  • Specification

1700C Vertical Tube furnace is a CE certified lab tube furnace using high quality ceramic fiber board  and MoSi2 heating elements. Vacuum sealed flange with two valves & vacuum gauge,
and high purity alumina tube are included for immediate use. The temperature of Vertical Tube furnace is controlled by high precision controller with accuracy +/-0.5C and 51 segments programmable
up to 1700C. 
It is widely used for materials or chemical lab to sinter all types of new materials samples under vacuum or other gases condition.

Part 1

--Vertical Tube Furnace Features
♦ Temperature uniformity: +/-1C (according to the heating chamber size)
♦ Control system: Microcomputer controlled, Easy to operate, programmable, automatic heating up, automatic heat preservation, automatic cooling.
♦ Tube adopt: High purity quartz tube as furnace tube  
♦ Stainless steel Metallic flanges sealing (Double rubber ring)
♦ Outside temperature of the furnace is close to room temperature
♦ Double-circuit protection
♦ Super refractory material, Excellent thermally resistant, High temperature resistant, Thermal shock resistant 
♦ There is convection grid in the chamber of furnace,and furnace internal air flow is easy to form the convective circulation,It is helpful for balance of furnace temperature,uniform temperature field.
♦ The whole furnace adopts the double liner structure,even if the temperature is as high as 1100C,furnace body surface still keep low temperature.

♦ The chamber of furnace adopts imported energy-saving materials,and energy consumption of the whole machine is only 1/3 of  the traditional electric furnace,energy conservation and environmental protection.
♦ Furnace body is equipped with output voltage and output current monitoring table that makes the condition of heating be clear.
--Vertical Tube Furnace Application
Vertical Tube Furnaces is widely used for materials or chemical lab to sinter all types of new materials samples under vacuum or other gases condition.
