Product Description

Holey carbon films have many uses in microscopy but for certain applications the mesh sizes of standard TEM grids are too large to support the sample. Continuous carbon films can also be a problem due to the fact that the thin film can inelastically scatter electrons and contribute to background noise. Holey carbon films therefore are a suitable alternative.
Holey carbon films have holes of various sizes up to 100m. In addition to providing support, the increased image contrast in the regions of the holes compared to regions of film is also of benefit. Typical applications include biological and materials science and cryo-TEM.

Supplied as 25 or 50 grids in a grid box.
Holey carbon support films can be applied to other grid sizes, material or type. Further details available on request.

Ultra-Clean Imaging Support for TEM

These Holey Carbon Films are meticulously manufactured to guarantee ultra-clean surfaces, optimizing sample support for high-resolution imaging. The perforated carbon layer allows excellent electron passage, critical for analytical results in research and commercial microscopy environments. Leveraging golds conductivity, the grids reduce charging effects and enhance overall imaging quality.

Robust Grid Structure and Electron Transparency

Their pure gold mesh, with a grid diameter of 3.05 mm and nominal film thickness of 2030 nm, ensures high mechanical stability while maintaining outstanding electron transparency. The evenly distributed 15 micron holes permit effective sample visualization and structural integrity, making these grids a dependable choice for precise microscopy specimen mounting.

Versatile Compatibility and Ready-to-Use Convenience

Pre-cleaned and packaged in sets of 25, these grids arrive ready for immediate laboratory use. Their standard sizing and insolubility provide seamless compatibility with most TEM holders and mounting processes. Storage is simplejust keep them in a clean, dry container under ambient conditions for lasting performance.

FAQs of Holey Carbon Films on 200 Mesh Gold (Pack of 25):

Q: How do Holey Carbon Films on 200 Mesh Gold grids benefit TEM specimen preparation?

A: These grids provide a stable, ultra-clean support with high electron transparency and conductivity, enabling clearer imaging and accurate data acquisition for transmission electron microscopy (TEM) analyses.

Q: What is the process for mounting samples onto these grids?

A: Samples are typically deposited onto the perforated carbon film surface, which has holes sized for optimal electron passage. The ultra-clean, ready-to-use grids can be placed directly into TEM holders for further analysis without additional preparation.

Q: When should these grids be used in laboratory workflows?

A: These grids are designed for research-grade TEM sample preparation, particularly when high-resolution imaging and minimal contamination are required. They are suitable at any stage where reliable support film is essential for precise sample mounting.

Q: Where can these grids be stored to maintain their quality?

A: Store the grids in a clean, dry container under ambient conditions to preserve their ultra-clean surface and prevent contamination, ensuring optimal performance during TEM analyses.

Q: What types of specimens are compatible with these grids?

A: The grids are compatible with a wide variety of biological, chemical, or material science specimens, as the holey carbon film and gold mesh support diverse sample types while maintaining structural integrity and specimen visibility.

Q: How do these grids ensure high-resolution imaging for TEM?

A: The combination of an ultra-clean, thin holey carbon film and pure gold mesh maximizes electron transparency and conductivity, greatly reducing charging effects and providing an ideal substrate for high-resolution electron microscopy.

Q: What is the main benefit of using a pure gold mesh in these support films?

A: The pure gold mesh offers high electrical conductivity and mechanical stability, reducing background interference and enhancing image quality during TEM investigations.
