High-Tech Gründerfonds invests in KonTEM GmbH

Examination of biological specimen in a transmission electron microscope is complicated and time-consuming. Due to the weak interaction between the specimen and the electron beam, the images show very low contrast and appear almost transparent. KonTEM has managed to transfer the phase contrast application from light microscopy into electron microscopy in such a way that it can be used in TEM routine application.

The KonTEM phase contrast system consists of two main components: the phase plate and the automatic high precision positioning device. The phase plate is the centrepiece of the system. It is an ultra-thin, perforated membrane which influences the phase of the scattered electrons; the object appears focused and with high contrast. The positioning device allows to precisely placing the phase plate into the electron beam, a matter of nanometers. With its modular design, the system can be easily adapted to fit into all new and already installed TEM models.

„The financing from the High-Tech Gründerfonds facilitates a fast and comprehensive market penetration, a prerequisite for a sustainable competitive advantage” says Joerg Wamser, the managing director of KonTEM.

“The underlying technology was researched at the Max Planck Institute of Biophysics in Frankfurt and developed into a marketable product at the research center caesar. KonTEM showcases, that fundamental research as done by the Max-Planck-Gesellschaft can be a basis for innovative and marketable products. We are very pleased to enter into yet another cooperation with the HTGF, states Dr. Florian Kirschenhofer, Start-up Manager at Max-Planck-Innovation, the technology transfer organisation of the MPG.

Dr. Andreas Olmes, Senior Investment Manager at the High-Tech Gründerfonds is looking forward to his work with the new portfolio company: “The modular design of the system allows KonTEM to quickly penetrate its target market and to also retrofit a large number of already installed microscopes. Similar to the “razor-blade” business model, the constant replacement of phase plates generates recurring revenues. In addition, KonTEM has a sustainable competitive advantage through its patent and license portfolio.”

Prof. Dr. U. Benjamin Kaupp, Scientific Director of caesar: “The many awards underline that KonTEM offers an outstanding future-oriented technology.”
