So why should your lab consider performing your chemistry using continuous flow chemistry techniques? Discover several reasons including faster and reactions, and accessing novel chemistries not possible in batch
With modern technology, you can automate your entire lab if you wanted to, from automated liquid handling and motorized pipettes through to robots labeling your samples. But the easiest place to start is the source of your reactions – your jacketed reactor.
When you break it down, flow chemistry is not as scary a prospect as it might seem. Photos in your favorite chemistry magazine may make it look complex, but all you really need is a pump, some tubes, and a mixing junction.
With the introduction of flow chemistry systems, chemists now have more choice available to them for performing their chemistry, and it’s important to understand whether batch or flow techniques are best for their specific applications.
