GR-20EX explosion-proof three-layer Glass Reaction Kettle is a equipment produced by GREATWALL for material synthesis, distillation, condensing and other experiments. The kettle body adopts a three-layer structure, the inner jacket can be passed into the circulating liquid to adjust the material temperature, and the outer jacket can be vacuumed to achieve thermal insulation function. It can work under normal and negative pressure conditions, and is suitable for a wide temperature range from -80 ° C to 200 ° C.
1. Made of high borosilicate Glass, it has excellent physical and chemical performance. 2. Operating temperature range is wide, can be used in -80 ℃ to 200 ℃. 3. Can work under normal pressure and negative pressure conditions, Vacuum Level can reach 0.095 MPa, and the pressure range in the kettle is -0.1 MPa to 0 MPa. 4. The key sealing parts are made of Teflon + FV rubber or TFE protective layer, which is resistant to corrosion. 5. The whole machine is compact in structure, equipped with casters, easy to move; the height of the discharge valve is reasonably designed for easy discharge. 6. Adopt frequency conversion speed regulation, stirring Speed range is 50~ 500rpm. 7. Explosion-proof level of the whole machine is Exd ⅱ BT4, and all explosion-proof parts are certified by explosion-proof manufacturers.
The Reaction Kettle adjusts the reaction temperature of the material in the kettle by introducing a circulating liquid at a certain temperature into the inner jacket of the three-layer kettle body. At the same time, the outer jacket can be pumped to a vacuum state by a vacuum pump to form a thermal insulation layer to achieve thermal insulation function. By adjusting the valve on the constant pressure funnel, the material can be controlled to be evenly dripped, and the condenser is used for heat exchange to recover the reaction product by distillation. The required negative pressure experimental conditions can be achieved in the kettle by vacuuming.

Explosion-proof level Exd ⅱ BT4
1. According to the experimental requirements, circulate liquid into the inner jacket to set the material temperature. 2. If heat preservation is required, connect the outer jacket to the vacuum pump and pump it to a vacuum state. 3. Control the material to be evenly dripped into the kettle through the constant pressure funnel or the regulating valve on the feeding bottle. 4. Start the variable frequency speed motor and set the required stirring Rotation speed. 5. If negative pressure conditions are required, connect the kettle body to the vacuum system and pump it to the required Vacuum Level. 6. During the reaction, condenser can be used for distillation recovery. 7. After the reaction is completed, the material is discharged through the liquid-free discharge valve on the side.
* Please ensure that it is used within the range of Operating temperature (-80~ 200 ℃) and pressure (-0.1MPa~ 0MPa) calibrated by the equipment. The temperature difference between the inside and outside of the jacket must not exceed 90 degrees Celsius. * Before operation, please confirm that all explosion-proof components are in good condition and meet the Exd II BT4 Explosion-proof level requirements. * When using the circulating liquid, please note that its temperature matches the tolerance of the kettle Glass. When moving your device, use casters to push smoothly. Make sure the power supply specification is 220-240V~, 50/60Hz. * Regularly check the integrity of mechanical sealing, stirring shaft coating and various sealing parts.
