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.

Exceptional Imaging Support for TEM

Engineered with ultra-thin, high-purity carbon films on sturdy gold grids, our product ensures high electron transparency and exceptional support. This combination is ideal for precise, contamination-free imaging and sample preparation in TEM applications, providing consistent outcomes across a broad spectrum of specimen types.

Ready-to-Use and Simple Handling

Each grid is delivered pre-mounted in protective grid boxes, enabling immediate use upon arrival. Plasma cleaning guarantees cleanliness, while anti-static precautions during handling help preserve the integrity of these delicate films. Storing the grids in dry, particle-free environments promotes a long usable shelf life.

Rigorous Quality and Compliance

Manufactured to stringent electron microscopy standards, our grids are crafted from >99.9% pure elemental carbon and gold. Compliance with CAS and EINECS identifiers and consistent mesh uniformity ensure reliability for research, diagnostics, and industrial imaging applications.

FAQs of Carbon films on Gold Grids:

Q: How should I properly handle carbon films on gold grids?

A: Always use anti-static forceps when handling the grids, and avoid folding or bending the ultra-thin carbon films. Handle them in a dust-free environment to maintain their integrity and minimize contamination.

Q: What is the benefit of using gold grids over traditional copper grids?

A: Gold grids provide higher rigidity and chemical inertness compared to copper, reducing contamination and background signal while enhancing mechanical stability during TEM imaging.

Q: When are these grids ready for use after purchasing?

A: The carbon films on gold grids come pre-mounted and plasma cleaned in grid boxes, making them immediately ready for TEM sample preparation and imaging upon delivery.

Q: Where should I store these carbon-coated gold grids for maximum longevity?

A: Store the grids in a clean, dry, and dust-free environment. Proper handling and protected storage in supplied grid boxes will preserve their cleanliness and prolong shelf life.

Q: What process is used to ensure high surface cleanliness of the grids?

A: All grids undergo plasma cleaning prior to packing, effectively removing contaminants and ensuring a pristine surface suited for high-resolution electron microscopy.

Q: How are these grids used in electron microscopy?

A: These grids serve as a robust support for thin specimens during TEM imaging, providing excellent electron transparency and a stable platform for detailed structural analysis at the microscopic scale.

Q: What advantages do ultra-thin carbon films provide for TEM applications?

A: Ultra-thin carbon filmstypically between 1020 nm thickdeliver high electron beam transparency and minimal background signal, optimizing contrast and clarity for sensitive or low-contrast samples.
