TalaveraScience is the Senior Sales Consultancy for Client throughout Europe, the Middle East, India and Australasia.

Bridge12 Technologies was founded almost two decades ago by Dr Jagadishwar Sirigiri and Dr Thorsten Maly, both former scientists from MIT and each with extensive experience in high-frequency terahertz (THz) sources, such as gyrotrons, microwave technology and magnetic resonance spectroscopy.

Bridge12 Technologies develops and provides THz/microwave technology including active and passive components such as gyrotrons, replacement gyrotron tubes and transmission lines for Dynamic Nuclear Polarization (DNP) enhanced NMR spectroscopy and microwave tools such as for microwave frequency measurement.

Bridge12 Technologies products find their application in magnetic resonance (EPR, DNP and NMR) in both academic research and in industrial research and development institutions. Bridge12 Technologies has supplied instruments and other microwave products to research groups across the United States of America and elsewhere in Japan, South Korea, Germany and Israel, amongst others.

The EPR business of Bridge12 was acquired by Bruker Biospin in 2024. Bridge12 Technologies continues to provide microwave and terahertz components and sources for DNP-NMR spectroscopy.

Bridge12 Technologies is located near Boston in Massachusetts, USA.

Bridge12 Technologies Gyrotrons for Dynamic Nuclear Polarisation

Bridge12 Technologies DNP MAS NMR Gyrotrons

One of the core areas leading to the formation of Bridge12 Technologies was their expertise in building high power microwave sources such as gyrotrons. This included expertise in gyrotrons for solid state Dynamic Nuclear Polarisation Magic Angle Spinning (DNP MAS) NMR spectroscopy. Today, Bridge12 Technologies build gyrotrons for other application areas, however, they have stayed true to their original mission of providing microwave sources for DNP MAS NMR.

The Bridge12 Technologies DNP MAS gyrotron systems are available to replace microwave sources on existing DNP MAS NMR instruments or are available for those scientists wanting to assemble their own DNP MAS capability on an existing spectrometer, typically for 300 - 900 MHz 1H solid state NMR spectrometers.

Bridge12 Technologies GHz/THz Frequency Measuring Instruments

Do you know the exact frequency emitted by your GHz/THz source?

Would you like to track the frequency during your experiment? Bridge12 Technologies have the perfect instrument to do this and is ideal for troubleshooting solid state DNP NMR experiments; the Bridge12 Frequency Measurement System (FMS).

The Bridge12 Technologies FMS is a well documented and supported turn-key frequency measuring system consisting of a heterodyne broadband receiver capable of measuring frequencies from 26 GHz to 500 GHz (depending on the input mixer). The Bridge12 Technologies FMS is controlled through a simple software interface with two modes: measure and; track and can be installed on a gyrotron control system, the EPR spectrometer computer or a Windows-based computer.
