Product Description

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

Carbon Coating is 28-30nm

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.

Exceptional Transparency and Durability

These carbon-coated copper grids offer high electron transparency, crucial for high-resolution imaging in electron microscopy. The carbon film, reinforced by a sturdy copper grid, minimizes the risk of film breakage during handling, ensuring reliable support even during rigorous sample preparation and imaging sessions. Their excellent surface quality and structural integrity make them reliable for repeatable laboratory analyses.

Versatile Research and Analytical Applications

Primarily designed for TEM and SEM, these grids are indispensable for sample mounting in a variety of life science and materials research fields. Their compatibility with most electron microscope holders and analytical procedures means they fit seamlessly into established laboratory workflows. Theyre research/analytical grade and comply with EM laboratory standards, providing robust support for reliable, high-resolution data acquisition.

FAQs of Carbon films on Copper Grids:

Q: How should carbon films on copper grids be cleaned before use?

A: It is recommended to clean the carbon films on copper grids using plasma cleaning before sample deposition. This process enhances the hydrophilicity of the carbon surface and removes superficial contaminants, ensuring optimal imaging results.

Q: What are the benefits of using carbon films on copper grids in electron microscopy?

A: The combination of high electron transparency, excellent conductivity, and enhanced mechanical strength provides a stable and clear platform for imaging. This allows for improved sample contrast and minimizes charging effects during TEM or SEM analysis.

Q: When is it necessary to replace a carbon-coated copper grid?

A: Grids should be replaced if the carbon film shows visible tears, excessive contamination, or structural deformation. With proper handling and storage, these grids have a long shelf life, but usage frequency and sample type may influence when replacement is needed.

Q: Where should I store carbon films on copper grids to maximize shelf life?

A: Store the grids in a dry, dust-free environment, preferably in their original grid boxes or containers. Maintaining these conditions is essential to preserve surface quality and prevent contamination.

Q: What is the process of manufacturing carbon film on copper grids?

A: Carbon films are typically created by evaporating carbon onto clean copper grids in a vacuum chamber, followed by careful packing under dust-free conditions. This produces a thin (~2030 nm), even film that adheres strongly to the copper support.

Q: How are these grids compatible with electron microscope holders?

A: The grids have a standard diameter of 3.05 mm and circular shape, making them suitable for most electron microscope holders. Their precise manufacturing ensures a consistent fit across different instruments used in analytical and research laboratories.
