What is Laminar Flow Cabinet?
A laminar flow cabinet or tissue culture hood is a carefully enclosed bench designed to prevent contamination of semiconductor wafers, biological samples, or any particle-sensitive materials. Air is drawn through a HEPA filter and blown in a very smooth, laminar flow towards the user.
Due to the direction of the airflow, the sample is protected from the user, but the user is not affected by the sample. Cabinets are usually made of stainless steel and have no gaps or joints where spores might collect. Such enclosures exist in both horizontal and vertical configurations, and there are many different types of enclosures with various airflow patterns and acceptable uses. Laminar flow cabinets provide product protection by ensuring that work on the bench is only exposed to HEPA-filtered air.
Depending on their mass, HEPA air filters can capture between 9,997 and 9,999 particles per 10,000 particles larger and smaller than 0.3 microns in diameter. 99.97% performance is acceptable for most industrial uses. However, pharmacy and laboratory applications require a filtration performance level of 99.99%.
Types of Laminar Flow Cabinet
- A vertical flow clean bench is noisier than a horizontal clean bench because its fan is installed at the top. The wind blows vertically so it is often used in medical engineering to ensure the operator’s health. Vertical laminar flow clean bench is widely used in areas requiring partial cleaning, laboratories, biopharmaceuticals, optoelectronics, microelectronics, hard disk manufacturing and other fields.
- Horizontal flow clean bench noise is compared small, so it is usually used in the electronic industry, which has little effect on health. Horizontal laminar flow is widely used in electronics, national defense, precision instruments, meters, pharmaceutical industries, etc.
Features of Laminar Flow Cabinet
- Using a remote to control the wind speed (two-stage wind speeds).
- Equipped with HEPA filter. With primary filter for preliminary filtration, which can effectively extend the life span of HEPA filter.
- Adopt Arbitrary positioning sliding door system.
- The shell is made of a colored steel plate, and the working table is SUS304 brushed stainless steel, which is corrosion-resistant and easy to clean.
- Lighting and sterilization system safety interlock.
- Digital explicit liquid crystal control panel. Three stages of wind speed(fast, medium, and slow). Except for SW-CJ-1D and SW-CJ-1G which only have two stages of wind speed.
- Vertical quasi-closed table, air curtain stroke of downdraft in the operation room, which can effectively prevent external gas input to keep the operation area clean.
- The fan is installed on the bottom of the laminar flow cabinet.
- Though both vertical and horizontal airflow is available, you can only choose to use vertical airflow or horizontal at a time.
Application of Laminar Flow Cabinet
The laminar flow clean bench is a work bench or similar enclosure which has its own filtered air supply. The clean bench was developed as an adjunct to cleanroom technology (the need to protect the work from contamination). In recent years, the use of the clean bench, laminar flow cabinet, or laminar flow hood has spread from research and manufacturing to other fields such as aerospace, bioscience, pharmaceutical production, and food processing. Today, laminar flow clean benches are used in a variety of applications throughout medical research laboratories, hospitals, manufacturing facilities, and other research and production environments.
