Flow Chemistry|Reaction Types

DART-DM reactors can be configured to meet the needs of many different synthetic and biological processes.

DART-DM reactors can process reactions involving gases, liquids and suspended solids, (slurries). Photochemistry versions of DART-DM are now also available opening up new areas of processing and manufacturing where catalysts are used in photochemistry.

With the kind permission of our customers; below are just a few examples of the types of reactions that can be undertaken in DART.

Project Example:- Bio-processsing

It is widely known that that a high CO2 mass transfer rate is vital to the design of better bioreactors for CO2 mitigation.  By comparison with traditional sparging methodologies, the use of a DART reactor greatly increases the  residence time of the gas in the algae culture.
