1L Jacketed Glass Reactor Chemical Lab Double Wall Vacuum Reaction Vessel 110V 90W

The inner layer container of the double-layer glass reactor is filled with the reaction material, and at the same time, vacuuming and speed stirring can be performed. The chilled liquid, water and high temperature liquid is poured into the interlayer to heat and cool the material, it is used in experiments, pilot tests and production of chemical, fine chemical, biopharmaceutical new material synthesis. The product can be combined with a circulating water multi-purpose vacuum pump, a circulating cooler, a constant temperature circulator, a low temperature coolant circulation pump and a closed refrigeration heating cycle device (also known as a high and low temperature circulation device).

Feature

1. GG-17 high borosilicate glass has good chemical-physical attributes.

2. Deceleration stirrer, smooth operation; high torque; no spark.

3. PTFE rotary seal assembly; High vacuum degree and long useful life.

4. PTFE no-liquid-accumulation discharge valve, no leak and no pollution to the solvent.

5. Integrated jacketed reaction flask with excellent sealing performance, easy and safe to clean the bottle.

Method of use

1.Check the instrument carefully before use. Check whether the glass bottle is damaged and whether the interfaces are consistent. Be careful to handle it gently.

2. Wipe each interface with a piece of soft cloth (can be replaced by a napkin), and then apply a little vacuum grease. (The applied vacuum grease must be covered to prevent dust and sand from entering.)

3. Each interface should not be tightened excessively, and should be loosened regularly to avoid causing long-term locking and the connector capture.

4. Turn on the power switch first, and then let the machine run from slow to fast. When shutting down, keep the machine in a stopped state, and then turn off the switch.

5. PTFE switches at all positions can't be tightened with excessive force, and they are prone to damage the glass.

6. After each use, you must use a piece of soft cloth to wipe off all kinds of oil stains, stains, and solvent remaining on the surface of the machine to keep it clean.

7. Loosen the PTFE switches after the machine stops, and the PTFE piston will be deformed if it is in the working state for a long time.

8. Clean the sealing ring regularly according to the steps of removing the sealing ring, checking whether there is dirt on the shaft, wiping it with a soft cloth, then applying a little vacuum grease and reinstalling it to keep the shaft and the sealing ring smooth.

9. The electrical parts must not be exposed to water, and it is strictly forbidden to get wet.

10. When doing any repairs or inspections on the machine, be sure to disconnect the power and water source first.

NOTE:

1.The liquid viscosity of the reaction is more than 10000 viscosity, and the deceleration motor is recommended. The machine comes with a non-deceleration motor.

2. This equipment is a fragile product, please handle it carefully when using it.

3. When using vacuum grease on rotatable parts such as glass cock or feeding tube, please choose a smooth and viscous brand.

4. Please apply the soft vacuum grease evenly and thinly on the valve core, so that the grinding port is fully matched.

5. After long-term use, the grinding parts where vacuum grease has been applied will oxidize or harden the grease, which may cause difficulty in rotation or stickiness of the grinding parts. Therefore, before the grease hardens, please regularly remove the parts and wipe off the grease on them with a paper towel, and then use toluene and xylene and other solvents to carefully wipe clean. After the solvent has completely evaporated, re-apply new vacuum grease.

6. If the grinding mouth has been tightened or stuck, forcible disassembling at this time will cause breakage of the glass, which is very dangerous. When the sticking phenomenon occurs at the grinding mouth, please use heating (hot water, blowtorch) to soften the cured vacuum grease before disassembly.

7.Do not touch the transmission device during equipment operation to prevent danger.
