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.



Superior Sample Support for TEM

These Formvar/Carbon-coated nickel grids are engineered to meet the demanding standards of electron microscopy. The smooth, robust mesh and ultra-thin films provide outstanding support for ultrafine samples, ensuring minimal background interference and high resolution results. Widely used across biological, material science, and nanotechnology sectors, these grids facilitate reliable specimen mounting and imaging.


Precision Manufacturing and Consistent Quality

Every pack contains 50 grids produced from lab-grade, high purity nickel and coated with precisely controlled layers of Formvar and carbon. The surface finish is carefully optimized for smoothness and uniformity, guaranteeing consistent imaging performance and reducing issues associated with variability or grid artifacts in sensitive analyses.


Long-Term Stability and Easy Handling

With indefinite shelf life under proper storage, these grids retain functionality and structural integrity over time. Handle grids with tweezers and avoid touching support films directly to prevent contamination or physical damage, ensuring prolonged usability and maximal data quality from every specimen prepared.

FAQs of Formvar/Carbon on 75 Mesh Nickel (Pack of 50):


Q: How should Formvar/Carbon on 75 mesh nickel TEM grids be handled and stored?

A: Always use clean tweezers to handle the grids, avoiding direct contact with the support films to prevent contamination or damage. Store the grids in a clean, dry environment at ambient temperature; under proper conditions, they have an indefinite shelf life.

Q: What types of samples are suitable for mounting on these support films?

A: These grids are compatible with a broad range of specimens, including biological tissues, polymers, and nanomaterials. Their semi-transparent Formvar/carbon film provides excellent support and minimal background, making them ideal for electron microscopy sample preparation.

Q: When is it beneficial to use a Formvar/Carbon-coated nickel grid over other support types?

A: Use these grids when your application demands superior mechanical stability, chemical resistance, and high purityparticularly for high-resolution imaging of delicate or thin specimens in transmission electron microscopy.

Q: Where are these TEM grids typically used?

A: They are widely applied in laboratories and research institutes focused on biological sciences, materials analysis, and nanotechnology, mainly for sample mounting and observation under transmission electron microscopes.

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

A: Mount your specimen onto the support film using appropriate sample preparation techniquessuch as deposition, drop-casting, or sectioningensuring minimal disturbance to the thin Formvar/carbon film during handling. Proper technique ensures quality imaging results.

Q: How does the manufacturing process ensure grid consistency and quality?

A: Each grid is produced from high purity nickel to laboratory standards, coated with Formvar through casting and topped with a carbon layer via vacuum evaporation, delivering a smooth, uniform finish across batches.

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

A: These grids offer a stable, inert surface with minimal background signal, high mechanical strength, and broad compatibility with various sample types, enhancing reproducibility and accuracy in electron microscopy investigations.
