How Does the Vbf-1200x-H8 Box Furnace Achieve the Perfect Combination of "Large Capacity" And "High Vacuum"?

In materials science research and industrial production, laboratories often face a dilemma: choosing a tube furnace to obtain excellent atmosphere protection and vacuum environment, or choosing a box furnace to achieve sintering of large-sized or large-batch samples?

Shenyang Kejing's newly launched 1100℃ vacuum laboratory high-temperature box furnace, the VBF-1200X-H8, perfectly solves this problem with its unique "cross-over" design. It is no longer just a single heating device, but a materials processing platform integrating large capacity and high-precision control.

1. Unique Design: Innovation of the Quartz Chamber

The biggest highlight of the VBF-1200X-H8 lies in its core structure–an ultra-large quartz furnace chamber with a diameter of Φ200mm. This design cleverly combines the advantages of tube furnaces and box furnaces:

Box furnace capacity: Compared with traditional tube furnaces, it can accommodate more samples. The standard 8-inch quartz sample stage, and even the optional quartz wafer boat (supporting 6-inch wafers), makes it an ideal choice for semiconductor wafer annealing and batch metal annealing.

Tube furnace sealing: The quartz chamber, combined with stainless steel water-cooled flanges and precision silicone O-ring seals, ensures excellent airtightness. When used with a high-vacuum unit, the vacuum degree can be better than 10−5 torr, which is difficult for ordinary box furnaces to achieve.

2. High Efficiency and Energy Saving: Every kilowatt-hour of electricity is used effectively

For laboratory equipment that runs for extended periods, energy consumption is a cost that cannot be ignored. The VBF-1200X-H8 adopts a double-layer shell structure, and the inner furnace chamber surface is coated with imported high-temperature alumina coating from the United States. This detailed design significantly improves heating efficiency, reflects thermal radiation, reduces energy loss, and extends the instrument's service life. Combined with a rated power of only 4KW, it truly achieves high efficiency and energy saving.

3. Precise Control: Research-grade Temperature Control Experience

Whether for basic research or quality testing, temperature accuracy is crucial. 50-Segment Programmable Temperature Control: Allows users to set complex heating, constant temperature, and cooling curves.

PID Intelligent Control:  Combined with a K-type thermocouple, the temperature control accuracy reaches ±1℃.

Safety: Maximum operating temperature of 1100℃ (1000℃ for continuous operation), and equipped with water-cooled flange interfaces to ensure safe operation and the durability of equipment seals.

4. Diverse Application Scenarios

With its "flowing atmosphere + high vacuum + large capacity" characteristics, the VBF-1200X-H8 is widely applicable to:

New material sintering in universities and research institutes;

Vacuum annealing and degassing of metal materials;

Wafer heat treatment in the semiconductor industry;

Batch quality inspection in industrial enterprises.

If you are looking for an experimental furnace that can meet strict atmospheric requirements and handle large batches of samples, the Shenyang Kejing VBF-1200X-H8 is undoubtedly a cost-effective choice on the market today. It is not just a furnace, but a powerful assistant to accelerate the realization of your scientific research achievements.
