Gilder GA500 TEM aperture grid, 500um hole

Description

Gilder Grids TEM grids are precision TEM grids with a wide choice of patterns to support nearly all TEM applications. The Gilder Grids TEM grids are renowned for the unique fine mesh patterns, which extend to 2000 mesh delivering high transparency and small hole sizes. They are available in copper, nickel and gold. All Gilder Grids offered on these pages are made using a proprietary precision electro-forming process (plating). The Gilder Grids exhibit a smooth shiny side and a matte side and include well defined bars.

Many Gilder Grids feature either a rim mark, a center mark or both (see specifications). They tend to have a narrower rim and are thinner with smaller mesh sizes. The fine mesh grids with the thin bars and high transmission are even thinner. The fine mesh grids also include a wider 0.5mm rim to for increased stability.
The standard diameter of the Gilder grids is 3.05mm and they are packaged in black antistatic vials. Packaging is 100/vial for copper and nickel and 50/vial for Au. The extra fine bar 1000, 1500 and 2000 mesh are available with smaller packaging sizes.
