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 Support for Electron Microscopy

Designed for optimum sample support in Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM), these carbon films on copper grids feature a smooth surface, remarkable transparency, and low background. Their high purity, uniform thickness, and secure packaging ensure reliable, reproducible results for research and diagnostics.

Superior Material Properties

Combining ultrathin carbon films (1030 nm) with robust copper grids (3.05 mm diameter, 2030 m thick), these supports offer >99.5% purity, excellent electrical conductivity, and outstanding compatibility with most electron microscopes. They withstand temperatures up to 350C in vacuum, remaining stable and free from significant contamination, as required for EM work.

FAQs of Carbon films on Copper Grids:

Q: How should I handle and store carbon films on copper grids?

A: Handle these grids with clean, fine-tipped tweezers to avoid damage. Store them in a dry, clean environment, ideally in their original individually packed grid boxes to prevent physical damage and contamination.

Q: What are the main applications of carbon-coated copper grids?

A: Carbon films on copper grids are widely used as sample supports in Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM). They are indispensable for high-resolution imaging, analysis of nanoparticles, biological specimens, and many advanced materials.

Q: When is it beneficial to use an ultrathin (1030 nm) carbon film on a copper grid?

A: Ultrathin carbon films are ideal when high electron transparency and minimal background interference are required, such as in detailed imaging of low-contrast or sensitive samples during EM studies.

Q: Where are these grids compatible in terms of equipment?

A: These carbon-coated copper grids (3.05 mm diameter) are compatible with most standard TEM and SEM holders, making them suitable for laboratories worldwide that conform to typical electron microscopy sample specifications.

Q: What makes these carbon films on copper grids advantageous for EM work?

A: Their high electrical conductivity, low contamination levels, remarkable transparency, and smooth surfaces support high-quality, low-noise imaging. Additionally, their stable structure under vacuum and at elevated temperatures ensures reliability in demanding microscopy applications.

Q: What process is used to apply the carbon film onto copper grids?

A: The ultrathin carbon film is typically deposited onto copper grids by vacuum evaporation or similar vapor deposition techniques. This produces a uniform, smooth film that meets research-grade microscopy requirements.
