Introduction The high quality EM-Tec TEM support grids are designed as sturdy and stable support grids. They are available in a variety of materials to suit the application at hand. The materials are the standard copper, nickel, gold and molybdenum and additionally titanium, aluminium and stainless steel. There are two manufacturing processes used for the EM-Tec TEM support grids:
After manufacturing they undergo a proprietary cleaning process to reduce contamination issues. All EM-Tec TEM grids are inspected for 100% quality assurance. The thickness of the EM-Tec TEM grids results in a more rigid and stable TEM grid for specimen support and specimen support films. The 375um wide rim contributes to a greater stiffness and makes handling and transportation of the grids much easier than grids with a narrower rim. The EM-Tec high quality TEM support grids are packaged in anti-static plastic vials with vials of 100 grids for Cu and Ni. The EM-Tec grids made from Au, Mo, Al, Ti and stainless steel are packaged in vials of 25 grids. They all have the standard 3.05mm diameter. Available patterns are: |
