A thermal immersion circulator comprising a housing defining a cavity, a heater comprising a heating element, wherein at least a portion of the heating element is located within the cavity of the housing, a coupling assembly securing the heater within the housing, and a seal isolating the coupling assembly from direct contact with the heater. The heater comprises a side surface having longitudinal axis, a fluid inlet in communication with a fluid outlet, and a fluid heating portion located between the fluid inlet and the fluid outlet. The heater also comprises at least one seal located adjacent the outlet and a heating element wrapped at least partially about the fluid heating portion. The heating element comprises a plurality of resistive bands arranged on the tubular side wall such that a first portion of a resistive band adjacent the fluid outlet is longitudinally spaced further from the fluid outlet than an opposing second portion of the resistive band to reduce transfer of heat generated by the resistive band to the seal whilst heating the fluid substantially along a longitudinal length of the fluid heating portion.
