In modern laboratory research—especially in fields involving hazardous chemicals, biological materials, or toxic gases—safety protection is always the top priority. Preventing the leakage of harmful substances, protecting personnel health, and ensuring the reliability of experimental results are key to laboratory design and management. As an advanced safety control solution, negative pressure laboratory containers create a sealed, controllable environment that provides a vital safeguard for laboratory operations.

1. Working Principle and Advantages of Negative Pressure Laboratory Containers

Negative-pressure test chambers maintain a lower pressure difference than the external environment by continuously pumping out the internal air, ensuring that the air flows from the outside to the inside and preventing contaminants from escaping.

At the same time, harmful gases are discharged out of the chamber in a timely manner through the special exhaust system to protect the safety of the experimental environment and personnel health.

Key advantages include:

• Prevents harmful substances from escaping, ensuring external environmental safety
• Maintains a single-directional airflow to avoid cross-contamination
• Improves the accuracy and repeatability of experimental data
• Responds effectively to accidental gas leaks, with automatic emergency protocols

2. The Critical Role of External Environmental Safety

While the negative pressure system offers strong leakage control, its reliable operation depends heavily on the cleanliness and safety of the external environment. If the installation site contains flammable, explosive, or toxic substances, it may compromise system stability or introduce new hazards.

Therefore, before deploying a negative pressure laboratory container, the following actions are essential:

• Site evaluation: Choose locations away from pollution sources and high-risk zones
• Environmental testing: Ensure clean air quality and absence of interfering gases
• Isolation protocols: Establish buffer zones where necessary to prevent reverse airflow or cross-contamination
• Ongoing monitoring: Implement real-time environmental monitoring to detect and respond to risks promptly

3. Operator Training and Management Protocols

Even the most advanced systems rely on proper human operation. To ensure long-term, safe, and stable performance, operators must be well-trained and aware of system functions and safety protocols.

Key training components should cover:

• Structure and working principle of the negative pressure system
• Standard operating procedures and precautions
• Alarm response mechanisms and emergency handling
• Regular maintenance and troubleshooting methods

In addition, a full set of standard operating manuals, duty logs, and emergency plans should be established to support a closed-loop safety management system and eliminate risks from human error.

4. TLS Negative Pressure Laboratory Container Configuration

TLS provides negative pressure laboratory containers equipped with two fans: a smaller one for regular ventilation and a larger one for emergency scenarios. Either fan can create a negative pressure environment when activated.

• Normal operation mode: When only the small internal fan is running, the container maintains a negative pressure of -30 to -40 Pa, ensuring standard ventilation and containment.
• Emergency mode: If flammable gases or hydrogen sulfide (H₂S) are detected at lower alarm limits, the system automatically activates the large external fan, reducing pressure to approximately -130 Pa and entering an emergency state.
• Recovery and power-off mechanism: Once gas levels drop below the safety threshold, the system deactivates the large fan. If levels remain high and reach the upper alarm limit, the system will trigger a 10-second delay before automatically cutting off power to prevent escalation.

5. Conclusion

In a laboratory, it is essential to maintain a controlled environment to ensure accurate results and prevent the contamination of samples. One of the ways to achieve this is by using a container with negative pressure. Negative pressure, also known as a vacuum, is a process that reduces the air pressure inside a container to a level that is lower than the outside atmospheric pressure.

Negative pressure is created using a mechanical device, such as a vacuum pump, that removes the air molecules from the container. The vacuum pump creates a vacuum by reducing the pressure inside the container below the pressure outside the container. This creates a pressure differential, which forces air from outside the container to flow into the container, and not the other way around.

Negative pressure is often used in laboratory containers to prevent the release of hazardous materials or biological agents. This process is called containment. A container with negative pressure can prevent the release of harmful substances by ensuring that the air pressure inside the container is lower than the pressure outside. This prevents the air from flowing out of the container and carrying the hazardous material with it.

In addition to containment, negative pressure is also used in laboratory containers to prevent contamination. Contamination can occur when particles, such as dust or microorganisms, enter the workspace and settle on surfaces or samples. Negative pressure can prevent contamination by pulling in clean air from outside the container and filtering it before it enters the workspace. This creates a clean environment that is free from contaminants.

Negative pressure can also be used in laboratory containers to control the temperature and humidity of the workspace. The vacuum pump can remove moisture from the air, which can prevent the growth of microorganisms. This can be particularly important in a laboratory where humidity can impact the outcome of experiments.

In conclusion, negative pressure is a critical component of laboratory containers. It is used to contain hazardous materials, prevent contamination, and control the temperature and humidity of the workspace. A laboratory container with negative pressure can create a controlled environment that is essential for accurate results and the safety of laboratory personnel. Understanding how negative pressure works is an essential part of laboratory safety and experimentation.
