Product Description

These thin cast films of Formvar have been strengthened with the addition of a layer of evaporated carbon on nickel 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 as 25 or 50 grids in a grid box.

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



Reliable Support for Electron Microscopy

These Formvar/Carbon coated nickel grids provide strong, consistent support for specimens during transmission electron microscopy (TEM). The thin Formvar and carbon films minimize background interference while maintaining grid integrity, making them ideal for achieving high-quality imaging results in demanding laboratory environments.


High Purity, Electron Microscopy Grade Materials

Manufactured using >99.5% pure nickel mesh and high-quality carbon and Formvar, these grids conform to rigorous electron microscopy standards. Their excellent chemical purity and inert properties help prevent contamination, ensuring accurate and reproducible sample analysis for scientific and industrial applications.


Easy Compatibility and Handling

With a standardized 3.05 mm diameter and 200 mesh grid, these supports fit most specimen mounts and TEM holders used globally. Their robust construction ensures easy handling and reduces the risk of film breakage during sample mounting, storage, and transfer, streamlining laboratory workflows.

FAQs of Formvar/Carbon on 200 Mesh Nickel (Pack of 25):


Q: How do Formvar/Carbon on 200 Mesh Nickel grids benefit TEM specimen preparation?

A: These grids provide a stable, inert surface that improves specimen support and minimizes background noise, resulting in clearer images and more reliable data in transmission electron microscopy applications.

Q: What is the typical process for using these grids in TEM?

A: Specimens are deposited onto the coated side of the grid, and excess solution may be wicked away before drying. Once prepared, the grid is loaded into a TEM holder for imaging. The robust film helps maintain specimen integrity throughout the process.

Q: When should I select a nickel mesh over copper or gold grids?

A: Nickel meshes are chosen for their chemical resistance and suitability for samples that may interact with copper or gold. They are also preferable when using analytical techniques sensitive to other metals or where magnetic properties are required.

Q: What solvents can be used to remove the Formvar or carbon film if needed?

A: Formvar is soluble in trichloroethylene and similar organic solvents, while the carbon coating can be removed using certain organic solvents or by plasma cleaning, if desired, before specimen mounting.

Q: Where should I store unused Formvar/Carbon coated grids?

A: Store these grids in a dry, dust-free container at room temperature to maintain film integrity and prevent contamination. Proper storage ensures long shelf life and consistent performance.

Q: Are there any safety concerns when handling these grids?

A: The grids are non-poisonous for laboratory use but may cause allergic reactions in sensitive individuals due to the nickel mesh. Gloves and tools should be used to minimize direct skin contact and ensure safe handling.
