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 Applications

These Formvar/Carbon-coated nickel grids are designed to deliver optimal support when preparing samples for transmission electron microscopy. Their uniform thin films and precise mesh size ensure stability and clarity during imaging, making them ideal for detailed ultrastructural studies in biological and material science research.

Laboratory Grade Composition and Purity

With 99.9% purity nickel grids and meticulously coated Formvar/Carbon films, these grids meet stringent electron microscopy standards. Their smooth surface finish and high chemical stability safeguard the samples integrity, offering reliable performance during demanding analyses.

Simple and Safe Handling

Each grid is engineered for secure handling using anti-static tweezers, reducing the risk of contamination or damage. Packaged as 25 grids per vial, they should be stored in a dry, dust-free environment to maintain optimal film quality, making them a fuss-free consumable for microscopy laboratories.

FAQs of Formvar/Carbon Films on H7 Nickel Grids (Pack of 25):

Q: How should I handle Formvar/Carbon Films on H7 Nickel Grids during sample preparation?

A: Use anti-static tweezers to manipulate these grids to minimize mechanical stress and prevent contamination; avoid direct contact with fingers to preserve the integrity of the thin films.

Q: What is the main benefit of using these grids in TEM analysis?

A: Their uniform Formvar/carbon coatings and high purity nickel grid provide a stable, smooth support for specimens, enhancing imaging resolution and sample reliability in transmission electron microscopy.

Q: When is it appropriate to use these Formvar/Carbon-coated nickel grids?

A: Employ these grids for TEM sample preparation when working with biological tissues or materials science samples that require reliable support films and high purity substrate for precise electron microscopy imaging.

Q: Where should I store the pack of nickel grids to preserve their quality?

A: Store unopened vials in a dry, dust-free location away from humidity and mechanical stress. This ensures the thin films remain intact and the grid surfaces stay clean for high-quality microscopy results.

Q: What process is used to apply the Formvar and carbon coatings on the grids?

A: The coatings are deposited by evaporation and floating techniques, which produce highly uniform, smooth films and ensure optimal electron transparency for microscopy applications.

Q: How do I dispose of Formvar/Carbon Films on Nickel Grids after use?

A: Despite being non-toxic under normal laboratory use, dispose of used grids according to local laboratory protocols for metal and polymer consumables, ensuring compliance with relevant safety and waste guidelines.
