Product Description

These thin cast films of Formvar have been strengthened with the addition of a layer of evaporated carbon on copper grids. The composite films have extra resilience and strength compared with carbon films. They are recommended for use where the grid has to undergo several processing steps during specimen preparation.

Supplied either in packs of 25 or 50 grids in a grid box depending on each particular product.

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



Optimal Support for Electron Microscopy

These copper H7 grids, coated with Formvar and an ultra-thin carbon film, provide a stable and continuous support for delicate specimens, crucial for high-contrast TEM imaging. Their 200-mesh hexagonal pattern ensures uniformity and consistent sample preparation, while the smooth, low background surface enhances imaging clarity for both biological and material samples.


Easy Handling and Long-Term Storage

Each grid is securely packed in a foam-lined storage box, minimizing the risk of damage or contamination. With a minimum shelf life of 2 years when stored cool and dry, and straightforward handling using antistatic tweezers, these grids are engineered for laboratory convenience and durability, making them reliable consumables for microscopy workflows.

FAQs of Formvar/Carbon Films on Copper H7 Grids (Pk 50):


Q: How should Formvar/Carbon Films on Copper H7 Grids be handled and stored?

A: Handle the grids using antistatic tweezers to prevent contamination or damage, and avoid direct contact with moisture. For best results and shelf life, store the grids in a cool, dry place within their original foam-lined grid storage box.

Q: What are the main benefits of using these grids for electron microscopy?

A: The grids provide a continuous, smooth support with a low background, enhancing image clarity and contrast in TEM for both biological and material specimens. The high-purity copper and quality films minimize interference, ensuring reliable and reproducible sample analysis.

Q: When are these grids commonly used in laboratory work?

A: These grids are routinely used during the sample preparation stage of transmission electron microscopy (TEM) for supporting ultrathin specimens, especially where both structural integrity and minimal background are essential.

Q: What types of specimens are compatible with Formvar/Carbon H7 Copper Grids?

A: These grids are suitable for a wide range of biological and materials science specimens, including tissue sections, nanoparticles, and thin filmsmaking them versatile supports in electron microscopy research.

Q: What process is involved in applying samples to these grids for TEM analysis?

A: Typically, a small volume of the specimen solution is deposited onto the film surface of the grid. Excess liquid is gently blotted away, and the grid is dried prior to inserting into the electron microscope for imaging.

Q: Where are these grids manufactured and distributed?

A: Formvar/Carbon Films on Copper H7 Grids are available from leading laboratory suppliers, exporters, manufacturers, and dealers in the United Kingdom and globally, ensuring high-quality standards for research professionals.
