A thermal module for pre-heating liquid flowing into a liquid chromatography column, includes a trough compartment with two ends, one of the two ends having an electrical socket, a first fluidic assembly, a second fluidic assembly, and a clamp assembly. The clamp assembly includes a rail configured to receive the first fluidic assembly. The clamp assembly includes a carriage slidably mounted to the rail and configured to receive the second fluidic assembly. The carriage is operable to establish a first fluid tight seal between the first fluidic assembly and a chromatography column received within the clamp assembly, and to establish a second fluid tight seal between the second fluidic assembly and the chromatography column. The clamp assembly is disposed within the trough compartment, and the first fluidic assembly is plugged into the electrical socket at the one end of the trough compartment.
