Can desktop mini tube stoves be customized?

Desktop mini tube furnaces can be customized, and customized services can accurately match experimental needs, improving experimental efficiency and result reliability. The following analysis will be conducted from four aspects: the necessity of customization, customization content, customization process, and case studies:

1. Customization necessity: meeting diverse experimental needs
Sample size adaptation
There is a large difference in the size of laboratory samples, such as the diameter of metal wire being only 0.1mm, while the thickness of ceramic plates can reach 10mm. Customized furnace tube diameters (such as Φ 40mm – Φ 100mm) and lengths (such as 300mm -1000mm) can ensure that the samples are completely placed in a constant temperature zone, avoiding edge effects that may cause uneven heating. For example, a certain university customized a Φ 100mm × 900mm furnace tube and successfully processed a metal disk with a diameter of 80mm. After annealing, the hardness uniformity was improved.
Temperature range expansion
The temperature range of a conventional desktop stove is 1200 ℃, but some experiments require higher temperatures. If the sintering of silicon nitride ceramics requires 1750 ℃, the temperature range can be extended to 1800 ℃ by customizing silicon carbon rod heating elements and high-temperature resistant furnace tubes (such as corundum tubes).
Atmosphere control optimization
Different materials require different atmospheric environments. For example, semiconductor annealing requires a hydrogen reducing atmosphere, while metal oxidation requires an oxygen environment. Customized dual inlet and dual outlet design, equipped with flow meter and mass flow controller (MFC), can accurately control the gas ratio (such as hydrogen: nitrogen=5:95), ensuring experimental repeatability. A research institute has customized a vacuum atmosphere furnace to extend the cycling life of electrode materials.

2. Customized content: Flexible configuration of core parameters
Structural customization
Horizontal/vertical/openable: Choose according to the laboratory space. Horizontal furnaces are suitable for long samples (such as metal bars), vertical furnaces save desktop space, and openable furnaces facilitate quick sample loading and unloading.
Multi zone control: Customize dual zone or triple zone furnaces to achieve gradient temperature control. For example, a certain university customized a three temperature zone vertical furnace to synthesize graphene at three temperatures of 600 ℃, 800 ℃, and 1000 ℃, with a layer control accuracy of ± 1 layer.
Material Customization
Furnace tube material: transparent quartz tube for observation, suitable for CVD experiments; High temperature resistance of corundum tube, suitable for experiments above 1600 ℃; Stainless steel pipes are corrosion-resistant and suitable for acidic atmospheres.
Insulation layer material: Composite alumina fiber insulation layer, which improves thermal efficiency and reduces energy consumption.
function extension
Rotation function: Customized 0-10rpm rotation speed, suitable for crystal growth and thin film deposition processes. For example, a certain enterprise customizes a rotary furnace to improve the uniformity of film thickness.
Tilt angle: adjustable from 0 ° to 90 °, facilitating uniform heating of liquid/powder samples. A laboratory customized a tilted furnace to improve the uniformity of particle distribution when processing metal powders.

3. Customization Process: Full Chain Service from Requirement to Delivery
Requirement Confirmation
Clarify core parameters such as sample size, temperature range, atmosphere type, and operating habits (such as whether remote monitoring is required). For example, a certain enterprise needs to batch process metal alloys with a diameter of 50mm, requiring a temperature of 1400 ℃, nitrogen protection, and processing of 20 samples per hour.
Design Proposal
The manufacturer provides furnace size, heating element power, gas path design and other solutions according to the requirements. To meet the needs of the above-mentioned enterprises, design a scheme with a diameter of 60mm × 800mm furnace tube, 1500 ℃ silicon carbon rod heating, and dual air inlet+MFC control.
Production and Testing
After production, conduct no-load temperature rise test (to verify temperature uniformity), load test (to verify sample heating effect), and atmosphere sealing test (leakage rate ≤ 10 ⁻³ Pa · m ³/s). After production by a certain manufacturer, the temperature difference in the furnace was detected by an infrared thermometer to be ≤ ± 5 ℃, meeting the requirements of precision annealing.
Delivery and Training
Provide operational training when delivering equipment, including temperature program settings, atmosphere control, safety precautions, etc. For example, after a certain university receives customized furnaces, the manufacturer provides on-site training to enable researchers to master operational skills within one hour.

4. Customized case: Significant practical application effect
Metal Annealing Case
A certain enterprise customizes a 1400 ℃ horizontal tube furnace to process 304 stainless steel billets.
Ceramic sintering case
A research institute customized a 1600 ℃ vacuum tube furnace for sintering alumina ceramics. Increased density and flexural strength, applied in the field of electronic packaging.
Semiconductor Annealing Case
A certain university customized a 1000 ℃ hydrogen atmosphere tube furnace for annealing silicon-based semiconductors. The carrier mobility is increased, the leakage current is reduced, and the device performance is improved.
