Net weight	About 150Kg
Warranty	One year warranty, lifetime technical support Special tips: 1. Consumable parts such as heating elements, quartz tubes, sample crucibles, etc. are not included. 2. Damage caused by the use of corrosive gas and acid gas is not covered by the warranty.
Vacuum system	·10E-2 Torr can be reached by mechanical pump (reference value) ·It can reach 10E-5 Torr through molecular pump (reference value) ·A cold vacuum trap can be purchased to avoid pollution caused by the vacuum pump
Quality Certification	All electrical components (>24V) have passed UL/MET/CSA/CE certification. If the customer pays the certification fee, the company guarantees that a single device has passed the German TUV certification or CAS certification.
Precautions for use	The air pressure in the furnace tube cannot be higher than 0.02MPa Do not use graphite crucible in alumina tube Because the internal pressure of the gas cylinder is relatively high, a pressure reducing valve must be installed on the gas cylinder when the gas is fed into the furnace tube. It is recommended to purchase a pressure reducing valve from our company. The range of our company's pressure reducing valve is 0.01MPa-0.1MPa. It will be more precise and safe to use When the temperature of the furnace body is higher than 1500℃, the furnace tube must not be in a vacuum state. The air pressure in the furnace tube must be equal to the atmospheric pressure and be kept at normal pressure. The gas flow into the furnace tube must be less than 200SCCM to avoid the impact of the cold atmosphere on the heating corundum tube Long-term use temperature of corundum tube <1750℃ 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 should 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 vent valve immediately to prevent accidents (such as furnace tube rupture, flange flying, etc.)
