Product Description

These thin cast films of Formvar have been strengthened with the addition of a layer of evaporated carbon on gold 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.

Exceptional Support for Electron Microscopy

Combining the superior conductivity and low background of a 99% pure carbon layer with the robust mechanical properties of Formvar, these films on gold grids ensure sharp imaging and minimal artifact interference during TEM. Suitable for particle analysis and ultra-fine structural studies, they are engineered for demanding research applications.

Quality and Durability You Can Trust

Each grid undergoes hydrophilic surface treatment, allowing for smooth dispersion and enhanced adherence of biological or particulate samples. The gold F1 mesh provides chemical inertness and mechanical strength, reducing contamination risks and enhancing grid longevity under repeated electron exposure.

Convenient Packaging and Reliable Shelf Life

Every pack includes 25 individually stored grids within anti-static, moisture-controlled grid boxes, ensuring preservation from oxidation, static, or contaminants. With proper storage at room temperature and dry conditions, these support films maintain their analytical integrity indefinitely.

FAQs of Formvar/Carbon Films on F1 Gold Grids (Pack of 25):

Q: How are Formvar/Carbon Films on F1 Gold Grids typically used in electron microscopy?

A: These grids are used as support films for Transmission Electron Microscopy (TEM), enabling the preparation and imaging of fine particles, biological specimens, and nanomaterials. The Formvar/Carbon coating provides mechanical stability while reducing electron beam interference, which is essential for high-resolution analyses.

Q: What are the main benefits of choosing gold mesh grids with Formvar/Carbon coatings?

A: Gold mesh provides superior chemical inertness and stability compared to copper, minimizing sample contamination. The Formvar/Carbon dual film offers excellent smoothness, hydrophilicity for easy sample spreading, and low background noise, vital for accurate imaging and analysis.

Q: When should I use Formvar/Carbon coated gold grids versus other support films?

A: These grids are ideal when superior stability, low contamination, and exceptional imaging clarity are needed. Applications include high-resolution particle analysis, biological sample imaging, and situations demanding inert, hydrophilic substrates compatible with the majority of TEM equipment.

Q: Where should I store these grids to maximize shelf life?

A: Store the grids in their original, moisture-controlled and anti-static packaging, in a dry environment at room temperature. Protecting them from excessive heat and humidity prevents degradation or contamination, ensuring indefinite shelf life.

Q: What is the process for preparing samples on these Formvar/Carbon gold grids?

A: Simply mount your specimen onto the hydrophilic, smooth surface of the grid. The films support adherence and spreading, making them suitable for negative staining, particle suspension, or thin section mounting prior to TEM analysis. Use tweezers to handle grids and avoid contact with solvents like chloroform, which dissolve the Formvar film.

Q: Are these grids compatible with all electron microscopes?

A: Yes, Formvar/Carbon Films on F1 Gold Grids (3.05 mm diameter) are compatible with most standard Transmission Electron Microscopes (TEM) and can be used interchangeably with instruments accepting standard grid holders.

Q: What should I do if the Formvar support film appears damaged or breaks?

A: If the Formvar film is ruptured, the grid should be discarded, as mechanical and imaging performance will be compromised. Handle grids carefully with clean, anti-static tweezers, and always keep them in their original box until ready for use.
