Product Description

Carbon films on nickel grids are thin and highly transparent to electrons, offering fine grain and low contrast that does not interfere with specimen structure.

Supplied as packs of 25 or 50 grids in a grid box.

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

Efficient Sample Support for TEM

Carbon films on nickel grids are renowned for delivering superior support to samples during Transmission Electron Microscopy. The continuous or lacey carbon film results in high electron transparency, providing optimal imaging quality for both biological and material specimens. The robust nickel base ensures structural integrity, allowing repeated high-temperature analysis without deformation.

Ultra-Thin Membrane for High Resolution

The ultra-thin carbon film, with thicknesses ranging from 10 to 30 nm, furnishes an exceptionally smooth and uniform surface ideal for capturing fine sample details at microscopic scales. This precise fabrication, combined with a metallic lattice substrate, enhances resolution and contrast during advanced microscopy and material science research.

Reliable Handling and Storage

To maximize longevity and performance, these grids are packaged securely in grid boxes or anti-static holders and should be handled only with fine tweezers. By avoiding direct film contact and storing in dry, dust-free conditions at room temperature, users ensure indefinite shelf life and optimal sample protection during research workflows.

FAQs of Carbon films on Nickel Grids:

Q: How should carbon films on nickel grids be handled to prevent damage?

A: Carbon films are extremely delicate and must be handled only with fine tweezers. Direct contact with the ultra-thin film should be avoided to prevent rupturing or contaminating the membrane, ensuring reliable support for microscopy samples.

Q: What types of samples are compatible with these carbon-coated nickel grids?

A: These grids are compatible with a wide variety of biological and material samples. Their inert, insoluble character makes them suitable for TEM imaging of cells, viruses, polymers, nanoparticles, and other specimen types under laboratory conditions.

Q: When is continuous versus lacey carbon film recommended for use?

A: Continuous carbon films are favored for uniform sample support and high-contrast imaging needs. Lacey films, with their irregular pattern, allow for studies involving larger particles, suspended specimens, or when samples benefit from areas without underlying film.

Q: Where and how should these grids be stored for best longevity?

A: Store the carbon film nickel grids in a clean, dry, dust-free environment at room temperature, preferably inside anti-static holders or grid boxes. This protects against contamination and mechanical damage, ensuring indefinite shelf life and optimal imaging characteristics.

Q: What benefits do carbon films on nickel grids offer for electron microscopy?

A: These films provide high electron transparency, stable performance at elevated TEM imaging temperatures, and a smooth, uniform surface. Such properties greatly improve imaging resolution, reliability, and sample integrity in advanced microscopy applications.

Q: What is the process of preparing these grids for sample application?

A: After removing the grid from its protective packaging with tweezers, samples are deposited onto the film. The grids are then ready for loading into TEM instruments, where the carbon film serves as an ultrastructural support compatible with biological and material specimens.

Q: How does the nickel substrate contribute to the grids functionality?

A: Nickel substrates offer excellent mechanical strength, chemical stability, and high purity (99.9%), supporting the fragile carbon film and maintaining grid shape during TEM analysis, even at elevated temperatures.
