TEM

Agar Scientific offers a range of TEM grid boxes with numbered holes for up to 100 grids. Boxes have a low susceptibility to charging and available in rectangular or rotating design. Individual grids can be easily accessed whilst ensuring most of the stored grids are protected from accidental disturbance. Most boxes are designed to be securely stacked with other boxes.

Standard grade TEM grids are available in copper, nickel or gold, or in copper with one side flash coated with palladium for identification purposes. All grids are available in 3.05mm diameter and some in 2.3mm diameter. All Agar grids are packed in tubes of 100, unless otherwise specified. A comprehensive table of grid parameters is available on request.

• Special metals: aluminium, molybdenum, stainless steel and titanium

Holey carbon films have many uses in microscopy but for certain applications the mesh sizes of standard TEM grids are too large to support the sample. Continuous carbon films can also be a problem due to the fact that the thin film can inelastically scatter electrons and contribute to background noise. Holey carbon films therefore are a suitable alternative. Holey carbon films have holes of various sizes up to 100µm. In addition to providing support, the increased image contrast in the regions of the holes compared to regions of film is also of benefit. Typical applications include biological and materials science and cryo-TEM.

• Available on copper, nickel and gold grids
• 200, 300, 400 mesh grids
• H7 finder grids
