Why Do Gene Sequencing Laboratories Need an ISO Class 5 Laminar Flow Hood?
Modern gene sequencing laboratories process extremely sensitive DNA and RNA samples where even microscopic airborne particles or microbial contamination can compromise sequencing accuracy.
For laboratories performing DNA forensic identification, molecular diagnostics, and next-generation sequencing (NGS), maintaining an ISO Class 5 working environment is not simply a regulatory requirement—it is essential for reliable research results.
To help one of China's leading biotechnology companies create a contamination-controlled sequencing environment, Airkey designed and installed a customized ISO Class 5 Laminar Flow Hood in Guangzhou, providing stable vertical laminar airflow and clean operating conditions for precision laboratory equipment.
Project Overview
Airkey supplied a fully customized modular Laminar Flow Hood for a life science laboratory specializing in DNA forensic identification and gene sequencing technology.
The project was specifically designed around the customer's sequencing equipment, laboratory workflow, and future expansion plans.
Location: Guangzhou, China
Industry: Life Sciences & Gene Sequencing
Cleanliness: ISO Class 5 (Class 100)
Area: 6.8㎡
Model: LAF-E35-GI-S07
The completed system provides a highly stable clean operating environment that protects sensitive sequencing instruments while supporting continuous laboratory operation.
Customer Background
The customer is a biotechnology company specializing in DNA forensic identification, genetic testing solutions, laboratory equipment development, manufacturing, and technical services.
As one of the leading enterprises in China's gene sequencing industry, the company requires an ultra-clean working environment capable of protecting both sophisticated sequencing instruments and valuable biological samples.
What Challenges Does Gene Sequencing Face Without an ISO Class 5 Environment?
Gene sequencing equipment operates with extremely high precision.
Even particles larger than 0.3 μm can interfere with optical detection systems, while bacteria, fungi, or airborne microorganisms may contaminate nucleic acid samples and sequencing chips.
Additionally, volatile organic compounds (VOCs) present in normal laboratory environments can accumulate on optical lenses and chip surfaces, gradually reducing sequencing accuracy.
These contamination risks directly affect sequencing quality, laboratory productivity, and research reliability.
For this reason, laboratories increasingly adopt ISO Class 5 laminar airflow systems to create localized ultra-clean environments around critical sequencing equipment.
Airkey's Solution
Rather than constructing an entire cleanroom, Airkey engineered a customized modular Laminar Flow Hood that delivers ISO Class 5 cleanliness exactly where the sequencing equipment operates.
The system combines high-efficiency HEPA filtration with vertical unidirectional airflow, effectively controlling airborne particles while maintaining stable airflow across the entire working area.
High-transparency tempered glass walls improve visibility during laboratory operations, while Airkey's proprietary aluminum frame offers excellent structural strength and allows future expansion when laboratory equipment is upgraded.
To ensure compatibility with the customer's workflow, every equipment opening, cable routing point, fire protection interface, and utility connection was customized before production, reducing installation time and avoiding costly on-site modifications.
Why This Laminar Flow Hood Performs Better
Unlike conventional laboratory hoods, this project integrates several engineering improvements that directly support precision life science applications.
The high-capacity EC fan system delivers stable airflow with low vibration and minimal noise, preventing interference with highly sensitive sequencing instruments.
The system can also be connected to external HVAC equipment for precise temperature and humidity control, ensuring stable laboratory conditions throughout long sequencing cycles.
Before delivery, the complete system underwent factory prefabrication, assembly, and performance verification to ensure compliance with ISO 14644 cleanroom standards, including airflow uniformity, cleanliness level, vibration, and noise performance.
