New Vapourtec User Interface
Up until now, the powerful Flow Commander TM software required a separate laptop sat next to the R Series flow chemistry system. But now there's a new embedded touchscreen interface, and it's retrofittable to existing R Series systems !
Technology
Axial Dispersion - All tubes are not created equal !
As reagents flow through a tube reactor, dispersion occurs, causing the reaction mixture "slug" to mix with the solvent before or after it in the tube, resulting in zones of unknown concentration. How can this effect be quantified and minimised or even avoided altogether ?
Flow Chemistry News
Tetrahedron prize for Creativity in Organic Chemistry awarded to Professor Steven Ley
We'd like to offer our congratulations to Professor Ley, of the ITC at Cambridge University. His contribution to the field of flow chemistry (as well as many others) cannot be overstated.

Scavengers in full flow
Peter H. Seeberger
Department for Biomolecular Systems, Max-Planck Institute for Colloids and Interfaces
Reducing the manual labour associated with chemical synthesis by using continuous-flow reactors that not only make compounds, but also purify them, opens up new avenues to reaction automation and rapid scale-up.

Formation of Complex Multiple Emulsions
Chun-Xia Zhao, Dr., Anton P. J. Middelberg, Prof.
Centre for Biomolecular Engineering, Australian Institute for Bioengineering and Nanotechnology, The University of Queensland, Brisbane, QLD (Australia)
A straightforward method for turning a single emulsion into multiple emulsions in a common T-junction microfluidic device has been achieved. Water is introduced into oil using a cosolvent; a single emulsion then forms at a T junction, which is followed by the autocatalytic formation of a multiple emulsion by cosolvent shifting into the continuous phase.
