1. Apparatus for use with an electron microscope and for receiving a liquid sample and/or in-liquid sample droplet, the apparatus comprising:
a pair of parts which, in use, are disposed in abutting relation to one another to define a cell for use with said microscope, the cell having: disposed on opposite surfaces thereof, a pair of windows, the windows being arranged in spaced relation to one another; to define: a viewable interior volume of the cell at the region of overlap and the height of a cavity; the cavity communicating with the viewable interior volume of the cell; the volume of the cavity, in combination with the viewable interior volume, being larger than the volume of the droplet, the spaced relation being determined by additional opposite surfaces with contact area between them less than or equal to 0.1 mm2
wherein each of the bodies defines a surface in which the window of each body is defined; and
wherein at least one of the bodies defines a surface in which the height of the cavity of such body is defined.
