Embodiment 1
[0014] Microgrid for transmission electron microscope in the present embodiment, it is made by acetone, n-pentyl acetate and collodion, and its weight percentage is:
[0015] Acetone 1% n-Amyl Acetate 39% Collodion 60%.
[0016] The production method of above-mentioned transmission electron microscope microgrid is: it comprises the following steps:
[0017] 1) Firstly, 39% by weight of n-pentyl acetate and 60% of collodion are mixed for preparation, then 1% by weight of acetone is added to the above mixture, and made uniform to make n-pentyl acetate , a mixture of collodion and acetone;
[0018] 2) In a petri dish equipped with distilled water, drop one drop of the prepared mixed solution of n-pentyl acetate, collodion and acetone, and immediately place a copper mesh with a diameter of 3 mm on the liquid surface of the mixed solution;
[0019] 3) After 3 minutes, a layer of film is formed on the liquid surface of the petri dish, and the filter paper is placed flat on it and ...
