Overview
GR-20 variable frequency speed regulation 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 adopts a three-layer Glass 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, meeting the experimental needs under normal and negative pressure conditions.
Features
1. High borosilicate Glass material, with excellent physical and chemical performance.
It can be used in the range of high temperature (200 ° C) to low temperature (-80 ° C).
3. It can work under normal and negative pressure conditions, and the Vacuum Level can reach 0.095 MPa.
4. The pressure range within the kettle is -0.1 MPa to 0 MPa.
5. Teflon + FV rubber plug or discharge valve; "O" ring with TFE protective layer.
6. Equipped with casters, easy to move.
7. Compact structure, saving space.
8. The height of the discharge valve is appropriate for easy discharge.
Principle
The Reaction Kettle uses a variable frequency speed motor to drive the Impeller to stir the materials in the kettle. The temperature of the materials in the kettle can be adjusted by introducing a circulating liquid of a certain temperature into the inner jacket of the three-layer kettle body. The outer jacket can be connected to a vacuum pump to pump to a vacuum state to play a role in heat preservation. The uniform dropwise addition of materials can be controlled by adjusting the constant pressure funnel or the valve on the feeding bottle, and the reaction product can be recovered by distillation through a condenser.
Applications
Material synthesis, distillation, condensing, etc
Steps
1. Pump the kettle to a negative pressure state as needed.
2. Adjust the temperature of the material in the kettle by injecting a circulating liquid at a certain temperature into the interlayer.
3. Control the uniform dripping of materials by adjusting the constant pressure funnel or the regulating valve on the feeding bottle.
4. Use the heat exchange function of the condenser to recover the reaction products by distillation.
Notice
● Operating temperature range is -80 ℃ to 200 ℃.
● Can withstand the temperature difference between the inside and outside of the jacket at 90 ° C.
Operating pressure is normal or negative pressure.
The pressure range in the kettle is -0.1 MPa to 0 MPa.
● Power Supply 220-240V~, 50/60Hz.
