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 Imaging Support for TEM

Carbon films on copper grids deliver smooth and highly electron-transparent support for TEM samples. Their uniform thickness and stability allow for precise imaging, making them the preferred choice in research laboratories for specimen preparation and analysis. The combination of inert carbon film and conductive copper grid ensures optimal conditions for high-resolution microscopy studies.

Reliable Structure and Composition

Manufactured using vacuum evaporation or arc deposition techniques, these support films offer high purity (over 99.9%) and consistent quality. Inspection through microscopy and thickness measurements ensures each grid meets stringent microscopy-grade standards. The carbon films inertness prevents sample interaction, while the copper grid provides excellent electrical conductivity for stable imaging.

Safe Handling and Long-Term Storage

Grids are packed in anti-static boxes and should be handled with tweezers to minimize contamination and physical damage. With an indefinite shelf life when stored properly in a clean, dry environment, users benefit from long-term reliability. The films are insoluble, odorless, and tasteless, maintaining stability and safety during microscopy workflows.

FAQs of Carbon films on Copper Grids:

Q: How should carbon-coated copper grids for TEM be handled to ensure sample integrity?

A: Use tweezers when handling the grids to avoid touching the film and risking contamination or mechanical damage. Always handle the grids in a clean area to maintain the films electron transparency and surface quality.

Q: What are the recommended storage conditions for these carbon films on copper grids?

A: Store the grids in their original anti-static grid boxes within a dry, contaminant-free environment. Proper storage prevents oxidation of the copper and preserves the carbon films smoothness and transparency, guaranteeing indefinite shelf life.

Q: When is it beneficial to choose different mesh sizes (200, 300, or 400)?

A: Mesh size selection depends on specimen type and desired imaging resolution. Lower mesh (200) offers larger openings for bigger samples, while higher mesh (300 or 400) provides finer support for smaller, delicate specimens during TEM analysis.

Q: Where are these carbon film on copper grids typically used?

A: They are mainly used in research laboratories, universities, and industrial facilities as specimen supports in Transmission Electron Microscopy (TEM), enabling high-resolution analysis across biological, materials science, and nanotechnology applications.

Q: What process is used for depositing the carbon film onto the copper grid?

A: The carbon film is produced via vacuum evaporation or carbon arc deposition, ensuring high purity and uniform thickness. Subsequent quality control checks, including microscopy and thickness measurements, ensure reliable TEM performance.

Q: How does this product benefit TEM analysis?

A: The smooth, electron-transparent carbon film enhances imaging clarity by providing a stable substrate for specimens. Its inertness prevents interaction with samples, while the conductive copper grid supports efficient electron flow during microscopy.
