Product Description

Lacey carbon films are similar to the holey carbon films in that they have open areas but because of the fine lacey mesh structure they offer a greater percentage of open area in comparison (see micrograph). They provide the thinnest possible support film while maintaining adequate strength and give practically no background interference in the TEM. As much of the specimen is unsupported, these films are appropriate for use where a structure free background is of importance. Lacey carbon films are particularly suitable for studying some nanotubes, acicular crystals and biological/materials specimens.

Supplied as 25 or 50 grids in a grid box.

Lacey carbon support films can be applied to other grid sizes, material or type. Further details available on request.



Exceptional Specimen Support and Visibility

The unique lacey carbon film pattern creates an optimal support surface for TEM specimens, minimizing background contrast and allowing greater visibility of nano-scale features. The 400 mesh copper grid structure is stable and smooth, preventing edge damage during handling and ensuring reliable imaging in particle analysis and nanomaterial studies.


Quality Materials and Safe Handling

Each grid is manufactured from high-purity copper, topped with amorphous carbon, and inspected for consistency and smoothness. The film supports ultra-thin samples without introducing contaminants. Grids should always be handled with tweezers, and direct contact with the film surface should be avoided to preserve integrity. Packaging in grid boxes prevents accidental contamination or damage.


Compatibility and Versatility in Research

Lacey carbon grids are compatible with the majority of standard TEM holders and suitable for diverse applications, from biological macromolecule imaging to advanced materials science. Their resistance to chemicals and extreme temperatures makes them ideal for demanding electron microscopy workflows where precision and clarity are essential.

FAQs of Lacey Carbon Films on 400 Mesh Copper Grids (Pack of 50):


Q: How should I properly handle Lacey Carbon Films on copper grids during specimen preparation?

A: Always use non-magnetic tweezers to pick up and transfer the grids. Avoid touching the lacey carbon film directly to prevent damage or contamination. Hold grids by the edge, not the surface, and work in a clean, dust-free environment whenever possible.

Q: What are the benefits of using a lacey carbon film compared to standard continuous film?

A: Lacey carbon films provide an irregular, web-like support that allows for maximum specimen visibility and minimal background interference in TEM images. This structure is particularly advantageous for studying nanoparticles, aggregates, or delicate specimens that might obscure data on denser supports.

Q: When should I choose a 400 mesh grid for my TEM application?

A: A 400 mesh grid offers a fine balance between support structure and open area. Its suitable for high-resolution imaging of small particles or nano-scale materials, providing enough support while maximizing specimen transmission for TEM analysis.

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

A: Store your grids at room temperature, protected within their original polystyrene grid box, and away from dust or environmental contaminants. Under these conditions, the grids exhibit an indefinite shelf life.

Q: What process is used to prepare samples on lacey carbon grids?

A: Typically, a small droplet of your specimen solution is placed on the grid and allowed to air dry, ensuring particles adhere to the carbon film. After drying, excess solution can be wicked away gently, and the grid can then be transferred to the TEM holder for imaging.

Q: What advantages do these grids offer for nanomaterial research?

A: Their high-purity carbon support and excellent electron transparency help deliver crisp, detailed images of nano-objects. The lacey pattern minimizes the background, making it ideal for particle dispersion studies, aggregate analysis, and other fine-structure characterizations.
