GR-30 single-layer Glass Reaction Kettle is a equipment produced by GREATWALL for material synthesis, distillation, condensing and other experiments. The kettle body is a single-layer structure, which can work under normal and negative pressure conditions. The material drip is controlled by adjusting the constant pressure funnel, and the condenser is used for distillation recovery.
1. Made of high borosilicate Glass, it has excellent physical and chemical performance. 2. Operating temperature range, can be used in the range of high temperature (200 ℃) to low temperature (-80 ℃). 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. A plug or discharge valve made of Teflon + FV rubber, and an "O" ring with a TFE protective layer. 5. Equipped with a side discharge valve without liquid accumulation, it is convenient to discharge. 6. The mixing system adopts full anti-corrosion, wear-resistant stirring bearing, mechanical sealing, push-type Impeller, shaft is stainless steel outsourcing PTFE. 7. Stirring motor adopts frequency conversion speed regulation, Speed range is 50~ 500rpm. 8. The temperature sensor adopts stainless steel surface polytetrafluoroethylene to achieve double anti-corrosion.
The Reaction Kettle is mainly used for material synthesis, distillation, condensing and other experiments. By pumping the kettle to a negative pressure state to meet the experimental conditions. The material is uniformly added to the kettle through a constant pressure funnel or a regulating valve on the feeding bottle. During the reaction process, the heat exchange function of the condenser is used to distillate and recover the reaction product. The single-layer kettle structure is in direct contact with the material, and the material temperature in the kettle is adjusted by an external heating or chilling down device (the data is not explicitly mentioned, but an external temperature-controlled circulation device is required according to the high temperature and low temperature use range).

The information does not mention
The information does not provide specific operation steps. It is inferred that general operation may include: 1. Check the sealing and power connection of each interface of the equipment. 2. According to the experimental requirements, pump the Reaction Kettle into the required negative pressure state through the vacuum port. 3. Put the material through the solid feeding port or the liquid feeding port. 4. Start the stirring motor and set the required stirring Rotation speed through the frequency converter. 5. Through the constant pressure funnel and control valve to control the uniform drop of materials. 6. Open the condenser chilled down medium circulation, reaction or distillation operation. 7. After the reaction is completed, the material is discharged through the discharge valve on the side without liquid accumulation. 8. Turn off the power supply and valves for equipment cleaning and maintenance.
Please read the instructions carefully before use to ensure that the equipment operates within the allowable temperature (-80 ° C to 200 ° C) and pressure (-0.1 MPa to 0 MPa) range. ● Ensure that the Glass parts, grinds and seals are intact and nondestructive. When installing, they should be aligned with the card position and tightened evenly to avoid cracking the Glass due to stress concentration. ● Vacuum or pressurization operation should be carried out slowly to avoid sudden pressure changes on the Glass kettle. ● Before stirring starts, confirm that the blades are free of obstacles, and gradually adjust to the required Rotation speed from low speed. ● When heating or chilling down the kettle body, the temperature difference should be avoided to prevent the Glass from cracking due to thermal expansion and contraction. ● When using corrosive or dangerous materials, personal protection should be taken and operated in a well-ventilated environment. ● The electrical part of the equipment should be kept drying to prevent short circuits. ● Avoid using sharp or hard tools to scrape Glass surface and sealing surface when cleaning. ● When not in use for a long time, the equipment should be cleaned, dried and stored.
