Transmission electron microscope (TEM) observes microscopic materials through the interaction of materials and electron beams. The resolution of TEM is thousands of times higher than that of optical microscope. TEM is an important analysis method in many related scientific fields such as physics and biology, cancer research, virology, materials science, nanotechnology and semiconductor research. The TEM grid is filled with tiny holes that support the sample and allow the electron beam to pass through unimpeded. The graphene suspended on the TEM grid prevents particles from sliding out of the holes, while allowing the electron beam to pass through and interact with the sample without any interference.
Alfa Chemistry provides graphene TEM grids and TEM support films that are suitable for excellent imaging and at an affordable price.
