Description
DESCRIPTION Asbestos Reference Index 3 Grid 200 mesh with alphabetic and number codingReference Index Grid, Copper, Regular Bar, 100/vial Regular Bar Mesh: 200
Pitch: 127 microns
Hole: 115 microns
Bar Width: 12 microns Micron Locater Grids These grids are found to be very useful for AHERA studies. Clean and sharp lines. Index l is 75 mesh for the strong bars and each square is bisected in both directions with thinner bars. Reference/Finder Grids for Transmission Electron Microscopy A selection of TEM grids with reference patterns to enable relocating a particular grid area. Theses grids are known as reference, locator, finder or index grids. A number of different patterns have developed with either symbols or alphanumeric coding to quickly find a specific field. The locator or finder grids enable quick and easy checking of a particular feature at a later time or on another TEM. Exact grid square definition is a requirement in forensic and asbestos analysis. Another feature of the reference TEM grids is that when moving around on the grid, earlier found features or particles can be easily relocated. All reference grids are available in copper, some in gold or nickel.
