Square mesh
The standard grid type for a wide range of TEM applications a range of mesh sizes from 50 – 600.
Hexagonal mesh
An excellent alternative to the square mesh grid pattern. A hexagon pattern gives greater strength making it a good choice for routine use.
Fine hexagonal
Exceptionally fine mesh from 1000 to 2000. Can be useful for viewing particles for cryo-TEM.
Finder
Our support films are available on a range of finder grids enabling return to a previously viewed location on a thin electron transparent support.
Slot
Useful as a support for serial sections where grid bars would obscure section detail. Select from the range of slot sizes to suit the width of the sections
Parallel bar
Useful for sequential ribbons of sections. Available with or without a middle cross bar.
Folding / Double grids
Sometimes known as Oyster or sandwich grids. These are useful for materials and large particles that do not adhere to a flat grid surface and need to be sandwiched between two grid meshes.
Aperture / Hole grids
Aperture or hole grids as they are sometimes known come with a range of single hole sizes.
Grid storage
Grid boxes keep grids protected both for routine handling and storage. Their ease of use makes them ideal for handling and viewing grids and the high packing density and compact flat shape make them well suited to long term storage.
