Multi-Step 18F Radiotracer Development & Production Platform

The FlexLab is the most versatile 18F radiosynthesizer specifically suited to the research, development and fully automated production of multi-step radiotracers. The FlexLab allows the radiochemist to fully automate the radiosynthesis of multi-step compounds thereby improving synthesis yields, simplifying daily production and most importantly reducing the operators radiation exposure by completely eliminating the need to perform any manual processes.

Synthesis Possibilities

The FlexLab is the only radiosynthesizer that is able to fully automate all the following synthesis steps:










Reagent vials


Process valves



Reaction purification



HPLC Valves



HPLC pump




HPLC UV detector
