Pioloform carbon support films

Pioloform carbon TEM support films are more robust than pioloform or carbon only films. Pioloform is sometimes preferred over Formvar due to its higher mechanical and thermal stability and lower density, which can both help reduce electron scattering and give better transparency. The thin carbon film on top of the Pioloform stabilises the support film when working with voltages above 120kV and/or for working over prolonged times on the same area. However, carbon is hydrophobic from itself so when depositing particles, the support film needs to be treated to make the surface hydrophylic. Making support films hydrophylic can achieved with a glow discharge device, plasma cleaner, such as the Tergeo-EM plasma cleaner, a UV lamp or brief immersion in 70% alcohol. For TEM-Tomography applications which could damage or deform the sample, we suggest coating the sample with a few nanometers of thin carbon.

Pioloform carbon TEM support films also offer a good solution in cases where a carbon only film would be too fragile to withstand pre-treatment and/or additional processing. The thickness of the Pioloform film is around 5-7 nm and the carbon film around 7-10 nm. The carbon film is on top of the Pioloform film.

Pioloform carbon TEM support films are available on 50, 75, 100, 150, 200, 300, 400 mesh and larger slotted copper, nickel and gold TEM grids. See the table below for details of Pioloform carbon support films, There are pack sizes of 25, 50 and 100 in a TEM grid box.
