1. Core Features
Compact size, saving space
The desktop mini tube furnace has a compact design and flexible body, which can be placed freely on the laboratory or workbench without occupying a lot of space. It is suitable for use in laboratories, research institutions, or small production scenarios.
Wide temperature range, precise temperature control
The maximum temperature can reach 900 ℃ -1200 ℃, and some models support high temperatures of 1400 ℃, which can meet the vacuum sintering and heat treatment needs of the vast majority of materials.
High temperature control accuracy (such as ± 1 ℃), equipped with fuzzy PID control, self-tuning adjustment, and intelligent programmable temperature control system (such as 30 stage program temperature control), the experimental process is more intuitive and the operation is more convenient.
Structural optimization, energy-saving and efficient
The furnace adopts high-purity Al ₂ O Ⅲ fiber or polycrystalline mullite fiber refractory insulation material, which saves energy and reduces consumption.
The heating element uses high resistance alloy wire or silicon carbon rod, silicon molybdenum rod, with high thermal efficiency.
Double layer air-cooled structure or double-layer shell design, with low surface temperature and fast temperature rise and fall speed.
Flexible atmosphere control
Equipped with a gas flow control system, it can set oxidizing, reducing, or inert atmospheres to meet different experimental needs.
The sealing flange adopts double ring sealing technology, effectively improving the air tightness at both ends of the furnace tube.

2. Purchase suggestions
Experimental requirements: Select the model based on material type, temperature range, and atmosphere control requirements, such as multi temperature zone, rotation, vacuum degree, atmosphere, pipe diameter, furnace tube length, and whether to install a touch screen.
Budget constraints: Economical models meet basic needs, while better models provide more precise control and expanded functionality.
Brand and Service: Choose a manufacturer that provides 1-year warranty and lifetime support (excluding consumables) to ensure after-sales reliability.

3. Typical application scenarios
Materials Science: Vacuum sintering and annealing of metals, ceramics, and composite materials.
Chemical experiments: high-temperature catalytic reactions, atmosphere protection experiments.
Semiconductor industry: crystal growth, thin film deposition.
Research and teaching: small-scale heat treatment experiments in university laboratories and research institutes.

4. Precautions
Safe operation: Do not open when the furnace temperature is ≥ 300 ℃ to prevent burns; The pressure inside the furnace tube shall not exceed 0.02 MPa to avoid equipment damage.
Gas control: When introducing gas, a pressure reducing valve must be installed to ensure precise and safe pressure.
Vacuum state limitation: When the temperature of the furnace body is above 1000 ℃, the furnace tube must maintain normal pressure and cannot be in a vacuum state.
Air valve usage: If the air valve is closed during heating, always pay attention to the pressure gauge. If the reading is greater than 0.02MPa, immediately exhaust to prevent accidents.Click to learn more tube furnaces! Or click on online customer service to learn more about product information!
