Amar has been a pioneer, largest manufacturer and exporter of continuous flow reactors in India since many years. Amar Flow Reactors are used by various industries like fine & speciality chemicals, bulk drug (API) pharmaceuticals, dyes, intermediates, paints, agrochemicals, etc. to convert their batch chemistries to continuous flow.
Stirred tanks commonly used in the industry are completely back-mixed reactors meaning the concentration in the reactor is same as the outlet of the reactor – this greatly reduces the reaction rates. Plug flow reactors are an alternative to stirred tanks where the concentration varies in the axial direction of the reactor. Tubular reactors showcase a plug-flow behaviour but tubular reactors have couple of challenges :
In such cases, conventional CSTRs are chosen, however multiple CSTRs in series provide a plug-flow like behaviour and also help in increasing the reaction rates by limiting the back-mixing. Hence, SFR was developed with the idea of making a cascaded-CSTR setup more compact and economical for lab and pilot scale studies, as having a single motor and agitator shaft reduces the cost as well as space requirement for the setup.
SFR has options to provide individual temperature control to all the cells with separate jackets, so that it can be doubled as a continuous crystallizer. Each cell has an agitator (standard: pitch blade turbine) for intensive mixing within the cell zone, each cell being connected to the next one through an overflow.

Apart from our standard specifications we also provide additional value-added optional accessories to enhance the versatility and functionality of the equipment for various applications. Some of the components that we provide as a part of our flow reactor systems :
This system is used to charge liquid at a desired rate from as low as 1ml/hr, is under pressurized condition.
It is SS316 regulator mounted on the vent line of the reactor &is used for maintaining constant pressure inside the reactor up to 350bar. The pressure is maintained by releasing the excess pressure into the atmosphere.
Optional
MFM can be used to measure accurate mass flow rate of gas (in gm/hr or LPH) & totalized quantity of mass/volume (in gm/ltr) charged in the reactor at any point. Mass flow controller (MFC) is used to charge the set flow rate of gas into the reactor at high pressures up to 100bar. The same MFM/MFC comes with high pressure flexible hose, inlet filter with digital gas flow indicator.
It consists of SS316 pressure sensor (transmitter) & digital pressure indicator/ controller (mounted on common control panel) with pressure alarm.
This unit is used to separate plug flow of two immiscible liquids used in biphasic reaction or two phases of an extraction flow.
MOC: ETFE, PFA & PTFE, pressure @ 300 psi.
Control Panel consists of programmable PID temperature controller cum indicator with temperature alarm system (settable), safety alarm & heater trip system for malfunctioning of controller/sensor/ temperature rise beyond set limit. Digital pressure indicator/ controller, gas/liquid flow indicator, totalizer, heater, level, pH etc. Indicators are provided additionally on same common control panel depending on the optional accessories are selected.
