The present invention relates to a liquid phase transmission electron microscopy (LP-TEM) holder with integrated temperature regulation for operating with an associated transmission electron microscopy instrument providing an electron beam for imaging, the LP-TEM holder comprising a liquid phase sample receptacle (LPSR, 5) which may be made from two or more layers of materials, e.g. microchips, the LPSR providing a liquid compartment. The LP-TEM holder furthermore comprises an integrated temperature regulating unit (15), capable of regulating the temperature of the LPSR and liquid in the liquid compartment by means of a temperature measuring unit (16) capable of measuring a temperature in the liquid compartment. The LPSR is thermally isolated with a thermal isolating portion (30), with respect to an external environment and associated devices. The invention is particularly advantageous for providing fast temperature regulation and accurate steady state temperatures of one or more fluids to be imaged.
