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.

High-Quality Construction

Each grid combines a robust 300 mesh gold substrate with a Formvar/Carbon support film, delivering smooth surfaces and low imaging background. This ensures minimal interference and superior sample visualization across diverse TEM applications.

Optimized for TEM Analysis

Designed for compatibility with most TEM holders, these grids maintain stability under the electron beam and resist shrinkage. Researchers benefit from reliable mounting and imaging for both biological and material science samples.

Reliable Packaging and Shelf Life

Every pack contains 25 grids, carefully housed in grid boxes that protect against damage. With a shelf life of at least two years when stored in dry, room-temperature conditions, they offer long-term usability and secure handling.

FAQs of Formvar/Carbon on 300 Mesh Gold (Pack of 25):

Q: How should Formvar/Carbon on 300 Mesh Gold grids be handled during sample preparation?

A: These grids feature anti-static properties but require careful handling with tweezers and gloves to avoid film damage and contamination, ensuring reliable support for TEM samples.

Q: What is the main benefit of using gold substrate grids with Formvar/Carbon films for TEM analysis?

A: The gold substrate provides enhanced stability and electrical conductivity, while the Formvar/Carbon film offers a smooth, uniform surface, resulting in low backgrounds and clearer electron microscopy images.

Q: When is it recommended to replace Formvar/Carbon on 300 Mesh Gold grids?

A: It is advisable to replace grids after noticeable physical damage or contamination, although they remain stable for at least two years if stored in a dry and room-temperature environment.

Q: Where are these grids commonly used in research?

A: They are widely utilized in laboratories specializing in biological, nanotechnology, and materials science research for mounting specimens in TEM studies.

Q: What process should be followed for long-term storage of these grids?

A: Grids should be kept in their protective grid box, in a dry place at room temperature, to maintain film integrity and prevent static damage or contamination.

Q: Are Formvar/Carbon on 300 Mesh Gold grids compatible with all TEM holders?

A: Yes, the 3 mm standard TEM grid diameter ensures compatibility with most transmission electron microscope holders, supporting versatile use across instruments.

Q: What advantages do these TEM grids offer for sample imaging?

A: Their high purity, smooth film, and robust support minimize interference, providing sharp, low-background images for accurate sample analysis and reliable research results.
