Lacey Carbon Films on 300 Mesh Copper Grids (Pack of 25) from G-Hexa is a premium transmission electron microscopy (TEM) support film designed for high-resolution imaging with minimal background interference. Featuring a fine, random lacey (spider-web-like) mesh structure, these films offer a significantly greater percentage of open area compared to standard holey carbon films, providing the thinnest possible support while ensuring structural strength and virtually no electron scattering or contrast from the film itself. Ideal for applications requiring structure-free backgrounds, they excel in supporting delicate or unsupported specimens, making them a top choice for advanced research in life sciences, materials science, nanotechnology, and semiconductors.

Specifications

Key Applications & Uses

• Nanomaterials & Nanotubes Research — Excellent for imaging carbon nanotubes, nanowires, acicular crystals, and other elongated nanostructures with minimal support interference.
• Biological Specimens — Ideal for cryo-TEM or ambient imaging of delicate biomolecules, viruses, proteins, or cellular components where a structure-free background is critical to avoid artifacts.
• Materials Science & Polymers — Supports high-resolution analysis of thin films, composites, polymers, and crystalline materials requiring large open areas for clear visualization.
• Semiconductor & Nanotechnology — Used for characterizing nanoparticles, quantum dots, graphene derivatives, or semiconductor nanostructures with reduced background noise.
• High-Resolution TEM Studies — Preferred when specimens need maximal unsupported regions for direct electron transmission, such as in single-particle analysis or ultrathin sections.
• Graphene & 2D Materials Support — Often serves as a base for additional ultrathin films (e.g., graphene overlays) in advanced hybrid supports.

Frequently Asked Questions (FAQs)

Q1: What makes Lacey Carbon Films different from standard holey or continuous carbon films? A: Lacey films feature a fine, random mesh (spider-web-like) structure with a much greater open area percentage than holey films, offering thinner support, greater specimen exposure, and virtually no background interference in TEM imaging.

Q2: Are these grids suitable for cryo-TEM applications? A: Yes — their high open area and minimal interference make them excellent for cryo-TEM, especially for biological samples or nanomaterials requiring unsupported regions in vitreous ice.

Q3: What is the typical hole size or open area in Lacey Carbon Films? A: The lacey structure provides a wide, irregular range of hole sizes (random mesh), maximizing open area compared to uniform holey films — ideal for specimens needing extensive unsupported regions.

Q4: Can these be used with other materials like graphene? A: Absolutely — Lacey carbon is commonly used as a robust base support for overlaying ultrathin graphene or other 2D films in advanced TEM setups.

Q5: What grid material and size are standard? A: 300 mesh copper grids (3.05 mm diameter) are standard for this pack; copper provides excellent conductivity and is widely compatible with most TEM holders.

Q6: How should these grids be handled and stored? A: Handle with fine forceps in a clean environment; store in the provided grid box under dry, dust-free conditions to prevent contamination or damage.

Q7: Are custom configurations available (e.g., different mesh or metal)? A: Yes — G-Hexa offers Lacey films on 200/400 mesh, nickel, gold grids, finder grids, or other specifications; contact us for details and quotes.

Q8: Is plasma cleaning or glow discharge recommended before use? A: Yes — for better hydrophilicity and sample adhesion (especially biological specimens), brief glow discharge or plasma treatment is often beneficial.

Q9: What is the pack quantity and packaging? A: Pack of 25 grids in a secure anti-static grid box; larger packs (e.g., 50) or custom quantities available as per lab requirements.

Q10: Who are these primarily designed for? A: Researchers, universities, pharma/biotech labs, materials science groups, and nanotechnology/semiconductor facilities requiring high-quality, low-interference TEM supports for precise nanoscale imaging.
