Product Description

Formvar coated grids without a carbon layer are suitable for TEM applications up to 100kV. The films are available on copper grids. Nickel and gold grids are also available.

Supplied as 25 grids in a grid box.

Superior Support for TEM Applications

These Formvar-coated copper finder grids are crafted for reliable specimen support in transmission electron microscopy. Their neutral pH, high electrical conductivity, and clean, oil-free surface make them ideal for high-resolution imaging of delicate EM samples. The F1 finder mesh pattern helps with precise sample localization and orientation during analysis.

High Purity and Excellent Transparency

With a high-grade copper mesh and ultra-thin Formvar film, these grids provide exceptional electron beam transmission while maintaining structural integrity. The transparent Formvar layer ensures minimal interference with imaging, enabling accurate observation of even fine specimen details under TEM.

Professional Quality and Reliable Packaging

Each pack contains 25 grids, individually prepared to meet EM laboratory standards. They are supplied clean, oil-free, and ready for immediate use. Storage in a dry, dust-free desiccator preserves grid quality, allowing for a shelf life of 1224 months. This guarantees consistent performance for professional laboratory workflows.

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

Q: How should I store Formvar on 3mm F1 Finder Cu Grids to maximize their shelf life?

A: To ensure optimal preservation, store these grids in a dust-free, dry desiccator. Proper storage conditions help maintain their high quality and extend shelf life to 1224 months.

Q: What is the benefit of the transparent Formvar film on these TEM grids?

A: The 1520 nm Formvar film provides excellent electron beam transmission, enhancing image clarity and minimizing sample interference. Its transparency makes it ideal for detailed electron microscopy analysis.

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

A: These support grids should be used during transmission electron microscopy sample preparation, especially when a clean, oil-free, and highly conductive surface is required for high-resolution imaging.

Q: Where can these Formvar on Cu grids be used?

A: These grids are compatible with most TEM holders and suited for a wide range of electron microscopy laboratories, including research facilities, professional EM labs, and universities in the United Kingdom and worldwide.

Q: What is the process for mounting specimens on these grids?

A: Specimens are typically placed onto the Formvar film, which acts as a support for TEM analysis. The clean and oil-free surface facilitates easy mounting and positioning of delicate samples.

Q: Can these grids be dissolved in water or common solvents?

A: The copper grid is insoluble, and the Formvar film does not dissolve in water but is soluble in organic solvents such as chloroform and ethylene dichloride, useful for selective film removal during advanced sample preparation.

Q: Why choose the F1 Finder pattern for electron microscopy work?

A: The F1 Finder mesh pattern simplifies specimen localization on the grid, allowing users to efficiently navigate and identify specific areas of interest during microscopic analysis.
