The material softens in Acetone and can be applied and gently pressed against a surface which was also wetted with acetone. Stripped off when dry, the replicas will hold a negative image of the replicated surface for inspection by scanning or light microscopy.\u003c\/p\u003e\u003cp\u003eFor TEM a second replica made by the evaporation of carbon and metal will produce a high resolution positive replica. Smoother and finer detail replicas require thinner replicating film. So the Triphan is better suited to the reproduction of highly sculptured surfaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eUse:\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis material is cellulose acetate of a thickness 35 micron. It is soluble in acetone. 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eStore at room temperature\u003cbr\u003e\u003c\/strong\u003e\u003c\/p\u003e","brand":"Agar Scientific","offers":[{"title":"Pack\/20","offer_id":49252443586750,"sku":"GTF-CAS35U","price":5000.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1784\/2811\/files\/GTF-CAS.png?v=1791508101","url":"https:\/\/proscitech.com.au\/products\/x20-cellulose-acetate-sheets-35um-thick-150-x-100mm","provider":"ProSciTech","version":"1.0","type":"link"}
