Product Description

These thin cast films of Formvar have been strengthened with the addition of a layer of evaporated carbon on gold 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 gold grids feature a Formvar/Carbon film that offers a reliable, smooth surface for ultra-thin biological or material sections in TEM. The films uniform coating minimizes sample distortion and maximizes image clarity, essential for laboratory and research grade results.

Designed for Versatility and Compatibility

Compatible with most biological and material TEM applications, these grids are suited for a wide range of sample types. The conductivity from gold and carbon allows detailed imaging, while the non-toxic and inert nature ensures safety during handling.

Precision Manufacturing and Consistent Quality

Produced to stringent TEM grid standards, these grids offer uniform mesh and coating thickness. This precision manufacturing results in consistent sample support across all grids in the pack, meeting the needs of exporters, importers, and laboratory professionals.

FAQs of Formvar/Carbon on 400 Mesh Gold (Pack of 50):

Q: How are Formvar/Carbon on 400 Mesh Gold grids used in TEM?

A: These grids are placed in TEM sample holders to support ultra-thin sections of biological or material samples, allowing for high-resolution electron microscopy imaging.

Q: What is the benefit of the Formvar/Carbon film coating on gold grids?

A: The Formvar/Carbon film delivers a smooth, conductive and uniform surface, reducing sample charging, distortion, and providing enhanced image clarity in TEM analysis.

Q: When should I select a 400 mesh grid for my microscopy work?

A: 400 mesh grids are ideal when you require a fine support structure for holding ultra-thin sections, especially for detailed TEM analysis in research or diagnostic applications.

Q: Where should these grids be stored to maintain quality?

A: Store the grids in a dry, dust-free container at room temperature to prevent contamination or damage to the thin Formvar/Carbon film coating.

Q: What process is involved in manufacturing these support grids?

A: The gold mesh is produced with high purity, then coated uniformly with Formvar and carbon layers. This precision process ensures smoothness, conductivity and consistent thickness for reliable sample support.

Q: How does the grids excellent conductivity benefit TEM applications?

A: Excellent conductivity from the gold and carbon materials minimizes charging artifacts, enabling more accurate and clearer TEM images for material and biological samples.

Q: Are these grids compatible with all types of TEM samples?

A: Yes, they are designed to support most biological and materials TEM applications due to their inert, non-toxic composition and universal grid size.
