Product Description

These thin cast films of Formvar have been strengthened with the addition of a layer of evaporated carbon on nickel grids. The composite films have extra resilience and strength compared with carbon films. They are recommended for use where the grid has to undergo several processing steps during specimen preparation.

Supplied as 25 or 50 grids in a grid box.

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

Optimal Support for TEM Imaging

The continuous Formvar and carbon films provide a robust yet delicate substrate for mounting ultrathin samples. Their low background and uniform surface promote superior contrast and resolution, crucial for imaging intricate biological or material structures.

Reliable Packaging and Storage

Every pack of Formvar/Carbon on Nickel grids is supplied in a secure grid box, ensuring minimal handling damage and contamination. For optimal longevity, store in a dry environment, away from dust and humidity, maintaining their electron microscopy grade quality.

Broad Application and Compatibility

These grids are compatible with most standard TEM holders, supporting a wide range of biological and materials research applications. Their versatility and stability make them essential for academic labs, research centers, and industrial microscopy workflows.

FAQs of Formvar/Carbon on 75 Mesh Nickel (Pack of 25):

Q: How are Formvar/Carbon on Nickel TEM grids typically used?

A: These grids are primarily used as support films for ultrathin biological or material samples in transmission electron microscopy (TEM), allowing for high-resolution imaging with minimal background interference.

Q: What process is used to coat the carbon layer on these grids?

A: The carbon overlay is applied using a vacuum deposition method, ensuring a consistent, thin layer between 515nm thickness atop the Formvar film for enhanced imaging contrast and stability.

Q: When should I use 75 mesh Nickel grids with Formvar/Carbon films instead of other types?

A: Choose these grids when you need low-background, high-contrast TEM imaging for delicate or ultrathin samples, especially in high-resolution biological or material science applications where nickels strength and chemical stability are advantageous.

Q: Where are these grids manufactured and supplied from?

A: These laboratory-grade consumables are commonly manufactured, exported, and supplied by established dealers and producers in the United Kingdom, and are available through a variety of scientific suppliers and distributors.

Q: What are the benefits of using a Formvar/Carbon continuous film on nickel mesh?

A: This combination ensures both mechanical stability (from the nickel mesh) and minimal electron scattering (from the ultra-thin Formvar and carbon layers), delivering optimal support for clear, high-contrast TEM imaging.

Q: How should I store Formvar/Carbon on Nickel TEM grids for maximum shelf life?

A: Store the grids in their supplied grid box in a dry environment, avoiding humidity and contaminants, to preserve their electron microscopy quality for several years.

Q: What precautions should I take during handling and preparation?

A: Use clean tweezers and work in a low-contamination environment to avoid damaging the delicate film or introducing artifacts, ensuring the integrity of your TEM imaging results.
