multi-step F-18 radiotracer production lab The FlexLab is the most versatile F-18 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 of preform any manual processes.
For complex multi step F-18 radiotracer research & development, the FlexLab has been invaluable Dr. Uwe Ackermann

Fibre Optic UV Flow Cell
Only the remote fibre optic flow cell is mounted inside the hotcell which frees up valuable space compared to a standard UV detector. HPLC Low Pressure Gradients
Easily perform fully automated quaternary L.P.G. solvent elutions during your radiosynthesis. All parameters are defined in your recipe file. Eliminate Manual Solvent Mixing
Quaternary L.P.G. eliminates the need for manual mixing of your HPLC eluent - It's all done on-line.
Flexible Reactors
Easily swap between the standard 20mL reactor and the small volume 2mL reactor.
Open up new possibilities with the quick change small volume reactors by simplifying the transition to peptide labelling.
LN2 Main Reactor Cooling
Extend the cooling range of both main reactors to -80°C by combining it with our LN2 cooling option. Quad Reactors
Add unparalleled quad reactor capabilities to the FlexLab. The quad reactor option adds heating/cooling, radioactivity monitoring and magnetic stirrer bar mixing to both intermediate vials.
Small volume 2mL reactor Standard 20mL reactor Reactors available in either standard borosilicate glass or high purity glassy carbon. Heating to 220°C & vortex tube compressed air cooling to ≈ 8°C.
Compact Dimensions
Install the FlexLab into virtually any hotcell.
Width 494mm x Height 466mm x Depth 416mm Reduce your labs hotcell costs!
No longer do you need a large and expensive research hotcell to house all the equipment needed for complex multi-step synthesis.
The FlexLab easily fits into compact hotcell's with internal dimensions as small as 72cm x 60cm x 60cm (WxHxD) which can substantially reduce your laboratories costs.
Complete & precise monitoring.
Radioactivity Detectors
Monitor every step of the synthesis with 10 collimated radioactivity detectors.
CsI(TI) crystal PIN photodiodes provide a linear response across a large radioactivity range. HPLC Injection Fluid Detectors
Product injection into the HPLC loop's is controlled by two software calibrated optical fluid detectors. They allow on the fly adjustment of the detection threshold so that you never miss your product injection.
Open User Interface System control & visual synthesis recipe development all in one platform.
C-11 Pro2 software interface
The user interface combines both powerful features, yet easy to use tools for both daily operation and synthesis recipe development.
Easy to use open software interface for easy tracer development
Guides you step-by-step during the synthesis
Can be installed on multiple computers for remote synthesis
Recording of all process variables and report generation (21 CFR Part 11 & GMP compliant)
Traditional PC or Touch Screen Tablet Control
Built-in remote diagnostics enabling simplified troubleshooting
Synthesis Reports
Generate and print synthesis reports to satisfy you labs documentation and GMP requirements Real-Time Sensors Trends
All sensor information can be displayed graphically in real-time trends Historical Data Review
Review previous synthesis results as trend graphs with data analysis function,
