Product Description

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

Carbon Coating is 28-30nm

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.

Uniform Ultra-Clean Surface for Optimal Imaging

Every carbon film on copper grid boasts a meticulously uniform and ultra-clean surface, providing reliable electron transparency essential for high-clarity imaging. The combination of amorphous or graphitic carbon film and high-purity copper ensures analytical accuracy for demanding research applications. Each grid undergoes strict quality control to minimize contaminants, allowing your samples to achieve error-free visualization in TEM and compatible adapted SEM workflows.

Highly Stable and Conductive Support Membrane

The carbon films are thoroughly engineered to deliver high electrical conductivity and robust thermal stability, tolerating temperatures up to 400C. The copper substrate offers excellent current flow, crucial for reducing charging effects in electron microscopy. The carbon membrane is neutral, non-toxic, and maintains its integrity during prolonged use, ensuring dependable performance throughout analytical and research experiments.

FAQs of Carbon films on Copper Grids:

Q: How are carbon films on copper grids used in electron microscopy?

A: These grids serve as support membranes for samples in transmission electron microscopy (TEM) or adapted scanning electron microscopy (SEM). Specimens are carefully deposited onto the carbon film, which offers an electron-transparent and ultra-clean platform, minimizing background signal for enhanced image clarity.

Q: What are the main benefits of using high-purity carbon film on copper grids?

A: The main benefits include low background interference, excellent optical transparency, and high thermal and electrical conductivity. This ensures precise high-resolution imaging, sample stability at elevated temperatures, and minimal distortion or signal loss during analysis.

Q: When should researchers use carbon films on copper grids?

A: Researchers should choose these grids when their work demands high-resolution TEM imaging, low signal noise, and stable, contamination-free sample preparationespecially in material science, biology, and nanoanalysis investigations.

Q: Where should these grids be stored for maximum shelf life?

A: For indefinite shelf life, store the grids at room temperature in a dry, moisture-protected environment. They are supplied in specialized storage boxes designed to prevent humidity or contaminant exposure.

Q: What is the process for preparing a sample on these grids?

A: To prepare a sample, deposit your material onto the carbon film surface using standard TEM sample methods. Allow any liquid carriers to evaporate fully. Handle grids carefully using non-metallic tweezers to avoid damaging the delicate carbon film.

Q: How does the copper grid mesh size affect applications?

A: Mesh size determines the density of the copper grids openings. Common mesh counts (200, 300, or 400) allow researchers to select the support best suited for their specimens size and the imaging resolution required.
