating pressures due to the reduction of solvent viscosity at these higher temperatures.
