188W/188Re Generator
Production of high-energy beta emitting rhenium-188
Product Overview
The OncoBeta® 188W/188Re Generator is based on an alumina column. The longer-lived mother radionuclide 188W is adsorbed on the column material while the daughter radionuclide 188Re is selectively eluted from the generator with sterile isotonic solution as sodium perrhenate (Na188ReO4).
Use Cases
The 188W/188Re Generator can be used for radiolabelling reactions or directly as a high dose liquid radioactive source. Not for human use.
Main Features
