Ted Pella introduces Substratek; a set of innovative, electron transparent, metallic TEM substrates. The ultrathin substrates are ideally suited for use as integrated research platforms in applications as diverse as: electrochemistry, nanofabrication, micro-contact printing, nano-crystal growth and X-ray analysis of carbon containing materials. They allow for subsequent TEM examination without the need for time consuming and expensive specimen preparation. Available are Au, Pt and Pd with 23 nm thickness and TiOx with 15 nm thickness on 300 and 400 mesh TEM grids. The Au, Pt and Pd substrates are deposited on gold TEM grids compatible with electrochemical processes. The TiOx substrate is deposited on copper TEM grids. TiOx is a bio-compatible material ideal for life-science applications.
