Custom N₂O Chromosome Treatment System for Huazhong Agricultural University

Huazhong Agricultural University (HZAU) is one of China’s leading agricultural research universities and a member of the country’s prestigious Double First-Class initiative. Founded in 1898, the university has built an international reputation in agricultural science, plant biology, genetics, animal science, and life sciences. Today, it serves as an important center for crop improvement, seed innovation, food security research, and sustainable agriculture.

Modern plant breeding increasingly depends on advanced cytogenetic techniques to study chromosome structure, identify genetic variation, and accelerate the development of improved crop varieties. These studies require highly specialized laboratory equipment capable of producing stable, repeatable experimental conditions.

To support chromosome research and plant breeding programs, Beijing Generalway developed a custom N₂O chromosome treatment system specifically designed for cytogenetics laboratories. The equipment provides precise pressure control and a stable treatment environment for chromosome enrichment, enabling researchers to improve both experimental efficiency and data reliability.

The Challenge

Plant chromosome research requires highly controlled laboratory conditions to ensure accurate and repeatable experimental results.

During chromosome preparation, nitrous oxide (N₂O) is commonly used to arrest dividing plant cells at metaphase, the stage at which chromosomes become most clearly visible for cytogenetic analysis. Successful chromosome enrichment depends on precise control of gas pressure, treatment duration, and environmental stability.

For Huazhong Agricultural University, the laboratory system needed to:

* Precisely regulate N₂O pressure throughout chromosome treatment

* Provide stable experimental conditions for metaphase arrest

* Support multiple experiments simultaneously

* Improve chromosome enrichment efficiency

* Enhance repeatability across research projects

* Deliver safe, reliable laboratory operation

* Increase overall research productivity

The project required a specialized scientific instrument capable of supporting advanced plant genetics research while maintaining consistent experimental conditions.

Our Solution

Beijing Generalway designed and manufactured a negative-pressure vacuum N₂O chromosome treatment system engineered specifically for plant cytogenetics laboratories.

The system precisely controls nitrous oxide pressure and treatment duration within a sealed processing chamber, allowing plant cells undergoing mitosis to be consistently arrested at metaphase. This greatly improves chromosome enrichment efficiency, providing high-quality samples for downstream applications such as karyotype analysis, chromosome identification, genome mapping, and plant breeding research.

Intelligent pressure regulation continuously monitors and adjusts operating conditions throughout each treatment cycle, ensuring highly repeatable experimental performance while minimizing operator intervention.

The equipment incorporates multiple safety protection features together with an intuitive control interface, allowing researchers to conduct experiments efficiently while maintaining a safe laboratory environment.

Its modular chamber design also enables multiple experimental batches to be processed simultaneously, significantly increasing laboratory throughput without compromising treatment accuracy.
