Formvar support films

Formvar only TEM support films on TEM grids are an excellent solution for imaging fragile sections in the TEM, including ultra-thin cryo-sections.

Formvar thickness is approximately 5-7 nm and offers a mechanically stable support film. Formvar is a polymer-type film and is generally hydrophilic, which gives good dispersion and deposition of particles on the surface of the Formvar film.

Formvar only TEM support films are available on 50, 75,100, 150, 200, 300, 400 mesh and larger slotted copper, nickel and gold TEM grids with a 3.05mm diameter.

TEM support film grids are available in pack sizes of 25, 50 and 100/box.
