C-11 Pro2
all in one C-11 radiotracer production lab The C-11 Pro2 is our next generation synthesizer designed from years of R&D to simplify the routine production of C-11 radiotracers. 11CO2 is trapped at room temp. and rapidly released using a volume optimized molecular sieve column. Capable of producing either methyl-iodide or methyl-triflate via the "wet" chemistry method, labelling is performed by traditional reaction vial or room temp. loop labelling* and comes with built-in HPLC purification. The C-11 Pro2 is the complete solution for all your C-11 production requirements in the one device.
The C-11 Pro2 has enabled our lab to synthesize an array of more than 10 different 11C compounds, with excellent day-to-day reliability and very good yields and specific activity Dr. Didier Le Bars

Final Injectable Radiotracer
Disposable S.P.E. Reformulation Cassette
Simplify GMP requirements
The sterile disposable S.P.E. (solid phase extraction) product reformulation cassette and reagent set help avoid cross-contamination and ensure reproducible results. By using non-proprietary components, the C-11 Pro2 enables users to modify and develop their own cassettes.



Disposable Reactors
Two disposable 1.1mL tapered bottom glass reactors allow low volume (as low as 70uL) reactions and reduce cross-synthesis contaminants which ensures reproducible results. Fully Automated Wash-Up
Immediately post synthesis, the C-11 Pro2 preforms a fully automated wash-up procedure with 3 different solvents to clean all fixed valves and tubing.
Features Designed to Optimize the C-11 Radiosynthesis And make life easier for the radiochemist!
Molecular Sieve Column
The volume optimized molecular sieve column enables room temperature concentration of the cyclotron produced [11C]C02 and rapid heating for quick release. SIlver Triflate Column
The built-in silver triflate column allows on-line conversion of [11C]methyl-iodide into [11C]methyl-triflate.
Each disposable reactor has a positionable centre disposable needle that can be moved up or down to suit the chemistry step. Reactor 1 is used to generate [11C ]methyl-iodide via the "wet chemistry" method. Reactor 2 is used to preform the traditional labelling reaction method with the desired synthon.


Loop Reaction
In addition to the traditional reaction vial labelling method, the C-11 Pro2 allows labelling via the room temperature loop labelling method developed by Dr. A. Wilson.
Room Temperature Loop Reaction


Multi-Position Rotary Valves
All fluidic process valves are robust multi-position rotary types that permit optimized fluid flow paths. 3-Position Stopcock Actuators
Each rotary actuator for the disposable cassette's stopcock taps can be rotate to all three positions.
13.6 bar pressure rating
20uL internal volume
Compact HPLC System
The C-11 Pro2's compact HPLC contains all the features needed to purify compounds.
50mL/min pump head with integrated pressure sensor. Fibre Optic UV/VIS Detector
Variable wavelength and fibre optic connection to the flow cell.
Only the remote fibre optic flow cell is mounted inside the hotcell which frees up valuable hotcell space compared to traditional UV detectors.

Compact Dimensions
Install the C-11 Pro2 into virtually any hotcell.
Width 510mm x Height 434mm x Depth 340mm No longer do you need a large and expensive research hotcell to house all the equipment needed for the complete synthesis of C-11 compounds. The C-11 Pro2 can fit into compact hotcells which reduces your labs hotcell costs.
Surprising Benefits
Not your average C-11 radiosynthesizer.
Yield Specific Activity
Multi-Synthesis Capability
Preform multiple radiosynthesis in one day thanks to the use of disposable components and fully automated synthesizer wash-up.
Save time and and eliminate the hassle by not needing to perform manual cleaning procedures with the C-11 Pro2. High Yield + High Specific Activity
Our users have discovered that along with high radiochemical yields, the C-11 Pro2 can achieve high specific activity results as well.
This is due to the C-11 Pro2's design and optimized "wet" chemistry process.
