Portable, 4-channel SPR

Thanks to a compact design, your analytical tests will be faster by reducing sample preparation time and accessing SPR  at your bench or on the field. Our unique technology can detect and monitor not only biomolecule such as small peptides and large proteins but also pesticides, small drugs, self-assembled monolayer and nanomaterial.
