Folding double mesh TEM grids

Folding TEM grids are also known as double or oyster grids. They are particularly useful for retaining thin foils and sections which are too thick or curled to properly adhere to the grid bars of a standard grid. The latch closure bends to enable the specimen to be securely sandwiched between the two halves of the grid.

For routine applications at ambient temperatures these grids are available in copper, nickel and gold.

For specialised applications, including high temperature, work we also offer these grids in molybdenum, titanium, and stainless steel.
