Application Note for Leica EM HPM100 – Leaves were immersed in hexadecene and placed under a gentle (0.3 bar) vacuum for 10 minutes to evacuate the internal air spaces. The leaves were then trimmed to fit the carriers and placed in the 200 μm side of a 6 mm Type A specimen carrier. Free space was filled with additional hexadecene after which a 6 mm Type B specimen carrier was placed on top with the flat side down.
