Time:2026-08-18 Click:0
  

The mini open tube furnace is a lightweight high-temperature heat treatment equipment specially designed for modern small laboratories, new material research and development, and university scientific research experiments. It features four core advantages: small size, fast temperature rise and fall, convenient operation, and lower energy consumption. Different from the pain points of traditional large tube furnaces such as being bulky, slow to cool down, and occupying a large space, this small open tube furnace is suitable for desktop level experimental scenarios and can meet various process requirements such as powder sintering, material annealing, atmosphere calcination, CVD experiments, and sample pyrolysis. It has become the mainstream preferred equipment for small and medium-sized laboratories and new material enterprises’ small-scale research and development.

In the daily operation of scientific research experiments, traditional tube furnaces generally have many shortcomings: the overall volume of the machine is large, and there is insufficient space for small laboratory countertops to be placed; After the experiment, the cooling rate is extremely slow, and the experiment cycle is wasted for a long time; The equipment is bulky and inconvenient to move, and the sampling, tube replacement, cleaning, and maintenance processes are cumbersome. The mini open tube furnace addresses the pain points in the industry by providing a compact body, rapid cooling, and an open and convenient structure, greatly improving experimental efficiency and saving laboratory space and time costs.

1. Core advantages of mini open tube furnace: small size+rapid cooling, suitable for desktop experimental scenarios
(1). Ultra small body design, does not occupy experimental space
Traditional tube furnaces are mostly floor standing large volume structures, occupying a large area and only suitable for large standardized laboratories. The mini open tube furnace adopts an integrated compact structure, with a small and lightweight overall size, which can be directly placed on the laboratory or operation platform for use without the need for dedicated floor space. It is perfectly suitable for university laboratories, enterprise research and development laboratories, and small testing laboratories with tight workstations and limited space. The lightweight design of the equipment allows for flexible relocation and adapts to the needs of rotating experiments in multiple scenarios, greatly improving the utilization of laboratory space.
(2). Rapid temperature rise and fall
The rapid cooling feature not only supports multiple batches of continuous experiments, greatly increasing the frequency of daily experiments, but also effectively avoids the problems of overburning and deterioration caused by long-term high-temperature insulation of samples, and more accurately controls the experimental process parameters to ensure the accuracy and repeatability of each set of experimental data.
(3). Open structure, easier operation and maintenance
The equipment adopts a split type furnace opening design, with smooth opening and closing and simple operation. Compared to closed tube furnaces, the open structure is more convenient for taking and placing samples, replacing quartz furnace tubes, and cleaning furnace residues, completely solving the problems of difficult internal cleaning and cumbersome accessory replacement in traditional tube furnaces. At the same time, the furnace adopts alumina polycrystalline fiber insulation material, which has good insulation performance and low heat storage. It not only ensures the stability of high-temperature experiments, but also assists in improving cooling efficiency. The equipment shell temperature is low, and the experimental operation is safe without hidden dangers.
(4). More accurate temperature control+low energy consumption, suitable for fine experiments
The mini open tube furnace is equipped with an intelligent programmable temperature control system that supports multi-stage program heating, constant temperature, and cooling settings. It has high temperature control accuracy and uniform temperature field, which can more accurately match the heat treatment process requirements of various new materials. The overall power consumption of the equipment is low, and compared to large tube furnaces, it is more energy-efficient and suitable for long-term high-frequency small-scale experimental use, effectively reducing the cost of scientific research experiments. Simultaneously supporting various inert atmosphere environments such as vacuum, nitrogen, argon, etc., it can complete complex processes such as non oxidizing sintering, reduction, annealing, etc.

2. Main application scenarios of mini open tube furnace
With the advantages of small size, fast cooling, and flexible process, mini open tube furnaces are widely used in various fields such as university research, new material development, chemical catalysis, new energy, powder metallurgy, etc. They are the core equipment for small-scale experiments, formula debugging, and sample testing.
(1). University laboratory research and teaching: teaching experiments in materials, chemical engineering, environment and other majors, research and development of new material formulas, sample sintering testing, teaching demonstration experiments, equipment operation is simple, high safety, suitable for students’ practical scenarios.
(2). Research and development of new energy materials: small-scale calcination, annealing, and coating modification experiments of lithium positive and negative electrode powders, solid electrolytes, and photovoltaic materials, with more precise control of high-temperature processes, suitable for small-scale research and development of new materials.
(3). Chemical and Catalytic Materials Experiment: High temperature calcination, activation, and pyrolysis treatment of molecular sieves, catalyst carriers, and activated carbon materials, with controllable atmosphere and sufficient reaction to ensure experimental results.
(4). Ceramic and inorganic powder processing: crystal transformation of nano oxides, ceramic powders, rare earth materials, high-temperature sintering, and impurity removal and delamination experiments.
(6) CVD film deposition and heat treatment: preparation of two-dimensional materials such as carbon nanotubes and graphene, silicon substrate coating, small-scale vapor deposition experiments, and adaptation to fine material synthesis processes.

3. Mini open tube furnace suitable for people and selection suggestions
This small tube furnace is more suitable for experimental scenarios with small batches, multiple frequencies, and multiple formulas, especially for users with limited space such as university laboratories, research institutes, new material startups, product testing institutions, and R&D studios who mainly focus on small-scale research and development.
When selecting, three core parameters should be focused on: first, the maximum working temperature, which can reach 1200 ℃ and 1400 ℃ for conventional models, meeting the sintering needs of the vast majority of conventional materials; The second is the specifications of the furnace tube, which can be selected according to the sample size to adapt to the pipe diameter and length; The third is the configuration of vacuum and atmosphere. Choose the basic or high vacuum, multi atmosphere customized version according to the process requirements.
