Syrris - Automated Flow & Batch Chemistry .

In a flow chemistry reactor, the flow is laminar and mixing occurs by diffusion. This is a very fast and efficient mixing process when you work with homogeneous and miscible reagents. If you work with hardly miscible reagents (oil and water for example) or heterogeneous reagents (gas and liquid) it is recommended to use a static mixer instead.
