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.

Superior Sample Support for TEM Applications

Carbon films on copper grids deliver outstanding mechanical and electrical properties, making them indispensable for accurate Transmission Electron Microscopy (TEM) work across materials science, nanotechnology, and life sciences. Their high purity and uniform surface finish boost sample integrity while minimizing background interference.

Optimal Mesh, Diameter, and Thickness for Consistency

Available in standard mesh sizes of 200, 300, or 400, with a grid diameter of 3.05 mm and copper thickness of 2025 m, these grids conform to internationally recognized specifications. The carbon films 1025 nm thickness assures repeatable and stable imaging results for even the most delicate specimens.

Unmatched Quality and Extended Shelf Life

Supplied in sealed boxes, carbon on copper grids retain their integrity indefinitely under recommended storage conditions. Their contamination-free handling and analytical-grade purity meet demanding international standards for TEM sample preparation.

FAQs of Carbon films on Copper Grids:

Q: How should carbon films on copper grids be stored to maintain their quality?

A: Store the grids in a dry environment, ideally within sealed, contamination-free dispensers or grid boxes, to preserve their indefinite shelf life and prevent sample degradation.

Q: What are the benefits of using copper grids with carbon film for TEM?

A: The grids offer a clean and uniform surface with excellent electrical conductivity, which ensures sample stability, reduces imaging background, and supports reliable data acquisition.

Q: When is the ideal time to use carbon films on copper grids in microscopy?

A: These support films are best employed during the sample mounting stage in electron microscopy, material science, nanotechnology, and life sciences to hold ultrathin specimens securely for high-resolution TEM analysis.

Q: Where can carbon films on copper grids be applied besides TEM?

A: In addition to Transmission Electron Microscopy, these grids are suited for various electron microscopy techniques, including sample support in material science research, nanotechnology studies, and biological specimen analysis.

Q: What is the process for preparing samples with these grids for TEM analysis?

A: Specimens are mounted on the carbon films, which provide a stable, conductive platform. The low background and clean surface allow for consistent imaging results and accurate interpretation.

Q: Why is the mesh size important in carbon films on copper grids?

A: Mesh size determines the support films open areas and specimen coverage. Common sizes (200, 300, and 400 mesh) accommodate different sample types and help optimize imaging conditions for varied analytical requirements.
