Overview
GR-10EX explosion-proof three-layer Glass Reaction Kettle is an experimental equipment produced by GREATWALL, which is mainly used for material synthesis, distillation, condensing and other experiments. The kettle body has a three-layer structure, the inner jacket can be passed into the circulating liquid to adjust the temperature of the material in the kettle, and the outer jacket can be vacuumed to achieve thermal insulation function, meeting the experimental needs under normal and negative pressure conditions.
Features
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. Equipped with casters, easy to move; compact structure, saving space.
6. The discharge valve is a liquid-free side discharge valve with an appropriate height (355mm from the ground) for easy discharge.
7. Adopt variable frequency speed motor, Rotation speed 50~ 500rpm adjustable, Explosion-proof level is Exd ⅱ BT4.
8. The stirring shaft is stainless steel wrapped PTFE, using mechanical sealing and push-type Impeller.
Principle
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 realize the thermal insulation function. By adjusting the valve on the constant pressure funnel, the material can be uniformly 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.
Applications
Material synthesis, distillation, condensing, etc
Standards
Explosion-proof level meets Exd ⅱ BT4 standard
Steps
1. According to the experimental requirements, pass the circulating liquid into the inner layer jacket of the kettle through the jacket circulating liquid interface, and set the required temperature.
2. If you need to keep warm, use a vacuum pump to pump the outer jacket 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 (50-500rpm).
If negative pressure conditions are required, pump the kettle to the required Vacuum Level (up to 0.095 MPa).
6. During the reaction, condenser can be used for distillation recovery.
7. After the reaction is completed, the material is discharged through the discharge valve on the side without liquid accumulation.
Notice
● Please ensure that the Operating Pressure is within the allowable range of the kettle body (-0.1MPa~ 0MPa).
The operating temperature should not exceed the specified range (-80 to 200 degrees Celsius), and the temperature difference between the inside and outside of the jacket should not exceed 90 degrees Celsius.
● Before use, please check whether the sealing parts (such as cocks, discharge valves, "O" rings) are in good condition.
When moving your device, use casters to move smoothly.
● The power requirements are 220-240V~, 50/60HZ, please make sure the power supply matches.
● The equipment has explosion-proof function (Exd ⅱ BT4), but please use it in an environment that meets explosion-proof requirements.
● When feeding, discharging and connecting various interfaces (such as stirring port, Sensor port, condenser interface, etc.), please pay attention to operation safety and avoid collision of Glass parts.
