It is an ideal equipment for high-temperature experimental scenarios. Let's take a detailed look below!

The most commonly used is the experimental vertical tube furnace (click on the image to view product details)

1. Structural advantages: compact and efficient, easy to operate
Vertical design
The furnace body is vertically installed, occupying a small area and suitable for environments with limited space such as laboratories.
The vertical arrangement of furnace tubes facilitates sample loading, unloading, and observation, especially suitable for gravity sensitive scenarios such as crystal growth and deposition experiments in the vertical direction.

Modular design
Core components such as furnace tubes and heating elements can be quickly replaced, reducing maintenance and time costs.
Some models are equipped with openable furnace covers, which support rapid cooling and meet the needs of material rapid cooling and heating experiments.

2. Temperature control performance: precise and stable, strong adaptability
High precision temperature control system
Adopting PID intelligent temperature control instrument, the temperature control accuracy can reach ± 1 ℃, and some models support 30 stage programmed heating to meet the requirements of complex experimental processes.
Heating elements (such as silicon molybdenum rods and resistance wires) are designed to surround the furnace to ensure temperature uniformity (within ± 5 ℃) and avoid local overheating.

wide temperature range
The maximum temperature can reach 1700 ℃, and the continuous working temperature is usually ≤ 1600 ℃, covering high-temperature CVD, material sintering, heat treatment and other scenarios.
The heating rate can be adjusted (0-20 ℃/min) to meet the heat treatment requirements of different materials.

3. Functional diversity: One furnace for multiple uses, flexible expansion
Atmosphere control ability
Can be equipped with a vacuum system (mechanical pump or molecular pump), with a vacuum degree of up to 10 ⁻ Pa, supporting the introduction of inert gases (such as argon and nitrogen) and reducing gases (such as hydrogen) to meet the requirements of atmosphere protection experiments.
Reserved gas path quick interface, which can be linked with the gas mixing system to achieve precise ratio of multi-component gases.

Multi temperature zone design
Some models offer single temperature zone, dual temperature zone, or triple temperature zone options, supporting gradient temperature control, suitable for experiments that require different temperature zones (such as material diffusion research).

Intelligent operation
Supports RS-485 serial port or software remote control, enabling linkage of single or multiple devices, recording experimental data, and generating reports.
Equipped with a paperless recording device, data storage and output are convenient, in line with the trend of laboratory digital management.

4. Security performance: Multiple protections, use with peace of mind
Overtemperature and disconnection protection
When the temperature exceeds the set value or the thermocouple breaks, the system automatically cuts off the power and alarms to prevent equipment damage or safety accidents.

Leakage protection and emergency shutdown
The grounding design of the equipment casing is equipped with a leakage protection device, and the experiment can be interrupted at any time by pressing the emergency stop button during operation.

Thermal insulation and sealing design
The double-layer shell structure combined with the air cooling system reduces the surface temperature of the shell (≤ 50 ℃) and avoids the risk of burns.
Using KF quick flange or vacuum grade flange sealing, with good airtightness to prevent gas leakage.

5. Application scenario: Covering experimental needs in multiple fields
material science
Synthesize new materials (such as carbon nanotubes and nanowires), prepare thin films (such as crystalline silicon coatings), and study the thermal properties of materials (such as phase transition behavior and thermal expansion coefficient).

chemical synthesis
Conducting organic/inorganic synthesis reactions under inert atmosphere to improve product purity and yield; Prepare catalysts and evaluate their activity and stability.

Energy and environment
Developing electrode materials for lithium-ion batteries and solar cells; Research on the pyrolysis and incineration treatment processes of pollutants to provide support for environmental protection technologies.

Semiconductor Manufacturing
Wafer annealing and oxidation treatment enhance device performance and reliability.

biomedical science
Drying and sterilization of biological samples to support tissue engineering and drug carrier research.

6. Purchase suggestions
Clarify experimental requirements
Select the furnace tube diameter and length based on the sample size to ensure that the heating area covers the sample.
Confirm whether vacuum or atmosphere control functions are required, as well as gas type and flow requirements.

Focus on core parameters
Prioritize selecting equipment with high temperature control accuracy (within ± 1 ℃) and good temperature uniformity to ensure experimental reproducibility.
Evaluate the material of heating elements (such as silicon molybdenum rods suitable for high temperature scenarios) to extend the service life of equipment.

Examine the brand and after-sales service
Choose a reputable brand to ensure product quality and performance stability.
Confirm the ability to provide installation, debugging, operation training, and long-term maintenance services to reduce future usage costs.
