Product Description

These thin cast films of Formvar have been strengthened with the addition of a layer of evaporated carbon on copper 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 either in packs of 25 or 50 grids in a grid box depending on each particular product.

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

Superior Imaging Support for Electron Microscopy

These Formvar/Carbon-coated copper grids deliver a consistently smooth support film essential for high-resolution TEM imaging. The combination of Formvar and carbon layers ensures minimal background interference, allowing for clearer visualization of sample structure. With anti-static packaging and careful manufacturing standards, each grid maintains its integrity for accurate research applications.

Engineered for Laboratory Precision and Compatibility

Manufactured to meet electron microscopy industry standards, these grids fit standard TEM holders and offer a 200 mesh copper base for optimal sample support. Their fragility requires handling with tweezers, while their neutral pH and non-poisonous properties make them suitable for safe laboratory environments. Ideal for researchers, the grids are insoluble in water and offer durability through high-purity thin films.

FAQs of Formvar/Carbon on 200 Mesh Copper (Pack of 25):

Q: How should Formvar/Carbon on 200 Mesh Copper grids be handled during preparation?

A: Due to their delicate structure, these grids should always be handled with tweezers. Direct finger contact may damage the thin support film and compromise sample integrity.

Q: What is the main benefit of using the Formvar/Carbon-coated copper grids in TEM applications?

A: The dual-layer coating provides stable, high-purity support, reducing background noise and enhancing the clarity of electron microscopy images for precise sample analysis.

Q: When is the use of this TEM support grid recommended?

A: Use these grids for laboratory research requiring high-quality TEM sample support, particularly when clear visualization of ultrathin specimens is essential. They are not recommended for clinical or diagnostic purposes.

Q: Where should these grids be stored to ensure optimal performance?

A: Store grids in a dry, dust-free environment, ideally within the provided anti-static container or grid box to prevent contamination and mechanical damage.

Q: What is the process for preparing samples on these grids for TEM analysis?

A: Typically, samples are placed on the surface of the grid using micropipettes or blotting techniques. After mounting, the grid is allowed to air dry or undergo further processing as required for TEM investigation.

Q: Are these grids compatible with all TEM holders?

A: Yes, the grids are designed to be compatible with standard transmission electron microscopy holders, facilitating ease of use across laboratory equipment.
