TEM Support Films: overview and selection guide
Large selection of high quality, ready to use TEM support films which save valuable time. The traditional formvar and carbon based support films are made with dedicated equipment in a clean environment and are all checked with a TEM before being shipped. The EM-Tec silicon nitride TEM support films are made using the latest semiconductor manufacturing techniques are ideal for experiments on a robust support film and high temperature applications. The EM-Tec research-ready graphene films present the thinnest TEM support films. All TEM support films are supplied in a TEM grid storage box.
The EM-Tec TEM support film selection guide
The EM-Tec support film selection guide has been compiled to help selecting the most appropriate support film for the application. It is intended as a selection guide, for special requirements you might choose a different TEM support film than the suggestion in the table.
