Product Description

Formvar coated grids without a carbon layer are suitable for TEM applications up to 100kV. The films are available on copper grids. Nickel and gold grids are also available.

Supplied as 25 grids in a grid box.

High-Purity Support Grids for TEM

These copper grids coated with Formvar film provide exceptional stability and clarity for transmission electron microscopy. With a nominal film thickness of 2025 nm, they support delicate ultrathin sections and fine particulate samples, ensuring reliability in laboratory and research environments.

Optimized Handling and Longevity

The Formvar film is robust yet delicate, requiring careful handling with anti-static tweezers to avoid physical damage. When stored in a cool, dry, dust-free environment, the grids maintain optimal quality and are shelf-stable for over two years, making them ideal for long-term laboratory use.

FAQs of Formvar on 3mm 300 Mesh Cu Grids (Pack of 25):

Q: How should I handle Formvar on 3mm 300 Mesh Cu Grids to avoid damaging the film?

A: Always use anti-static tweezers or tools when handling these grids to prevent physical damage to the Formvar film. Avoid touching the film directly with fingers, and minimize exposure to dust and static electricity during sample preparation.

Q: What is the primary benefit of using Formvar-coated copper grids in TEM analysis?

A: Formvar-coated copper grids offer stable support for ultrathin sections and particulate samples, providing high clarity and durability during transmission electron microscopy, which is essential for accurate imaging in both biological and material sciences.

Q: Where should these grids be stored to ensure their shelf life exceeds two years?

A: To maximize shelf life, store the grids in a cool, dry, and dust-free environment, away from direct sunlight or sources of moisture and contaminants. Proper storage preserves film integrity for over two years.

Q: What is the process for preparing these grids for electron microscopy sample loading?

A: Prepare grids by placing them onto a clean surface using anti-static tweezers, ensuring that the Formvar film remains intact. Apply samples gently on the film using suitable protocols for TEM, and avoid excessive pressure during mounting.

Q: Are these Formvar copper grids compatible with both biological and material science TEM studies?

A: Yes, the Formvar film-coated 300 Mesh Cu grids are designed for microscopy-grade applications and are well-suited to support samples used in biological and material science TEM analyses.

Q: What should I do if the Formvar film appears discolored or damaged before use?

A: Inspect grids before use; if the Formvar film shows noticeable discoloration, tears, or contamination, select another grid from the pack to avoid compromised results. Film should generally be transparent to slightly off-white in color.
