Bruker A300 A200 EPR spectrometer

 A spectrometer is a series of products developed by Bruker to meet scientific research requirements and economical budget.The A300 is a modular design, while the A200 is a compact, highly integrated system. Series A spectrometer is a multifunctional instrument in studying electron paramagnetism of gas, liquid and solid samples.

As the operation mode of A spectrometer is diverse and flexible, it is suitable for both routine test work and high-end scientific research.

A spectrometers have the highest sensitivity of their kind. Because of the use of the latest digital technology, it improves the user interface of the spectrometer, and can provide users with a large number of software and hardware tools.The  A spectrometer is the latest product from brook EPR research and development, which created the EPR world standard 25 years ago.
