Consumables for transmission electron microscopy

Transmission electron microscopy (TEM) is a high-resolution microscope that uses a transmitted electron beam to pass through the sample and collects the interacting signals to generate micrographs. Consumables for transmission electron microscopy include the following components:

1.      TEM grids (Transmission Electron Microscope Grids): Grids are thin films used to support and hold samples. In TEM, grids are typically made of metal (such as copper or molybdenum) or carbon materials. They have tiny apertures to support the sample and allow the electron beam to pass through.

2.     Film: Film is a material used to prepare the grids for TEM. Films can be carbon films, metal films (such as copper films), etc. They usually exhibit good electron transmittance and provide stable support during observation.

3.     Carbon film supports: Carbon film supports are a specific type of TEM grid that is used to fix and support samples. They are typically made of carbon films and offer stable support and conductivity.

4.     TEM grid holders: TEM grid holders are devices used to hold and carry TEM grids. They are usually made of metal and can securely hold the grids on the specimen stage of the TEM, ensuring stable and accurate positioning of the sample inside the microscope.

5.     Specimen holders: Specimen holders are devices used to contain the samples and can be placed on the specimen stage of the TEM. They are typically made of metal and have suitable apertures and sizes to accommodate TEM grids and maintain sample stability.

These consumables play a crucial role in the sample preparation and observation processes of TEM, ensuring sample stability, conductivity, and observability. When using TEM, it is important to select the appropriate consumables based on requirements and follow the relevant operating guidelines and safety regulations.
