The Gilder grids are available in 50 to an unrivalled ultra fine 2000 mesh. The Gilder grids feature well defined grid bars, shiny (smooth) and matt side difference and are packaged in custom anti-static vials. They are made with precision electroplating technologies. An additional feature of the Gilder grids are the rim and center marks to aid in the orientation on the grid and identification of each side. Most Gilder grids have a rim mark and many grids also have center marks. Wide selection of grid styles to support virtually every application with standard diameter of 3.05mm. Available materials are Cu, Ni, Au, Mo and Cu/Pd. Thickness of Nickel grids is typically 35µm ±5µm.
Packaging:
Standard Cu, Ni or Cu/Pd, 100 grids/vial except special configurations which are listed accordingly with packaging of 25 or 50 grids/vial.
Thickness of Nickel grids is typically 35µm ±5µm.
Thickness of Mo grids is typically 25µm - 50µm.
Molybdenum is used principally in applications where its hardness, expansion coefficient, high temperature and corrosive resistance characteristics are considered important. Mo typical purity 99.9%, melting point 2617° C (4742.6°F).
