About Us

Our History

Quantifoil Micro Tools GmbH was founded in 1999 in Jena, Germany to manufacture and market proprietary QUANTIFOIL^® support films for electron microscopy. Our Holey Carbon Films were the first perforated support films with predefined hole size, shape and arrangement on the market. Over the years, we have successively expanded our product range and QUANTIFOIL^® support foils are now available in 25 different geometries on a full range of TEM grid materials and designs.

Quantifoil Today

Quantifoil has grown continuously and, in 2012, we moved into our new facility in Großlöbichau near Jena to accommodate the future technical requirements of the growing business. In July 2019, Quantifoil became part of SPT Labtech, enabling us to continue to invest in the future of cryo-electron microscopy. Currently, we're looking forward to the launch of the revolutionary HexAuFoil^® sample supports that will improve every image later this year.

We now employ more than 20 highly-qualified staff, serving researchers in industry and academia from more than 30 countries, both directly and via our extensive distributor network. To ensure the quality of our QUANTIFOIL^® support films and other carbon coated grids, every support film and base grid is checked by our skilled technical staff using optical microscopy, and additional checks are made by electron microscopy.

As a manufacturing firm focused on supplying the latest innovations at the highest quality, it is our pleasure to share our experience in micro-structuring with the community and we are valued for our willingness to respond to special requirements. Our product range has continued to expand, now encompassing the UltrAuFoil^® range of holey gold supports on gold grids which, by reducing beam-induced motion, allow data collection at the highest resolutions on ever smaller molecules.
