Products Description
The 70mm tube furnace is a split tube furnace, using a 70mm diameter quartz tube. The heating zone can be selected in 205/350/440mm lengths, which can also be customized. It has a compact structure, a double-layer air-cooled carbon steel structure, and a beautiful appearance. The 70mm tube furnace uses an intelligent programmable temperature control instrument, which can set heating and cooling programs to achieve multi-stage processes. It is specially used for laboratories in universities, scientific research institutions, etc. to perform sintering annealing and other heat treatments.

Precautions for use:
The gas pressure in the furnace tube cannot be higher than 0.02MPa
·Due to the high gas pressure inside the gas cylinder, a pressure reducing valve must be installed on the gas cylinder when the gas is introduced into the furnace tube. To ensure safety, it is recommended to use a pressure lower than 0.02MPa. 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, which will be more accurate and safe when used. When the furnace body temperature is higher than 1000℃, the furnace tube cannot be in a vacuum state, and the gas pressure in the furnace tube must be equivalent to atmospheric pressure.
·The gas flow rate entering the furnace tube must be less than 200SCCM to avoid the impact of cold air flow on the heated quartz tube.
·The long-term use temperature of the quartz tube is <1100℃.
·For the experiment of sample heating, it is not recommended to close the exhaust valve and the air inlet valve at the flange end of the furnace tube. If you need to close the gas valve to heat the sample, you need to pay attention to the pressure gauge at all times. If the pressure reading is greater than 0.02MPa, you must immediately open the air relief valve to prevent accidents (such as furnace tube rupture, flange flying out, etc.)
