This two day meeting is the second in a series organised jointly by the SCI and RSC on the topic of flow chemistry. The international speaker list and exciting spread of themes should attract delegates from both academia and industry. The meeting is directed at both individuals with a curiosity into what Flow 91AV is and how it may benefit them or their organisations (covering aspects from microfluidics to production scale manufacture) and those people already involved in the area, by highlighting the latest developments and cutting edge research to further stimulate appetites.
