  packed in anti-static vials

  These grids are available in molybdenum, titanium, aluminum and stainless steel 316. The grids are made by a high precision etching process. The thickness is approximately 25µm for Mo and Al, 15µm for Ti and 12µm for stainless steel. The pattern with the 350-400µm wide rim on the PELCO® grids provide greater stiffness and improves handling of the grids. All grids have a standard diameter of 3.0 to 3.05mm. Available styles are: square mesh, hexagonal mesh, double folding grids, tabbed grids, slotted and aperture grids. The square mesh and double folding grids have a center mark. For standard grid materials such as Cu, Ni and Au, please go to the PELCO® Grids page. Packaging: Mo, Ti, Al and Stainless Steel grids are packaged in 25grids/vial.

  100: Pitch 254µm; Hole Width 204µm; Bar Width 50µm; Transmission 65%
