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.

Nickel

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

Advanced Support Films for TEM Applications

These nickel grids are coated with Formvar, a polymer known for its mechanical strength and stability. The uniform, continuous film offers excellent support for electron microscopy sample preparations, minimizing background noise and enhancing imaging accuracy. Ideal for laboratories conducting research in nanotechnology, life sciences, and materials analysis.

Effortless Preparation and Reliable Performance

Formvar-coated nickel grids simplify the specimen mounting process due to their smooth, hole-free surface. The single-sided coating ensures consistent results and reduces specimen loss during handling. Their compatibility with transmission and select scanning electron microscopes makes them versatile consumables for various analytical needs.

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

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

A: Use fine tweezers to handle the grids, taking care not to touch the Formvar film directly. This preserves the integrity of the continuous, hole-free coating essential for accurate analysis.

Q: What are the primary benefits of using Formvar-coated nickel grids for TEM studies?

A: These grids provide a stable, smooth surface that improves imaging clarity, reduces background interference, and supports delicate specimens during transmission electron microscopy.

Q: Where should I store the Formvar-coated grids to maintain their quality?

A: Keep the grids in a designated grid box, protected from dust and humidity, at room temperature. Proper storage can extend shelf life up to two years.

Q: What is the process for dissolving the Formvar film if removal is required?

A: Formvar is insoluble in water but can be dissolved using organic solvents such as ethylene dichloride or chloroform, facilitating film removal when necessary for specific protocols.

Q: When are these grids suitable for use in electron microscopy?

A: They can be used whenever a reliable support film is required for sample preparation in laboratory, life sciences, or nanotechnology research, especially for TEM and certain SEM applications.

Q: What distinguishes these grids from uncoated alternatives?

A: The continuous, hole-free Formvar coating enhances sample stability and integrity, supports analytical/laboratory-grade standards, and minimizes contamination during imaging and analysis.
