Product Description

Formvar coated grids without a carbon layer are suitable for TEM applications up to 100kV. The films are available on grids made of copper, nickel or gold.

Supplied as 25 grids in a grid box.

Gold

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

High-Performance Support for TEM Imaging

Formvar-coated F1 Finder Au Grids provide a dependable foundation for specimen preparation in TEM analysis. Their defect-free, smooth surface and high purity gold structure enhance image clarity and stability, enabling accurate results and reproducible data. The finder pattern further ensures precise specimen localization during investigations.

Optimized for Low Background and High Stability

The combination of gold grids and ultra-thin Formvar film delivers low background interference and robust support for samples under electron microscopy. The grids transparency and conductive properties facilitate sharp, high-fidelity images while protecting delicate specimens throughout the imaging process.

Secure Handling and Prolonged Preservation

Each grid is packaged in anti-static, closed containers for protection against dust, moisture, and static discharge. For best results and longevity, operators should handle grids using anti-static forceps and store them in dry environments, ensuring a shelf life exceeding 2 years.

FAQs of Formvar on 3mm F1 Finder Au Grids (Pack of 25):

Q: How should Formvar on 3mm F1 Finder Au Grids be handled to prevent damage?

A: Use anti-static forceps when handling the grids and avoid contact with moisture or dust. Grids should remain in their anti-static containers until ready for use to maintain integrity and prevent contamination.

Q: What is the main advantage of using the F1 Finder Au Grids with Formvar film for TEM?

A: These grids offer a smooth, defect-free Formvar support film on high purity gold, creating a low background and stable platform for imaging. The finder pattern improves specimen localization, supporting reproducible and precise TEM analysis.

Q: When is it recommended to use these grids for specimen preparation?

A: Formvar on 3mm F1 Finder Au Grids are ideal when conducting low-background, high-resolution electron microscopy that requires specimen stability and accurate location referencing, particularly in analytical and research laboratories.

Q: Where should these grids be stored to maintain their quality and prolong shelf life?

A: Store grids in a dry, dust-free environment within their original anti-static, sealed containers to protect against moisture, static, and airborne particulates. Proper storage can extend shelf life beyond two years.

Q: What process is followed for preparing the grid before placing specimens?

A: Ensure the grid is clean and free from dust, remove from the container with anti-static forceps, and place on a clean flat surface. Mount the sample gently onto the Formvar film, following standard TEM specimen preparation techniques.

Q: What benefits do Formvar-coated Finder Au Grids provide compared to conventional grids?

A: They offer high stability, excellent conductivity, minimal imaging background, and accurate specimen location. The transparent Formvar film also ensures unobstructed electron passage, enhancing imaging detail and resolution during TEM investigations.

Q: Can these grids be used with solvents or chemicals during sample processing?

A: Formvar is insoluble in water but soluble in aromatic and chlorinated hydrocarbons. For solvent-based sample processing, avoid solvents that dissolve Formvar to maintain film integrity during specimen application.
