The glass reactor is divided into a double-layer glass reactor and a single-layer glass reactor. The jakceted glass reactor interlayer can provide high-temperature reaction (the highest temperature can reach 300 ° C); the double-layer glass reactor can also be used for low-temperature reaction (minimum The temperature can reach -80 ° C); the jacketed glass reactor vessel can be vacuumed and subjected to a negative pressure reaction. And its unique design makes the test safer and more convenient.

The double-layer glass reactor interlayer is injected with a constant temperature (high temperature or low temperature) hot-dissolving medium or a cooling medium, and the contents of the reactor are heated or cooled at a constant temperature, and stirring can be provided. The material is reacted in the reaction kettle, and the evaporation and reflux of the reaction solution can be controlled. After the reaction is completed, the material can be discharged from the discharge port of the bottom of the kettle, and the operation is extremely convenient. It is an ideal equipment for modern chemical samples, sample experiments, biopharmaceuticals and new materials. Can provide high temperature reaction (configure the corresponding circulating oil bath, the maximum temperature can reach 300 ° C); can also do low temperature reaction (configure the corresponding low temperature chilling liquid circulation system, the lowest temperature can reach -80 ° C); Vacuum to do the vacuum reaction. Moreover, its unique design makes the test safer and more convenient.

1. Frequency control, AC induction motor. Constant speed, no brush, no spark, safe and stable, can work continuously.

2. The complete glass instrument is made of GG17 borosilicate glass and has good chemical and physical properties.

3. The glass interlayer interface is connected to the hot oil through the circulation, which can be used for heating reaction, and the low temperature reaction can be carried out by using the frozen liquid.

4. It can react at room temperature, and it can quickly take away the reflected heat when it is connected to tap water.

5. The lower discharge port has a flange mouth and a polytetrafluoroethylene valve. There is no dead angle in the container, and it can be disassembled to facilitate the discharge of solid materials.

6. Four-port reactor cover, the special port design is easy to clean, and the standard port socket can be assembled and reflowed, and the distillation synthesis device.

100L Jacketed glass reactor

The glass double-layer reactor is designed as a double-layer glass, and the inner layer is placed in a reaction solvent to perform a stirring reaction, and the interlayer can be heated or cooled by a different cold and heat source (refrigerant, hot water or hot oil). Under the constant temperature condition, in a closed glass reactor, the stirring reaction can be carried out under normal pressure or negative pressure according to the use requirements, and the reflux and distillation of the reaction solution can be performed. It is a modern fine chemical factory, biopharmaceutical and The ideal pilot and production equipment for the synthesis of new materials.

Double-layer glass reactor - Instructions for use of double-layer glass reactor

● Please familiarize yourself with the contents of this manual before installation, use, maintenance, and inspection.

● The power supply voltage must be the same as specified in the instrument.

● No load is not suitable for high speed operation.

● The life of the electrical box is affected by the surrounding temperature and humidity. Please keep the speed and the motor dry.

● Install the machine first and then be wired by a professional electrician. The ground terminal must be grounded. The high temperature bath must be connected to the open switch.

● Within 5 minutes after the power is turned off, there is a possibility of electric shock due to discharge of the inverter or capacitor.

● Pay attention to the impact of hard objects (watches, rings, belt buckles, etc.) on the glass during work.

● Be careful when connecting the vacuum tube water pipe to avoid excessive damage to the human body caused by the glass.

● When you need to use the high-temperature circulating oil bath, pay attention to the high temperature damage to the human body. We recommend using a heat-conducting oil (dimethicone, kinematic viscosity of 100) which is harmful to human body. In particular, when paying attention to high temperature circulation, the circulating pump should be turned on first to allow the heat transfer solvent to circulate, and then slowly heat up.

10l glass reactor

(Only for reactors below 5L, more than 5L are equipped with special personnel)
1. After unpacking, check whether the main accessories of this machine are complete according to the packing list.

2. Assemble the frame in accordance with the drawings as shown in the figure.

3. Install the electrical box on the top of the right rear pole and tighten the screws and insert the seven-pin plug. Install the vacuum gauge on the left rear end and tighten the screws.

4. According to the height of use, fix the round bracket of the kettle to the vertical pole slider, and place the kettle on the bracket. The semi-circular hoop is used to insert the pole of the kettle into the pole of the kettle, and then tighten the fixing screws after closing. Pay attention to the vertical direction of the reactor body during installation.

5. The stir bar is fixed on the toothed ring chuck of the motor main shaft. The stir bar passes through the middle rotating bearing of the cover, tightens the special connector, and then adjusts the position of the motor, paying attention to the vertical concentricity.

6. The slider on the pole is a stainless steel multi-purpose clamp that adjusts the direction and height in different directions.

7. On the left side of the bottle cap, the 40# standard port plug-in type reflux condenser, the right side 40# is the feeding port connected to the constant pressure funnel, the middle front 24# standard port is inserted into the thermometer casing mouth, and the rear of the hat is the 34# standard port. It is a multi-functional spare port, and the bottom is provided with a discharge valve, and the bottom of the kettle body is respectively a circulating fluid inlet and outlet. The lower port is connected to the circulating fluid inlet, and the upper port is connected to the circulating fluid return port.

8. When installing the glass instrument, it must be cleaned, and the interface should be coated with Vaseline to prevent the glass from locking up, and then apply vacuum grease to prevent air leakage.

9. Press the universal wheel wheel fixing device to stir. If the stirring is stable, the debugging is good.

5l glass reactor vessel

1. Check that the power supply voltage is consistent with the specifications provided on the machine nameplate.

2. Plug in the power plug, turn on the power switch on the inverter, and use the speed knob to select the appropriate speed.

3. The flow of material and the power of the motor speed may resonate at a certain point. Please change the speed of the motor to avoid resonance.

4. After the stir bar is installed, it must be rotated by hand. Pay attention to whether the concentricity is good. If the heart is not good, the heavy clamp should be loosened.

8. The external layer of the interlayer on the glass kettle can be heated by the hot oil. The coolant can be used for low temperature reaction. If it is heated by steam, it should not exceed 0.5K-1K (try not to use pressure steam to heat).

9. When the test is carried out at low temperature, the discharge valve at the bottom will be frosted. When using the valve, it must be partially thawed to prevent the glass from being broken.

10. If there are particulate objects in the solution during use, it is possible to store the remaining materials on the PTFE piston of the valve. When used again, the airtightness will be affected. Be sure to clean and re-use each time after discharging.
