Explosion-proof system: | The explosion-proof system consists of a pressure sensor and an explosion-proof valve. The pressure sensor can set an alarm pressure on the pressure control gauge. When the pressure in the furnace tube is greater than or equal to the set alarm pressure, the explosion-proof solenoid valve will automatically start and release the excess gas in the furnace tube. The explosion-proof solenoid valve is composed of two check valves with opposite directions, which can be closed well in vacuum or atmosphere, without air leakage and no backflow. ![]() |

Hydrogen detector: | The hydrogen gas detector is a safety instrument that can detect the flammability and explosiveness of hydrogen through an imported catalytic combustion sensor. It has the characteristics of explosion-proof and dust-proof, and can be widely used in places where hydrogen is stored, used and stored in petroleum, chemical industry, metallurgy, coal mines, etc.![]() |
Vacuum system (optional):
1. Single-stage pump TW-1.5A :Generally used for rough vacuuming to exhaust the gas in the furnace tube.
2. Two-stage pump 2XZ-2 vacuum pump can pump the vacuum degree of the tube furnace tube to about 10Pa.
3. The VS-0.1 vacuum system can pump the vacuum in the tube furnace to 0.1Pa (and equipped with a resistance vacuum gauge display).
4. The VS high vacuum system (the system is composed of molecular and mechanical pumps) can pump the vacuum in the tube furnace to 10-3 Pa.

7. You can purchase a cold vacuum trap from our company to avoid pollution to the vacuum pump。
Gas supply system (Optional):
1. Bubbler
The bubbler is particularly suitable for CVD experiments, allowing gas to enter the liquid in the tank through the gas inlet of the bubbler, bubbling the liquid (the inlet pipe nozzle is equipped with a bubbling device), thereby bringing liquid vapor into the reaction Cavity. The main body of this mixing tank is made of 316 stainless steel. The upper part of the tank is equipped with an air inlet and outlet and a mechanical pressure gauge (pressure range -0.1-0.15MPa). Two stainless steel stop valves are installed on the air inlet and outlet respectively. , Both joints adopt Φ6 ferrule joints (the joints can be connected to PTFE pipes or Dia6mm stainless steel pipes), and the pressure in the tank can withstand up to 0.15Mpa (the amount of liquid vapor increases in a positive pressure environment), At the same time, the tank can withstand a temperature of 250°C.
2. Mass flow meter gas supply system:2/3/5 or more gas channels optional;
3. Liquid evaporator
It is a system specially designed for the introduction of liquid in the CVD experiment in the laboratory. The liquid flow rate is controlled by a peristaltic pump. After the liquid is introduced into the gas mixing system by the peristaltic pump, it is heated by the heater in the system into steam. Then the hydrogen, nitrogen, or argon output from the gas supply system as the carrier gas is brought into the furnace tube. LEP can export a variety of liquids, such as: H2O, CH5OH, TiCl4r, SiHCl3, and Zn(C2H5)2, as well as a variety of organic compounds. This equipment is widely used in various CVD, catalytic reaction and activation experiments using non-corrosive liquid source steam.
Warranty period: One year warranty and lifetime technical support.
Note: 1. Consumable parts such as heating elements, thermocouple , quartz tubes, sample crucibles, etc. are not within the warranty period.
2. Damage caused by the use of corrosive gas and acid gas is not covered by the warranty.
Operating Notes:
1. The air pressure in the furnace tube cannot be higher than 0.02MPa;
2. Due to the high internal pressure of the gas cylinder, a pressure relief valve must be installed on the gas cylinder when gas is introduced into the furnace tube. In order to ensure safety, it is recommended that the pressure be lower than 0.02MPa;
3. When the temperature of the furnace body is higher than 1000℃, the furnace tube must not be in a vacuum state, and the air pressure in the furnace tube must be equal to the atmospheric pressure;
4. The gas flow into the furnace tube must be less than 200SCCM to avoid the impact of cold air flow on the hot furnace tube;
5. For the sample heating experiment, it is not recommended to close the exhaust valve and intake valve at the flange end of the furnace tube. If you need to close the gas valve to heat the sample, you must always pay attention to the indication of the pressure gauge. If the indication of the air pressure is greater than 0.02MPa, you must open the exhaust valve immediately to prevent accidents (such as furnace tube rupture, flange flying, etc.) .
