Exceptional Support for Electron Microscopy

These 3mm 400 Mesh Au Grids with Formvar film provide unmatched specimen support for TEM applications. The continuous, ultra-thin Formvar film ensures electron transparency and reliable sample adhesion, while the pure gold grid guarantees excellent conductivity and non-magnetic performance. Suitable for advanced imaging of biological and material samples, these grids are engineered for stability and consistency in demanding laboratory environments.


Easy Handling and Sample Preparation

Grids are supplied in a convenient pack of 25, making them ideal for high-throughput research and routine lab work. Handle with fine tweezers to avoid damaging the delicate Formvar film. Compatible with most negative staining procedures and TEM methodologies, these grids help streamline sample preparation for accurate imaging and analysis.

FAQs of Formvar on 3mm 400 Mesh Au Grids (Pack of 25):


Q: How should Formvar on 3mm 400 Mesh Au Grids be handled during preparation?

A: Handle these grids using fine tweezers and avoid touching the Formvar film directly, as it is thin and delicate. This prevents tearing or contamination, ensuring optimal specimen support for TEM imaging.

Q: What is the primary benefit of using pure gold grids with Formvar film in TEM?

A: Pure gold grids provide excellent electrical conductivity and non-magnetic properties, while the continuous Formvar film offers electron transparency and stable support for samples. This combination enhances imaging quality and reduces background noise in electron microscopy.

Q: When is it appropriate to use these grids in sample preparation?

A: These grids are suitable for most TEM sample preparations, including negative staining, biological specimen support, and materials science research. Use them whenever high structural and imaging precision is needed in transmission electron microscopy.

Q: Where should the grids be stored to maintain their properties?

A: Store the grids in a dry, dust-free environment at room temperature to maximize their shelf life (minimum two years) and maintain film integrity for laboratory use.

Q: What is the process for applying a specimen to the Formvar-coated grid?

A: Carefully place your sample onto the Formvar film, ensuring minimal pressure. The continuous, electron-transparent film will support the specimen for TEM imaging. Ensure compatibility with solvents used in your preparation protocol, as Formvar is soluble in certain organic solvents.

Q: How does the film coating affect grid performance in electron microscopy?

A: The single-sided Formvar layer acts as an insulating support that is highly electron-transparent, allowing for detailed imaging of thin specimens while preserving their morphology. It contributes to the stable positioning of samples during TEM analysis.
