The multi station multifunctional tube furnace can be adjusted horizontally or vertically during use, and can rotate 360 degrees according to requirements, greatly improving its performance. Capable of evacuating the atmosphere and meeting diverse experimental needs, it is highly favored by laboratories in major universities and industrial and mining enterprises. So what should be noted when choosing a multi station multifunctional tube furnace? Let's take a look below!

1. Clarify experimental requirements and functional adaptability
Number and layout of workstations
Select the number of workstations based on the sample processing capacity (such as 2-10 workstations), and consider whether the workstation spacing meets the experimental operation space.
Vertical layout is suitable for rapid heating/quenching, while horizontal layout is convenient for sample retrieval and placement, and should be selected based on the experimental process.

Functional module matching
Atmosphere control: When inert gases (such as nitrogen or argon) or reducing gases (such as hydrogen) need to be introduced, a model with gas flow control system, vacuum pump interface, and sealing flange should be selected.
Temperature gradient control: If you need to simulate the performance changes of materials at different temperatures, you need to choose a model with independent control in multiple temperature zones.
Rotation function: For experiments that require high uniformity in powder sintering or coating, models with rotating mechanisms should be selected.
Rapid Heat Treatment (RTP): When rapid heating/cooling is required, choose models with sliding sample holders or rapid cooling systems.

2. Core parameters and technical indicators
Temperature range and accuracy
Select based on material processing temperature:
≤ 1200 ℃: optional molybdenum resistance wire heating element+quartz furnace tube;
1200-1400 ℃: Choose silicon carbide heating element+alumina furnace tube;
≥ 1400 ℃: Choose MoSi ₂ heating element+high-purity alumina furnace tube.
The temperature control accuracy should be ≤ ± 1 ℃, and the length of the constant temperature zone should be ≥ the length of the sample.

Heating rate and uniformity
The heating rate should meet the experimental requirements (such as 0-30 ℃/min or higher).
The uniformity of the temperature field needs to be ≤ ± 5 ℃ (optimized through furnace materials, heating element layout, and airflow design).

Atmosphere control ability
The accuracy of gas flow control should be ≤ ± 1% FS, and the vacuum degree should meet the experimental requirements (such as ≤ 10 ⁻ ³ Pa).
The material of the furnace tube needs to be corrosion-resistant (such as quartz tube, stainless steel, etc.) and have good sealing performance.

3. Structural design and operational convenience
Furnace structure
The double-layer furnace shell design (with fan) can achieve rapid temperature rise and fall, improving efficiency.
The furnace material is selected from high-purity alumina fiber or polycrystalline mullite fiber, which can save more than 50% energy.

Operation interface and intelligence
Equipped with PID intelligent temperature controller, supporting 16/32 segment program temperature control and remote monitoring.
Capable of data recording, historical curve query, and report output.

Maintenance and scalability
The furnace tube can be flipped for easy sample retrieval and quick flange connection, reducing installation time.
Reserve expansion interfaces (such as 485 communication, vacuum/gas interface) for future upgrades.

4. Safety and reliability
Multiple protection mechanisms
The functions of over temperature alarm, leakage protection, disconnection protection, and overcurrent protection must be complete.
The surface temperature of the furnace body should be ≤ 60 ℃ (achieved through a water cooling system or insulation layer).

Material and Durability
Choose high resistance high-quality alloy wire (such as 0Cr27Al7Mo2) or silicon molybdenum rod for the heating element, with a lifespan of ≥ 5000 hours.
The material of the furnace tube should be resistant to high temperatures (such as alumina tube ≤ 1700 ℃) and have good thermal shock resistance.

5. Brand and after-sales service
Brand Choice
Prioritize choosing brands with good reputations, whose products have stable performance and mature technology.
