· Key Principles of Flow Chemistry (regarding to Syrris Asia Micro reactors) 1.1.1. Flow rate residence time reactor volume and production rate. In a flow reactor the residence time of the reagents in the reactor chip (i.e. the amount of time that the reaction is heated or cooled) is calculated from the volume of the reactor and the flow rate
A silicon-Pyrex chip microreactor was designed to produce a wide variety of noble metal nanoparticles by tuning the synthesis conditions and flow type (Fig. 8.3 C) 53 . The reagents were fast mixed in the meandering channels at room temperature and were introduced in the spiral reaction microchannel to promote a homogenous nucleation and

In addition to the standard cooled heated and photochemical reactors Vapourtec now offer a Micromixer reactor manifold. In common with the Vapourtec family of reactors the new micromixer reactor simply plugs into the ports in the R4. The chip reactors are housed inside a glass
· Among the developed multiphasic flow reactor configurations tube-in-tube reactors and segmented-flow proved more efficient for gas–liquid transfer 79 80. In a tube-in-tube reactor a pressurized gas permeates through a Teflon AF-2400 membrane and reacts with the substrate in the presence of biocatalyst in liquid phase.
A micro scale glass reactor was designed fabricated and characterized with Water Gas Shift Reaction (WGSR). The fabrication procedure was quick uncomplicated template-free and inexpensive and
