PELCO® TEM grid Support Films of Formvar, Formvar/Carbon, Carbon, and Silicon Monoxide are available on the following 3.05mm O.D. grids: 0.4 x 2mm single slot Cu, 75 mesh Cu, 200 mesh Cu,Ni or Au, 200 mesh Hex Mo, 300 mesh Cu, Ni or Au, 300 mesh Hex Mo, and 400 mesh Cu, Ni, Au, Al, Ti and stainless steel.

Support films on the finer mesh grids can withstand considerable handling during specimen preparation. Those on slot and 75 mesh grids require more gentle handling and are ideal for those applications requiring large viewing areas without grid bar interference.

Our popular line of PELCO NetMesh™ Grids (our trademarked lacey films) are available on 200, 300 and 400 mesh grids. These robust films allow for viewing of specimens without interference from underlying support film material.

The complete PELCO® line of support films meets the requirements of most applications in all fields of electron microscopy.

2. Formvar, Stabilized with Carbon: A Formvar film covered with a "light" layer of carbon. The heat and electrical conducting properties of carbon help to stabilize the Formvar films when exposed to the electron beam. This is a resilient, all-purpose specimen support film, ideal for mounting thin sections and for applications using lower ranges of magnification. The 200M-TH grids (Prod. No. 01803 and 01803-F,01803G and 01803G-F), plus the 300M-TH grids (Prod. No. 01804G and 01804G-F) are thicker and more rigid than normal and useful for many applications - particularly where a lot of grid handling is involved.

3. Carbon Type-B: A Formvar film coated with a “heavier” layer of carbon. This is the strongest and most versatile support film we produce. It is stable in the EM under all operating conditions including high magnification with high beam intensity. The films can withstand vigorous specimen preparation techniques. If the carbon surface is hydrophobic, specimen suspensions can be applied to the Formvar surface.

4. Carbon Type-A: Carbon support films with a removable Formvar on the opposite side of the grid. When the Formvar is removed, by dipping in solvent, a pure carbon film remains. (Note: The Ultrathin Carbon Film on a Lacey Carbon Support Film, Prod. No. 01824, has no Formvar backing.) These films are stable under all EM operating conditions and are for use where the presence of a Formvar layer cannot be tolerated. Pure carbon films tend to be more delicate than those with a Formvar backing and require more delicate handling during specimen preparation than most other support films.

(c) Ultrathin Carbon Film on a Lacey Carbon Support Film: Pure carbon support films with no Formvar backing. This new product has an even thinner carbon film which is mounted on a Lacey carbon film. The carbon support layer lying over the holes is less than 3nm in thickness and is the thinnest support film available. It is particularly useful for high resolution microscopy of low contrast particles and is also ideal for use with the Energy Filtering TEM.

5. Pure Carbon Film: Carbon films with a thickness of 15-25nm with no Formvar used during manufacturing. Completely free of Formvar. Carbon films are thin and highly transparent to electrons. They exhibit very fine grain and minimal interference with specimen structure. Films are ready to use upon receipt. The pure carbon films tend to be more delicate than support films with a Formvar backing and require more delicate handling during specimen preparation. Available on Cu, Ni, and Au TEM grids with 200, 300, and 400 mesh. Mo grid only available in 200 mesh hex. Al and Ti only available in 400 mesh. PELCO® Technical Note, Pure Carbon Film (143KB PDF)

6. Silicon Monoxide: Silicon monoxide produces a highly resilient support film which can withstand vigorous specimen preparation techniques. It has low background contrast, is stable under the electron beam and is less hydrophobic than carbon. We offer two types of silicon monoxide support films:

 (a) Formvar Stabilized with Silicon Monoxide: A Formvar film coated with a “light” layer of silicon monoxide.

(b) Silicon Monoxide Type-A: Silicon monoxide with a removable Formvar backing on the opposite side of the grid. When the Formvar is removed, by dipping in solvent, a pure Silicon Monoxide film remains. These films are stable under all EM operating conditions and for use where the presence of Formvar cannot be tolerated. Pure Silicon Monoxide is more delicate than those with Formvar backing and require more careful handling during specimen preparation.

7. Lacey Support Films - PELCO NetMesh™ Grids:

Lacey Support Film

A lacey network support film. The holes in the lacey support film vary in size from less than a quarter micron to more than 10 microns making them ideal for any type of specimen. Lacey support films are extremely strong and withstand vigorous specimen preparation treatment. The specimen material is supported by the film network but lies across or protrudes into the holes of the mesh. This allows high definition imaging without the effects of underlying support material. Lacey films can be used for specimens ranging from large crystals and other particulate material to virus particles. Smaller particles, such as viruses or bacteria, tend to adhere around the inner edges of the holes, an ideal situation for high resolution microscopy. Lacey films are also ideal for selected area electron diffraction imaging. We offer four types of lacey film.

See the Support Film / Substrate Application Guide at top of page.
