3.05mm diameter, 0.7 mil thickness Copper (Cu), Nickel (Ni), Gold (Au), Copper/Palladium (Cu/Pd=CP) 3.05mm diameter, 0.7 mil (18μm) thickness
Material: Copper (Cu), Nickel (Ni), Gold (Au), Copper/Palladium (Cu/Pd=CP), Molybdnum (Mo)

A reliable support specimen grid source. Features: well-defined grid bars, maximum open area, and a matt/shiny side. Each grid is individually inspected. Newly introduced are copper grids with palladium plating. This plating offers better grid strength and avoids tarnishing.

arrow12Gold Plated Gilder Grids

3.05mm diameter, 0.7 mil (18μm) thickness (for all mesh), 50μm thickness (single hole and slot)
Material: Copper (Cu), Nickel (Ni)

To comply with the demands of immunogold labeling techniques, our Gilder copper and nickel specimen grid types, are now available with a gold plating (gilded) all with the same specifications as our regular grids. 24K gold is chemically deposited onto copper and nickel grids producing a uniform coating, with a gold thickness in the range of 0.10 to 0.25 microns. When doing autoradiography techniques, gilded grids have been used successfully for the localization and distribution of labelled compounds in specimens. The gold gilded grids decrease the risk of chemical reaction in many specimen treatment procedures, and is an alternative to the more expensive pure gold grids.

3.05 diameter, 0.8 mil thickness
Material: Copper(Cu), Nickel(Ni), Gold(Au)

Thin Bar Grids have been developed using a new technology to produce ultra-fine grids with thinner cross bars than regular grids. The result is equally firm specimen support but with 40% more open area for viewing maximum specimen surface area.

Type T600HH (hexagonal) and T600HS (square) represent our efforts to reduce the grid bar width (only 5 microns) enabling more of the specimen to be viewed. 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 3.05mm overall diameter; 2.05mm mesh area diameter.

arrow12Very Fine Meshes

**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.

arrow12TEM Specimen Supports in Molybdenum

We have extended our range of TEM grid materials to include four types, which are now available in Molybdenum. The new products are manufactured using a process known as chemical ‘milling’ (etching) instead of the more familiar technique of ‘electroforming’ (deposition) that is used in the manufacture of copper, nickel and gold products. Molybdenum is used principally in applications where it’s high temperature, hardness, expansion of coefficient and corrosion resistance characteristics are considered important. The material which is used has a purity of 99.9%.
