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 Conductivity and Surface Quality

The combination of golds inherent conductivity and the uniformity of the carbon film ensures exceptional electron transport and specimen support. This makes these grids especially suitable for high-resolution TEM imaging and analytical techniques requiring low background noise and minimal contamination.


Versatility Across Research Applications

Carbon-coated gold grids are compatible with standard TEM holders and cartridges, making them highly versatile for various scientific investigations. Their inert nature and durability under electron beams make them indispensable in materials science, life sciences, and nanotechnology research.


Safe Handling and Longevity

Engineered for stability, these grids must be handled carefully using anti-static tools due to their delicate structure. Proper storage in dry, clean conditions extends their shelf life and maintains their high performance, ensuring consistent analytical results over time.

FAQs of Carbon films on Gold Grids:


Q: How should carbon films on gold grids be handled to maintain their integrity?

A: These grids are delicate and should be handled using anti-static tweezers or tools in a clean, controlled environment. Avoid direct contact with fingers to prevent contamination and potential damage to the ultra-thin carbon film.

Q: What is the typical application of carbon-coated gold grids in research?

A: They serve as specimen supports for Transmission Electron Microscopy (TEM), facilitating high-resolution imaging in materials science, nanotechnology, and biological studies due to their high conductivity and clean, stable surfaces.

Q: When should I opt for ultrathin carbon film variants?

A: Ultrathin carbon films are recommended for applications requiring greater electron transparency, such as imaging very fine structures or maximizing resolution in TEM studies. The choice depends on sample requirements and desired imaging outcomes.

Q: Where are carbon-on-gold grids typically used?

A: These grids are found in academic, industrial, and research laboratories worldwide, particularly those specializing in electron microscopy and advanced nanomaterials characterization.

Q: What are the benefits of using gold grids over copper or nickel alternatives?

A: Gold grids offer superior electrical conductivity, chemical inertness, and minimal oxidation over time, resulting in cleaner backgrounds and more reliable TEM imaging compared to copper or nickel grids.

Q: How long can these grids be stored and under what conditions?

A: Gold grids with carbon films are stable for extended periods when stored in dry, dust-free, and clean conditions. Proper storage prevents contamination and preserves both the carbon film and golds characteristics.

Q: What makes these grids suitable for analytical and high-precision work?

A: Their high purity, uniform carbon coating, and conformity to international standards make them reliable for analytical grade applications, providing reproducible and accurate results in demanding research environments.
