Product Description

Carbon films on gold grids are thin and highly transparent to electrons, offering fine grain and low contrast that does not interfere with specimen structure.

Supplied as packs of 25 or 50 grids in a grid box.

Carbon support films can be applied to other grid sizes, material or type. Further details available on request.



Superior Imaging Support for TEM Applications

These carbon films on gold grids are engineered for reliable performance in transmission electron microscopy (TEM). The combination of high-purity carbon and gold provides a sturdy yet ultra-thin support platform, ideal for imaging delicate biological or material science samples. With a customizable film thickness and optimal surface resistivity, these grids enhance image contrast while minimizing sample contamination.


Easy Handling and Long-Term Storage

Each grid is vacuum-sealed or packed in grid boxes to prevent exposure to contaminants. Designed for laboratory and analytical use, these carbon-coated gold grids are non-poisonous, odorless, and stable for indefinite periods when stored in dry, dust-free environments. Handle with fine forceps in clean conditions for best results.

FAQs of Carbon films on Gold Grids:


Q: How should I handle and store carbon films on gold grids to prevent contamination?

A: Always use fine forceps and handle the grids under clean conditions, such as a dust-free laminar flow hood. Grids should be stored in their vacuum-sealed containers or grid boxes to maintain cleanliness and prevent exposure to airborne particles.

Q: What applications are these carbon-coated gold grids best suited for?

A: These grids are primarily used as support films for transmission electron microscopy (TEM), aiding in the imaging of both biological and material samples at high resolution. Their robust design and conductive properties make them suitable for a variety of analytical and research uses.

Q: When should I consider customizing the carbon film thickness?

A: Customizing the film thickness (within the ~10-50 nm range) is recommended when your samples require specific support characteristicsthicker films provide more mechanical stability, while thinner films minimize background interference for improved image contrast.

Q: Where can these grids be used, and with which instruments are they compatible?

A: These carbon films on gold grids are compatible with most standard TEM holders and can be used in electron microscopy laboratories worldwide, including in research institutions, analytical labs, and industry settings.

Q: What is the process of manufacturing carbon films on gold grids?

A: Carbon films are carefully deposited onto gold mesh grids using evaporation or sputter-coating processes in controlled environments to achieve uniform thickness and high purity. The grids are then inspected, packaged, and vacuum-sealed for shipment.

Q: What are the main benefits of using a gold grid with a carbon support film?

A: The combination offers excellent electrical conductivity for reducing charging effects, high mechanical strength, and chemical inertness. Golds resistance to oxidation preserves grid integrity, while the carbon film provides a stable, continuous platform for sample support.

Q: Can the grids be reused after TEM analysis, and are they soluble in any solvents?

A: These grids are insoluble in water and most common solvents, but they are generally intended for single-use, as cleaning may damage the delicate carbon film. Reusing grids is not recommended unless the film remains intact and uncontaminated.
