Product Description

Carbon films on gold grids are thin and highly transparent to electrons, offering fine grain and low contrast that does not interfere with specimen structure.

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.

Precision and Purity for TEM Applications

Every grid is fabricated using high-purity gold and amorphous carbon, ensuring optimal conductivity and stability under electron beams. The grids are meticulously coated to deliver even film thickness, maintaining transparency and minimizing background signals during imaging. Their ultrathin carbon film offers an ideal balance between strength and electron transparency for demanding microscopy work.

Long-Term Storage and Consistent Quality

Our gold carbon grids are packed in an inert atmosphere and supplied in secure storage boxes. This method safeguards them from contamination and physical damage, supporting their stability and performance for years if stored in a clean, dry environment. Each lot is traceable by batch-specific identifiers, ensuring consistent quality for reproducible scientific results.

FAQs of Carbon films on Gold Grids:

Q: How are carbon films on gold grids used in transmission electron microscopy (TEM)?

A: Carbon-coated gold grids act as specimen supports in TEM. Researchers apply samples onto the ultrathin, electron-transparent carbon film, which is mounted on a gold mesh grid. This setup stabilizes the specimen and provides a conductive, low-background support for high-resolution imaging.

Q: What are the main benefits of using gold grids with ultrathin carbon films?

A: These grids offer exceptional chemical inertness, superb electrical conductivity, and a smooth, non-reactive surface. The gold mesh enhances stability and reduces contamination, while the thin carbon film ensures superior imaging quality for sensitive samples in TEM.

Q: When should carbon films on gold grids be handled to maintain integrity?

A: Always wear gloves and avoid direct contact with the film when handling these grids. Use clean tweezers in a dust-free environment to prevent contamination and physical damage, preserving the grids electron-transparent properties.

Q: Where are carbon-coated gold TEM grids typically applied?

A: These TEM grids are widely used in research laboratories, universities, and industrial facilities for high-resolution electron microscopy. Applications include structural biology, materials science, and nanotechnology research.

Q: What is the standard process for storing and preserving the quality of these TEM grids?

A: Store the grids in their supplied, inert-atmosphere storage boxes in a clean, dry environment, away from moisture and dust. Proper storage ensures the carbon film remains stable and uncontaminated for years.

Q: What mesh sizes and film thickness options are available for these grids?

A: The gold grids are typically available in 200, 300, or 400 mesh sizes to cater to various sampling needs. The amorphous carbon film is generally supplied at a thickness between 1020 nm, ensuring optimal transparency and support.
