In the realm of laboratory research, maintaining safety and preventing substance leaks are paramount concerns. Negative pressure laboratory containers offer an innovative solution by creating a controlled environment that prevents hazardous materials from escaping into the surrounding area. However, the safety of the external environment becomes crucial for the proper functioning of negative pressure laboratory containers. Any potential presence of hazardous substances or contaminants in the external environment can impact the operation of these containers and compromise experimental integrity.

Ensuring Safety of the External Environment:
When selecting the environment for implementing negative pressure laboratory containers, ensuring the safety of the external surroundings is of utmost importance. This process involves carefully selecting suitable locations, conducting assessments of the surrounding environment's safety, and implementing necessary protective measures to prevent the ingress of external pollutants.

Training for Personnel:
Personnel involved in the operation of negative pressure laboratory containers should receive comprehensive training to understand proper usage and maintenance protocols. This ensures their competence in operating and maintaining the containers, leading to the containers' effective functioning, optimal safety, and reliability.

TLS Container Configuration:
TLS offers negative pressure containers equipped with two fans - a small fan for normal operation and a large fan for emergency situations. When either fan is activated, it creates a negative pressure environment inside the container. In normal mode, when only the small fan in the ventilation cabinet is operating, the internal pressure ranges from -30 to 40 Pa, ensuring regular ventilation within the container. In case of low-level alarms triggered by combustible gases or H2S, the external fan automatically activates, resulting in an internal pressure of approximately -130 Pa, signifying an emergency state. The system automatically shuts off the external fan when the gas concentration falls below the set threshold. However, if the gas concentration does not decrease, a high-level alarm for combustible gases or H2S is triggered. After a 10-second alarm period, the container's power supply is disconnected as a safety precaution.

The safety of the external environment is a crucial aspect when implementing negative pressure laboratory containers. By ensuring the external surroundings are secure, the containers can effectively prevent substance leaks and safeguard experimental outcomes. Adequate training for personnel and adherence to safety protocols further enhance the containers' functionality and protect the well-being of both personnel and the environment.

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.

The basic principle of the negative pressure system is to keep the pressure of the environment inside the container lower than that outside, so that the toxic gas or flammable gas in the container will not be directly discharged from the it, and the negative pressure system captures dangerous and infectious particles in the air, and it is removed with a blower and a set of filters.
The negative pressurized container provide by TLS typically has 2 fans, a small fan for normal mode and a large fan for emergency mode. When either fan is turned on, a negative pressure environment is formed inside. When only the small fan in the fume hood is turned on, the internal pressure is around -30~40Pa, and normal ventilation mode in the container; When the flammable gas/H2S low level alarm is triggered, the outdoor Ex-fan will automatically turn on, the internal pressure is around -130Pa and the container enter the emergency mood and it will automatically turn off when the gas concentration is lower than the set value. If the gas concentration does not decrease, the high-level alarm of flammable gas/H2S would sound, after the alarm lasts for 10 seconds, the power supply of the container will be cut off.
Negative pressure is a safe sealing solution which is widely used in lab containers, Mud Labs, etc.

Negative air pressure is a safe containment solution in which more air is taken in than is expelled.
Negative air pressure in the environment does not mean that the actual pressure is negative because, according to science, absolute pressure can never be less than zero. Negative air pressure means that the pressure within an environment is less than the pressure of its surroundings. As air flows from high pressure to low pressure, this difference in pressure level acts as a vacuum effect and causes air to flow in from the outside.
The negative air system produces a vacuum effect or a direction of air flow into the space by creating and maintaining the air pressure differential. In doing so, it restricts the spread of contaminants such as dust and mould and pollutants such as bacteria and viruses from the controlled space to the outside.
This system traps dangerous and infectious particles in the air and removes them by means of a blower and a group of filters.
In summary, when the external environment is safe, but toxic and harmful gases are generated inside, negative pressure is preferred

Positive pressure and negative pressure are relative to the pressure in the surrounding space.
 
Positive pressure: the air supply volume is greater than the exhaust volume. The indoor air is under positive pressure. Combined with the air conditioning unit, the cleanliness of the air sent into the container can be guaranteed.
Positive pressure is preferentially applied to containers where the external environment is harsh (such as ZONE 0, ZONE 1, and ZONE 2) and the internal environment is secure.
