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.

Superior Grid Support for TEM Applications

These grids offer excellent specimen support for TEM due to the combination of Formvar and carbon films on pure copper substrates. The smooth surface finish ensures reliable sample mounting and consistent results during negative staining or sectioning. Their high purity and robust construction help minimize artifacts and beam damage while maintaining clarity for high-resolution imaging.

Reliable Performance in Laboratory Settings

The 400-mesh configuration allows for optimal sample coverage and stability. Manufactured to meet electron microscopy preparation standards, these grids are suitable for a range of laboratory uses, from routine diagnostics to advanced research. Their insolubility in water and resistance to electron beams make them dependable for long-term projects.

Easy Handling and Storage Guidelines

Handle these grids using antistatic and clean-room techniques to preserve their integrity. Store in a clean, dry environment to prevent contamination and extend lifespan. With proper care, the grids remain stable and ready for immediate use, enhancing workflow in busy research or testing facilities.

FAQs of Formvar/Carbon on 400 Mesh Copper (Pack of 25):

Q: How should I handle Formvar/Carbon on 400 Mesh Copper grids to avoid contamination?

A: It is important to use antistatic tools and maintain clean-room procedures when manipulating these grids. This minimizes the risk of introducing dust, oils, or other contaminants that could affect sample integrity during TEM analysis.

Q: What is the benefit of combining Formvar and carbon films on copper grids?

A: The Formvar layer provides excellent mechanical support for specimen mounting, while the carbon coating adds excellent resistance to electron beam damage and enhances contrast for negative staining and sample sectioning in TEM.

Q: When are these pre-coated TEM grids typically used in research?

A: Researchers use these grids for specimen support, negative staining, and sample sectioning during TEM studies. Their robust coatings help ensure clear, reproducible results, especially in routine imaging and diagnostic settings.

Q: Where can these grids be used, and with which instruments are they compatible?

A: Formvar/Carbon on 400 Mesh Copper grids are compatible with most Transmission Electron Microscopes (TEM). They are suitable for laboratory, research, and diagnostic facilities across the United Kingdom.

Q: What storage conditions help maintain the quality and shelf life of these grids?

A: Store the grids in a clean, dry environment while avoiding direct contact with dust or solvents. Proper storage ensures their stability and usability whenever specimen preparation is necessary.

Q: How does using these grids support my TEM sample preparation process?

A: These grids simplify specimen mounting, provide a smooth and uniform support film, and minimize sample loss or damage during sectioning, all of which contribute to improved quality and efficiency throughout the TEM workflow.
