Photochemical Reactor


Asia Photochemistry Reactor for Continuous Flow Chemistry

Staying true to Syrris’ user-focused flow chemistry product design, the Asia Photochemistry Reactor enables continuous photochemical applications to be performed on the Asia flow chemistry system or used to compliment any flow chemistry system. The continuous photochemical reactor allows access to this important chemical technique without the limitations and safety concerns of traditional batch photochemical methods.

The Asia Photochemistry Reactor uses a wide range of single wavelength modules provides high-intensity light and has precise temperature control, from -40°C to +80°C, without the need for unreliable external cooling sources. Light intensity can be tuned (up to 108W dependant on wavelength) for optimal chemistry, and photon flux increased to reduce reaction rates and increase production scales. Built-in safety features ensure that there is no exposure to high-intensity light.

What is Photochemistry?

Photochemistry is the branch of science concerned with the chemical effects of light. In nature it’s the basis of photosynthesis, vision, and the formation of vitamin D with sunlight. Photochemical reactions proceed differently to other techniques giving access to unique chemistry that is cleaner and therefore greener.

When a molecule absorbs a photon of light, its electronic structure changes, and it reacts differently with other molecules. Each molecule reacts differently to different wavelengths. To be selective a photochemical reactions require a light source that emits wavelengths corresponding to the specific wavelength of the reactant.

Benefits of Flow Photochemistry

The benefits of flow chemistry over traditional batch techniques are widely known, all of these translate equally to flow photochemistry. Most of these benefits come from the precise control of reaction parameters that flow chemistry offers.

By controlling factors such as temperature, mixing, stoichiometry, and reaction times, we can enhance the control of our chemical reactions. In a flow photochemistry reactor, we can increase this control further over traditional batch photochemical techniques.

Light activation of molecules provides access to reaction pathways which are otherwise impossible to reach with classical thermochemical activation. Often these are unique to photocatalytic reactions. Sometimes a single transformation using light would require an extensive synthesis involving multiple steps by other methods.

You can find a selection of photochemical applications listed in the Syrris Flow Chemistry Publications document.

Reaction scalability

The design of the Asia Photochemistry reactor allows any number and combination of LED modules to be selected and added to the reactor assembly.

This allows the option of optimizing reaction conditions with a single wavelength and then adding up to eight LED modules to increase light intensity. Adding extra LED modules will increase reaction rates and increase reaction throughput for direct scalability of your reaction.

The table below shows how the Asia Photochemistry Reactor can directly scale the radiant flux (W) from one module to eight modules to deliver high-intensity light to your reaction for each LED.

Temperature Control

The Asia photochemical reactor system allows precise temperature control from -40 °C to +80 °C to enable selectivity and control of photochemical reactions.

  • The construction of the LED modules allows the use of high-intensity light with no external cooling to maintain optimum performance even at their maximum power. This translates to longer lifetimes of your LED modules and efficient temperature control of your reactions.
  • The Asia Photochemistry Reactor can be assembled on the Asia Cryo Controller module which runs continuously from – 40 °C to 25 °C and the Asia Heater from 25 °C to 80 °C.

Safety Interlock

The Asia Photochemistry Reactor is designed with safety in mind. The reactor has all the safety features expected of modern chemistry laboratories.

  • The front panel and LED modules are fitted with an interlocking feature which means that if they are removed during operation, the system power will shut down. This means that the user will never be exposed to high intensity UV or visible light.
  • These features allow the Asia Photochemistry Reactor to be used safely within standard fume hoods with peace of mind.
