Gilder Thin Bar Square 1500 mesh Copper Grid, Pack of 15

Details

In addition to our square and hexagonal mesh Gilder Thin Bar Grids, we are now able to produce a very fine mesh that values up to 2,000 lines/inch. There is an increasing need in TEM for support thin films, routinely carbon, as thin as 1.5 - 2.0nm. The pitch (the distance from the center of one bar to the center of the next bar) dimension in all grids remains constant, which allows them to be used as a lower magnification calibration aid. All new types, apart from one side being shiny, the other matt, have a large asymmetrical mark in the rim which gives the identification of which side the specimen is on. Grids are 3.05 mm overall diameter; 2.05 mm mesh area diameter.
