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.

Unparalleled Imaging Performance

The gold H7 grids coated with Formvar and carbon offer exceptional stability, electron transparency, and uniformity, which are crucial for achieving optimal transmission electron microscopy (TEM) imaging. The combined layers enhance specimen support and reduce background noise, making them suitable for both delicate biological samples and robust material sciences investigations.

Precision Crafted for Laboratory Efficiency

Pre-mounted with support films and supplied in packs of 25, these grids save valuable preparation time and minimize waste. The smooth, conductive carbon surface promotes excellent sample adhesion, reducing artifacts and enabling reliable results in analytical workflows. Custom thickness and grid specifications are also available on request for specialized requirements.

FAQs of Formvar/Carbon Films on H7 Gold Grids (Pack of 25):

Q: How should Formvar/Carbon Films on H7 Gold Grids be handled during TEM specimen preparation?

A: For best results, handle the grids using clean gloves and anti-static tweezers. This prevents contamination and accidental static discharge, which can damage the ultrathin films and affect imaging quality.

Q: What types of samples and microscopy applications are suitable for these gold grids?

A: These grids are designed for various biological and material science samples in transmission electron microscopy (TEM). Their high electron transparency and smooth surface benefit imaging of cells, proteins, nanoparticles, and other fine structures.

Q: When is it necessary to request custom film thickness or grid type for specialized applications?

A: Custom film thickness or alternative grid configurations may be requested when your research requires unique electron transparency, support strength, or mesh size, beyond the standard H7 hexagonal mesh and film thickness provided in this pack.

Q: Where should the gold grids be stored to ensure optimal longevity and performance?

A: Store the grids in a dry, dust-free container at ambient room temperature, avoiding humidity and electrostatic environments. Proper storage ensures a shelf life of at least one year without compromising film quality or grid integrity.

Q: What are the main benefits of using gold (Au) grids over alternative metal supports for TEM?

A: Gold grids provide superior chemical resistance, high purity (99.99% Au), and stability, minimizing interference with sensitive samples. The high conductivity further assists in dissipating charge during electron microscopy, contributing to clearer images.

Q: How does the Formvar/Carbon film coating enhance the usability of these grids?

A: The dual-film structure improves sample adhesion, minimizes contaminants, and offers high electron transparency for detailed imaging. The carbon layer increases conductivity while the Formvar adds mechanical stability and uniformity.
