Açıklama

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.

Standard Square Mesh

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

Gilder Finder Grids

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

Standard Hexagonal Mesh

3.05mm diameter, 0.7 mil (18µm) thickness 
Material: Copper (Cu), Nickel (Ni), Gold (Au)

Parallel Bars

3.05mm diameter, 0.7 mil (18µm) thickness 
Material: Copper (Cu), Nickel (Ni), Gold (Au)

Rectangular

3.05mm diameter, 0.7 mil (18µm) thickness 
Material: Copper (Cu), Nickel (Ni)

Double Grids (Oyster)

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

Double grids are used mostly in metallurgical applications for supporting thin metal foils. These grids have a curved securing tab which folds to the curvature of the 'sandwiched' grid. Four configurations are available:

Single Slot Grids (Oval Hole)

50µm thickness (single hole and slot)
Material: Copper (Cu), Nickel (Ni), Gold (Au), Molybdnum (Mo)

Single Slot Grids (Aperture Grids)

50µm thickness (single hole and slot)
Material: Copper (Cu), Nickel (Ni), Gold (Au), Molybdnum (Mo)

Gilder Thin Bar 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.

New Revolutionary Specimen Support Grids

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.

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.

TEM 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%.
