Product Description

These are pure carbon films, with no Formvar backing, mounted on top of a supporting carbon lacey film. The thickness of the carbon support film lying over the holes is less than 3nm and is the thinnest carbon support film available. It is particularly useful for high resolution microscopy of low contrast particles and is also ideal for use with the Energy Filtering TEM.

400 mesh 3.05mm dia copper grid. Pack of 25.

Superior Electron Transparency

This ultra-thin carbon film ensures minimum beam scattering, making it optimal for high-resolution electron microscopy. The 3nm thickness provides exceptional clarity and detail in biological and materials science applications, while retaining a continuous, uniform surface for reproducible results.

Reliable Support and High Stability

Mounted on lacey carbon grids (copper or nickel), the film delivers both strength and flexibility. Its resistance to temperatures exceeding 1600C in inert environments, along with insolubility in water and most solvents, enhances durability for routine and extreme applications alike.

Optimized for Versatile Research Applications

Designed to meet electron microscopy laboratory standards, this support film is suitable for cryo-EM, nanoparticle imaging, membrane support, and other advanced research tasks. Customization options ensure you receive the ideal grid and mesh to suit your specific experimental requirements.

FAQs of Ultra-thin carbon support film, 3nm - on lacey carbon:

Q: How should I handle the ultra-thin carbon support film to avoid damage?

A: Due to its exceptional thinness and fragility, always handle the support film by holding the grid edge with precision tweezers and avoid any direct contact with the film area to prevent tears or contamination.

Q: What are the main benefits of using a 3nm ultra-thin carbon support film in TEM applications?

A: The 3nm film provides high electron transparency, allowing for optimal imaging contrast and resolution. Its continuous, ultra-flat surface improves reproducibility, and the supports high purity reduces background signal in electron microscopy.

Q: When is customization available for the grid substrate or mesh size?

A: Customization is available upon request for grid materials (copper or nickel), mesh sizes (typically 200, 300, or 400 mesh), and quantities, enabling adaptation to your projects specific needs.

Q: Where should the ultra-thin carbon support film be stored for maximum shelf life?

A: Store the product in a clean, dry, and dust-free environment to maintain its stability and shelf life, which can extend to several years under proper conditions.

Q: What process is used to manufacture the 3nm carbon film on lacey carbon?

A: The film is produced using physical vapor deposition (PVD), which deposits an ultra-thin amorphous carbon layer uniformly on a lacey carbon grid, creating a consistent and high-purity support.

Q: How does this support film withstand extreme temperatures or high-vacuum conditions?

A: The film is engineered to resist temperatures above 1600C in inert atmospheres and is ultra-high vacuum compatible, making it suitable for a range of demanding microscopy and materials science experiments.

Q: What typical use cases benefit from this ultra-thin carbon support film?

A: The film excels in applications such as biological and materials science TEM imaging, cryo-electron microscopy, and as a support for dispersing nanoparticles, where high-resolution imaging and minimal background interference are essential.
