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.



Ultra-Clean, High-Purity Nickel Mesh

These grids are manufactured using nickel of greater than 99.9% purity, providing robust electrical conductivity and minimal background signal. The ultra-clean, pre-treated surfaces enhance hydrophilicity, allowing superior sample adherence and improved imaging results. Each grid is circular, 3 mm in diameter, and features square mesh openings, ensuring uniform support for electron microscopy specimens.


Pre-Coated Formvar Film for Optimal Support

Each nickel grid is coated with a single-sided Formvar support film with a thickness of 1030 nm. Formvar (polyvinyl formal) offers stable mechanical support and is chemically inert, suitable for handling ultra-thin sections or particle suspensions. This support is ideal for transmission electron microscopy (TEM), electron diffraction, and related particle analysis due to its consistent film quality and minimal contamination.


Secure Packaging and Long-Term Stability

Grids are individually stored in protective boxes to prevent contamination and mechanical damage. With proper storage in dry, dust-free containers at room temperature, these grids remain stable and ready for use for several years. Their solid, odorless Formvar-coated structure meets international TEM grid standards and ensures safe handling and transport for research applications.

FAQs of Formvar on 3mm 100 Mesh Ni Grids (Pack of 25):


Q: How should Formvar on 3mm 100 Mesh Nickel Grids be handled during specimen preparation?

A: Use forceps to handle these grids at all times, and avoid touching the Formvar film directly with your fingers. The ultra-thin film is sensitive to oils and moisture, which may compromise imaging quality. Store unused grids in their original protective boxes to maintain cleanliness.

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

A: These grids provide a combination of high-purity nickel for conductivity and a stable Formvar layer for mechanical support. The hydrophilic, ultra-clean finish enhances sample adherence, resulting in clearer TEM images, while the consistent mesh size supports uniform sample distribution.

Q: Where can these grids be used, and for what applications?

A: Formvar-coated nickel grids are suitable for use in transmission electron microscopy (TEM), electron diffraction, and particle analysis. They are ideal for preparing specimens from biological, materials science, and nanotechnology research in laboratory settings across the United Kingdom and globally.

Q: When is it appropriate to replace the grids or the Formvar film?

A: You should replace grids if the Formvar film is visibly damaged, torn, or contaminated, or if structural integrity is compromised during handling or imaging. Under proper storage conditions, unused grids are stable for several years, making regular replacement unnecessary unless compromised.

Q: What process is involved in specimen preparation using these grids?

A: Specimens are placed onto the Formvar film using micropipettes or grids are dipped in particle suspensions. The hydrophilic film facilitates even distribution. Once specimens are secured and dried, grids are loaded into the TEM for imaging and analysis.

Q: Is there any chemical reactivity or toxicity associated with these grids?

A: The nickel grid with Formvar film is non-toxic under normal laboratory conditions, and both components are chemically stable. The Formvar film is insoluble in water but can be dissolved in organic solvents like chloroform or acetone when required for specific analytical techniques.
