C-11 Pro2

Complete C-11 radiotracer production lab

C-11 Pro2 radiosynthesizer

The C-11 Pro2 is our next generation synthesizer designed from years of R&D to simplify the routine production of 11C 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 11C 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

[11C] Methyl-Iodide

 

[11C]Methyl Iodide is produced in

Reactor 1 via the “wet chemistry”

method and it achieves a > 85%

conversion rate from [11C]carbon

dioxide to [11C]methyl-iodide.

 

[11C] Methyl-Triflate

 

The built-in silver triflate column

allows on-line rapid conversion

of [11C]methyl-iodide into [11C]

methyl-triflate.

 

 

Loop Labelling

 

In addition to the traditional reaction vial

labelling method, the C-11 Pro2 allows

labelling via the room temperature loop

labeling method developed by A. Wilson.

 

 Benefits: Generally less by-products are produced as the reaction is done at room temperature resulting in higher labelling yields.

 

 

 

Reactor Labelling:

 

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. HPLC loop is loaded with the reaction  mixture using the built-in syringe drive.

 

Reactor 1

Reactor 2

Two disposable 1.1mL tapered bottom glass reactors allow low volume (as low as 75uL reactions and reduces cross-synthesis contaminants which ensures reproducible results.

High Yield & High Specific Activity

No need to compromise -  both can be achieved.

Yield

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.

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.

Multi-Synthesis Capability

Preform multiple radiosynthesis in one day thanks to the use of disposable components and fully automated synthesizer wash-up.
