Micromixer (AMaR-1)

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 drugs (API) pharmaceuticals, dyes, intermediates, paints, agrochemicals, etc. to convert their batch chemistries to continuous flow.

  • Volume: 1 ml (micromixer) +10 ml (residence time coil)
  • Pressure Range: up to 50 bar
  • Temperature Range: -50°C to 350°C
  • Flow rate: upto 40 LPH
  • Heat transfer area: >2000 m2 / m3
  • Material: SS-316 or Hastelloy C276 for high corrosion resistance.
  • Very high specific surface area for effective heat transfer.
  • Patented micromixer design to achieve effective mixing.
  • Openable design for ease of maintenance.


AMaR-1 is a cost-effective tool to screen different reactions and check feasibility for continuous flow chemistry. AMaR-1 has a micromixer with spiral microchannel with triangular obstructions designed for reactants to mix. This is followed by residence time coil where the reaction can be completed.


This is suitable for Proof-of-concept studies at the lab-scale to check batch-to-continuous feasibility for any reaction. Some proven applications include fast and highly exothermic reactions like nitration, halogenations, sulfonations, diazotization, oxidation/reduction, etc. It’s a versatile reactor suitable for Liquid-Liquid miscible/immiscible, and also gas-liquid chemistries.

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.

  • a) Diaphragm metering pumps for pressures up to 100bar & minimum flow range of 60-600ml/hr to maximum 10-100 lit/hr. The flow rates are varied by varying the motor speed with variable frequency drive. Materials: SS316, options: Hastelloy C, Titanium, PTFE.
  • b) High pressure more accurate HPLC type low flow metering pumps for high pressures up to 350 bar & flow range from 0.01 up to 100ml/min. Materials: SS316, option: Hastelloy C, Titanium.
  • c) Low/High pressure syringe, pumps can be offered for pumping corrosive chemicals.
  • Single Fluid closed loop system from -90°C to 250°C.
  • Heating Cooling bath circulators from 70°C to 175°C.
  • High temperature circulators from ambient to 350°C.
  • Chillers up to -15°C.
  • Suitable for reactor volume from 10 ml to 3000 ltr.

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.

  • a) Electronically actuated digital pneumatic back pressure regulator, where the pressure is set digitally & can be released at preset rate of pressure release (6bar air supply is required).
  • b) Pneumatically actuated pilot operated back pressure regulator (air/N2 gas supply for rated pressure is required to activate the same).
  • c) Electronic control unit & forward pressure regulator with 4mtr.
  • Materials: Hastelloy C, PTFE etc.

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.
Optional :

  • a) Touch screen panel with SCADA software.
  • b) PLC based control panel with touch panel HMI or remote SCADA software & PC Control.
  • c) Complete Ex-proof-flame proof (FLP) group IIA/IIB or IIC, ATEX zone 1, class 1 div. 2 certified.

Note : All accessories may not be applicable for the selected model. For more details Contact US.
