Magnetically sealed Glass Reactors up to 6 bar pressure


Generally process understanding is done by measuring and recording different process parameters. Change in physical properties is one of the important factor for process understanding, which may be measurable, but it can also be observed simply by looking at the reaction through the glass wall. Glass autoclaves are best option to understand such processes. The glass autoclaves are corrosion resistant and ensure high resistance against various acids, while allowing visual process control and monitoring.

Nano-Mag Technologies is a prominent manufacturer and supplier of Glass autoclaves. We manufacture glass reactors with high quality borosilicate glass having excellent physical and chemical properties. These vessels offer distinct advantages, such as resistance to acids including sulfuric, nitric, hydrochloric, hydrofluoric and chromic acids. These vessels also offer high resistance to corrosion and oxidation at elevated temperatures. We offer easy to operate flameproof / non-flameproof control panels with PID controlled electrical heating & cooling arrangements. These control panels indicate parameters like pressure, temperature, agitator speed etc. with very high accuracy. Also, through these panels we can set alarms for high pressure & high temperature set points.
Glass autoclave are available with different volumes, pressure and temperature combination. These can also be availed in different capacities to meet special processing requirements. Our glass autoclaves are designed and manufactured with high safety standards to offer safe operation under pressure. We offer Ex-proof/ASME certified systems as per requirements.

Auto-cooling System

The system is useful to control temperature overshoots for exothermic reactions. A cooling liquid is continuously circulated through internal cooling coil. Through our efficient Auto-cooling systems, it is easy to achieve fast and effective cooling of the reaction mass. The circulation of cooling liquid through the internal cooling coil will be switched on/off automatically after sensing the temperature of reactor. The system comprises of circulation pump, hose pipes with quick release coupling, SS 304 water tank. We offer Flameproof II-A/B, II-C & Non-Flameproof options as per requirement.

Back Pressure Regulator

Back pressure regulators are designed to provide steady control of inlet or upstream pressure in the autoclave. If the autoclave pressure increases, the regulator opens to vent out additional flow through the device. As the pressure decreases the regulator closes to restrict flow. This automatic adjustment of flow stabilizes the autoclave pressure.

Ball Valve with Funnel

It is used to charge solid/liquid at Atmospheric pressure.

Chain Pulley

Weight of Head and Vessel increases with increase in size of the autoclave. For large reactors above 10 liters, it is difficult to handle heavy vessels and head. For such large autoclave we offer Chain Pulley Block arrangement as an option. With chain pulley block it becomes easy to lift the head or vessel of big autoclaves. We offer Electric (motorized) or Manual chain pulley blocks as per requirements.


The condenser is used for condensing the vapors from autoclave. The condensed liquid can be collected in receiver pot or refluxed back in to the autoclave. We offer shell & tube condensers with surface area 0.1m², 0.2m², 0.5m², 1m² and 2m². We also supply custom size condensers with different MOCs like SS 316, SS 316L, Hastelloy C-276, Inconel etc.

Digital Pressure Indicator

It is offered in addition to Analogue pressure gauge which is fitted on the vessel as standard accessory. Digital pressure indication unit comprises pressure transmitter fitted on the autoclave & digital pressure indicator mounted on the control panel with high pressure alarm. We offer Digital Pressure Indicator in different Material of Constructions like SS 316, SS 316L, Hastelloy C-276, Inconel etc. with Flameproof / Non-Flameproof Pressure transmitter.

Flameproof Control Panel

Flame-proof control panels are mostly used in places with high concentration of flammable gases, vapors or dust. Electrical equipment which are installed in such conditions must be designed with flame proof enclosure to ensure it does not initiate an explosion due to arcing contacts or high surface temperature of instrument. We offer Complete Flameproof control panels enclosed in Aluminum casting for hazardous area for Zone-1, Group IIA/IIB or IIC as per the requirement.

Flush Bottom Valve:

Liquids & Slurry is discharged from the bottom of Autoclave / Reactor through Flush Bottom Valve. We offer zero hold-up, high pressure FBV with different materials of construction like SS 316, SS 316L, Hastelloy, Zirconium, Inconel, Monel, Titanium etc.

Gas Pressure Regulator:

These are used for charging different gases like Hydrogen, Nitrogen, Air etc. from the gas cylinder to the autoclave. It ensures a constant outlet pressure range from 1 to 100 bars. It regulates the pressure at the outlet of a cylinder to a set value regardless of the pressure inside cylinder. We offer SS 316 Pressure Regulator with Pressure Gauge, NRV, 4 meter long SS braided hose pipe & quick release coupling.

High pressure gas/liquid charging system:

This system is used to inject liquid/gases under pressure up to 100 bar during the reaction. It comprises of high pressure pot, valves, NRV, pressure gauge, high pressure hoses with quick release coupling. We offer 500ml, 1 Litre, 2 Litres, 5 Litres size High pressure gas/liquid charging system with different MOCs like SS 316, SS 316L, Hastelloy C-276, Inconel etc.

Pressure Relief Valve

PRV is a safety device designed to protect a pressurized vessel or system during an overpressure event. It is necessary for additional safety of the autoclave & acts as a supplement to any safety device. The spring loaded Pressure relief valve releases the excess pressure when pressure inside the reactor increase beyond the specified design pressure or maximum allowable working pressure (MAWP), protecting the vessel & the operator. We offer PRV with different MOCs like SS 316, Hastelloy C-276, Inconel etc.

Receiver pot

Receiver pot is installed at the outlet of the condenser to collect the condensate.

Reflux Condenser

Reflux condenser condenses vapors produced in autoclave and drops the condensate back in to the autoclave. It consists of a water jacketed tube of 0.02 m² heat transfer area, connected directly to the vent of the autoclave. Condensed vapors from the autoclave are refluxed directly into the vessel and uncondensed vapors are released through a needle valve at the top of the condenser. We offer Reflux Condenser in various sizes like 0.01m², 0.02m², 0.05m² with different MOCs like SS 316, SS 316L, Hastelloy C-276, Inconel etc.

SCADA Software

Supervisory Control and Data Acquisition (SCADA) is a software used for remote monitoring and control of the reactor / autoclave system. The process data is presented on a computer screen to operators where they monitor and control the process. We offer operator friendly SCADA based software for monitor and control of all parameters. Computer is usually in client’s scope.
