EcoSynth is a solution provider for the chemical challenges of tomorrow. As an extra tool, flow chemistry (lab equivalent of continuous processing) has several advantages over the traditional batch chemistry:
Efficient |
Flexible |
Safe |
Higher yield and purity | Different chemistries/reactors on one instrument |
Excellent heat transfer |
In-situ analytical |
Less restrictions on minimum fill volumes |
Low reactor volume and hold up time |
Better process control |
Scaling out by adding units in parallel |
In-situ generation and consumption of dangerous compounds |
Shorter time to commercial launch |
In order to meet a wide range of synthesis requests (using traditional as well as unconventional activation techniques), Ecosynth is equipped with several flow instruments from different vendors.

Photochemical flow reactors including the HANU-reactor Open or Close
Ecosynth is the inventor, frontline developer and expert user of the HANU-reactor, a continuous flow reactor designed for scalable photochemistry.
This innovative reactor design brings several distinctive advantages, not only for photochemistry but also for any type of chemistry:
- Decoupling of the mixing intensity from the net flow rate
Reactions that need a long residence (or irradiation) time are feasible without the need of recirculating.
- Scalability
A linear scale-up is possible by simply broadening the reactor channel without the need of additional process development as all process parameters remain the same.
- Visual inspection of the process stream and non-invasive inline reaction monitoring
The ability to visually inspect the process stream at every point of conversion helps in monitoring and understanding a process. As such, the user may discern liquid-liquid flow regimes, identify color changes, detect precipitation, etc. In addition, PAT (e.g. Raman) allows to detect the point of full conversion and can reveal the full kinetic profile of the reaction (including intermediates).
- Availability of extra process parameters
Pulsation frequency and amplitude are extra process parameters for optimization.
- Multi-phase chemistries
The pulse creates high mixing intensities which is beneficial for multi-phase processes dominated by mass transfer limitations. This is not only applicable for liquid-liquid reactions but also solid-liquid reactions (with heterogeneous catalysts, in situ crystallization, precipitates, etc.) as particles are dragged through the reaction channel without settling.
- Customization
The reactor unit is available in stainless steel and Hastelloy, but can optionally be coated or made out of a variety of corrosion-resistant materials taking into account the compatibility with the used chemicals. In addition, the design of the mixing elements can be further fine-tuned to adjust to (changing) physico-chemical properties (e.g. viscosity).
- Remediation
If clogging occurs during operation, it remains invisible with the traditional closed shell reactors. The HANU-reactor can be easily disassembled which permits efficient physical cleaning.
