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.

Optimized for Electron Microscopy

Designed for high-performance imaging, these carbon-coated nickel grids serve as reliable supports in both transmission and scanning electron microscopy. Their superior conductivity and smooth carbon film facilitate clear sample visualization, especially for demanding high-resolution tasks.

Exceptional Usable Area and Durability

Supporting efficient sample placement, each grid features a large usable area (minimum 75% open) and is constructed from high-purity nickel. The carbon film is insoluble under normal laboratory conditions and withstands routine specimen preparation protocols without degradation.

Safe Handling and Versatile Packaging Options

Safe for general laboratory use, these grids are non-poisonousthough nickel may cause skin sensitization in rare cases. Grids come vacuum-sealed in vials of 25, 50, or 100, preserving their pristine state until needed for imaging.

FAQs of Carbon films on Nickel Grids:

Q: How should carbon films on nickel grids be stored for maximum stability?

A: To maintain stability and prevent contamination, store the grids in a clean, dry, and dust-free environment at room temperature. Keep them sealed in their original packaging until use.

Q: What advantages do these grids provide for TEM and STEM imaging?

A: Their ultra-thin, even carbon film ensures high electron transparency and conductivity, which are vital for high-resolution imaging and accurate specimen observation in both TEM and STEM applications.

Q: When is it necessary to hydrophilize the carbon film, and what method is recommended?

A: Hydrophilization is recommended just before sample deposition if enhanced wettability is required, typically for biological specimens. Glow discharge is the preferred method to render the carbon surface hydrophilic.

Q: Where are these microscopy grids commonly utilized?

A: These grids are widely used in research labs, academic institutions, and industrial facilities for supporting specimens in electron microscopy, especially in the United Kingdom and other regions adhering to EM-grade standards.

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

A: After optionally hydrophilizing the grid, place your specimen onto the carbon surface, allow it to dry if necessary, and proceed with your standard negative staining or embedding protocol before imaging.

Q: How does the high open area benefit users?

A: A large open mesh area (75%) maximizes the chances of finding unbroken, useable support for your sample, facilitating efficient screening and minimizing sample loss.

Q: What are the handling precautions and safety considerations?

A: These grids are non-poisonous; however, individuals sensitive to nickel may experience skin sensitization. Use tweezers or gloves to minimize direct contact and avoid grid contamination.
