简单介绍：
PELCO® 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 or Ni, 300 mesh Cu or
详情介绍：

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 NetMesh™ Grids (our trademarked lacey films) are available on 200 and 300 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.
 

Thickness of Support Films
The following is a guide to the relative thickness of the support films. The actual thickness varies depending on a number of factors during the deposition process.
 

1. Formvar Layer, measured with a Tencor Alpha-Step 200 profilometer:
All Formvar Films - 30 to 60nm.
2. Carbon Layer, measured with a Film thickness Monitor during evaporation:
On Formvar Stabilized with Carbon - 5 to 10nm
On Carbon Type-A - 15 to 25nm
On Carbon Type-B - 15 to 25nm
On Ultrathin Carbon Type- A - 3 to 4nm
On Ultrathin Carbon Film over Holey Carbon Film - under 3nm

1. Formvar: A film of pure Formvar, with no stabilizing coating. These films are useful for your customized coating of stabilizing material or for the support of thin sections.

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) 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.
