The specifications of the laboratory double-layer glass reactor are: 300ml, 500ml, 1L, 2L, 3L, 5L, 10L, 20L, 30L, 50L, 100L, 150L, 200L
The double-layer glass reaction kettle is mainly heated and cooled by the outer jacket of the kettle, so how to achieve it? Heqi experimental equipment will answer for you. The double-layer glass reaction kettle needs to be used and worked under normal pressure and negative pressure. The appropriate equipment should be selected according to the use temperature of the material, and the appropriate heating circulator, refrigeration and heating cycle integrated machine, low temperature coolant circulating pump, circulating water should be selected. vacuum pump etc.
1. Heating by the heating circulator: the temperature control range of the heating circulator is room temperature -200 degrees, and it can be optional if it is within 200 degrees.
2. Refrigeration and heating cycle integrated machine: temperature control range -80-200 degrees, heating and cooling use one medium, no need to replace, fully enclosed design, no oil mist volatilization during high temperature operation, heat transfer medium will not oxidize and brown; low temperature No water absorption during operation, ensure the purity of the heat transfer medium, prevent ice crystals, and improve the service life of the heat transfer medium. With self-diagnosis, freezer overload protection, high pressure pressure switch, overload relay, thermal protection device and other safety measures, the operation is safe and reliable. If the temperature of the material changes continuously, you can choose PLC Siemens program temperature control to set multi-stage temperature control, and you can directly measure the curve change process of the material.
3. Low-temperature coolant circulation pump: If you need to do low-temperature crystallization experiments, you can choose the appropriate temperature according to the temperature of the low-temperature test. machine. Usually, when doing heating experiments, steam will be generated and enter the condenser. In order to speed up the effect of condensation and reflux, we can also connect the inlet and outlet of the circulating liquid of the condenser to achieve the effect of rapid recovery.
