覆膜用醋酸乙酯薄膜
【产品详情】 此醋酸乙酯薄膜为复制样品表面提供了快速方便的方式,尤其是复制无法做切割处理的大样品表面。薄膜可溶解于丙酮,在丙酮中很容易变软,直接吸附于事前已用丙酮湿润的样品表面,当薄膜干燥后直接撕下来即可获得样品表面信息。复样表面喷碳后,可将薄膜溶解于丙酮中去除。喷碳后的复样可直接在TEM、及SEM中进行观察。覆膜的厚度有35um,50um及75um三个厚度可选;包装为20片/包。具体使用方法:A piece of the replica material of a size suitable to cover the area to be replicated is cut from the sheet. A drop or two of acetone is placed on to the specimen surface and the replica film immediately applied (allowing surface tension forces to pull it down no pressure is required). The film should be left to dry for about 10 minutes when it will separate very easily from any reasonably flat surface. It can then be stretched between two pieces of cellulose tape, structure side outwards, wrapped round a microscope slide, and placed in a vacuum coating unit for shadowing and carbon evaporation. The required area is cut out from the film, and laid, carbon side up, on to microscope grids on a wire mesh standing in a dish of acetone, with the acetone just touching the bottom of the mesh. After one hour, remove the grids from the mesh and wash individually in acetone before drying. 产品详细价格及资料,请登录电镜耗材在线商城网站查看。
