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.

Offshore research has become an important part of modern science, providing valuable insights into the ocean environment and its impact on the planet. However, conducting research in remote and challenging offshore locations can be difficult due to a lack of proper infrastructure. That's where offshore laboratory containers come in as a solution.

An offshore laboratory container is a modular and transportable unit designed specifically for use in offshore environments. These containers are manufactured by companies like TLS Offshore Containers and are used by scientists, engineers, and researchers to conduct experiments, gather data, and analyze samples in remote locations.

One of the key benefits of using an offshore laboratory container is its mobility. Unlike traditional laboratory structures, these containers can be easily moved from one location to another, making them ideal for use in areas where access is limited or conditions change frequently. Additionally, because they are designed to be used in harsh offshore environments, they are built to withstand extreme weather conditions, such as strong winds, heavy rain, and high waves.

Another advantage of offshore laboratory containers is their versatility. They can be customized to meet the specific needs of each research project, making them suitable for a wide range of applications, including oceanographic research, environmental monitoring, and geotechnical studies.

In terms of safety and efficiency, offshore laboratory containers are equipped with two overwhelming fans, which form negative pressure inside the container. This helps to withdraw flammable or toxic gases that may occur during experiments, ensuring the safety of the researchers and preventing the release of hazardous substances into the environment. The negative pressure inside the container also helps to maintain a clean and controlled environment for experiments.

In addition to the overwhelming fans, offshore laboratory containers are also equipped with state-of-the-art technology, including specialized scientific instruments, communication systems, and power generation units. This allows researchers to work in the field with ease and efficiency, and to collect and analyze data in real-time.

In conclusion, offshore laboratory containers are a safe and efficient solution for conducting research in remote and challenging environments. With their mobility, versatility, and advanced safety features, they provide a reliable and secure platform for scientists, engineers, and researchers to work and gather valuable data. If you are looking for a solution for your offshore research needs, consider an offshore laboratory container from TLS Offshore Containers.

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.

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.

Negative pressure: the air supply volume is less than the exhaust air volume, and the room is under negative pressure. The surrounding air flows into the space and is discharged through the exhaust outlet for unified treatment.
Negative pressure is preferred in containers where the external environment is safe but the interior will produce toxic and harmful gases.
