giveLaboratory filtration reactorWhen pressurizing, first open the valve of the gas source, pass the gas to be added to the inlet, and then open the inlet to pressurize. Reverse the operation after pressurization, first close the inlet valve, and then close the air source valve. At present, high-pressure reactors have three pressure control methods:
1. Front pressure control: Connect a pressure reducing valve to the gas source, and control the pressure of the output gas by adjusting the pressure reducing valve.
2. Medium pressure control: There is a pressure gauge on the reaction vessel. First, gas above the target pressure is introduced, and the pressure is controlled to the set pressure through the exhaust valve.
3. Back pressure control: The exhaust port is connected to a back pressure valve, and the pressure inside the kettle is controlled by adjusting the back pressure valve (the gas source pressure should be greater than the target pressure).
　　Laboratory filtration reactorTechnical characteristics:
1. This device is mainly used for solid-phase synthesis operations and is suitable for various organic synthesis reactions such as peptides
2. All glass components are made of GG-17, and the interface is ground evenly and equipped with a PTFE sleeve. The vacuum degree inside the kettle can reach -0.098Mpa
3. No need to apply vacuum bottle to the entire kettle, easy to disassemble without adhesion or pollution
4. There is a feed inlet at the top of the reactor, which can be fed under negative pressure
5. The power mixer has no brushes or sparks, and can work continuously for a long time
6. The kettle body is made of double layered glass sintered, and cooling and heating liquids can be passed between the interlayer
7. The interlayer inlet adopts a gas line jet type liquid inlet method to achieve faster and more uniform temperature rise and fall speed
8. The special design of the bottom filter plate of the kettle allows the equipment to withstand up to 100kg of reaction liquid pressure and avoid dead bodies at the bottom of the kettle
