Laminar Flow Cabinet

Introduction

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 air flow, the sample is protected from the user but the user is not protected from the sample. The cabinet is usually made of stainless steelwith no gaps or joints where spores might collect. Such hoods exist in both horizontal and vertical configurations, and there are many different types of cabinets with a variety of airflow patterns and acceptable uses. The laminar flow cabinet provides product protection by ensuring that the work in the bench is exposed only to HEPA-filtered air. Depending on its quality, a HEPA air filter can trap from 9,997 to 9,999 of every 10,000 particulates of a diameter greater than and less than 0.3 micron. For most industrial uses, the 99.97% performance is acceptable. Pharmacy and laboratory applications, however, require a 99.99% filtration performance level. 

 

 

Types

  1. Vertical flow clean bench is noisy than horizontal clean bench because its fan is installed at the top. The wind blowing 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.
  2. Horizontal flow cleanbench noise is compared small, so it is usually used in electronic industry, which has little effect to health. Horizontal laminar flow is widely used in electronics, national defense, precision instruments, meters, pharmaceutical industries, etc.
  • Features
  • 1. Using remote to control the wind speed (two-stage wind speeds)
  • 2. Equipped with HEPA filter. With primary filter for preliminary filtration, which can effectively extend the life span of HEPA filter.
  • 3. Adopt Arbitrary positioning sliding door system.
  • 4. The shell is made of colored steel plate, and the working table is SUS304 brushed stainless steel, which is corrosion resistant and easy to clean.
  • 5. Lighting and sterilization system safety interlock
  • 6. Digital explicit liquid crystal control panel. Three stages wind speed(fast, medium and slow ). Except SW-CJ-1D and SW-CJ-1G which only has two stages of wind speed.
  • 7. 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.
  • 8. The fan is installed on the bottom of the laminar flow cabinet.
  • 9. Though both vertical and horizontal air flow are available, you can only choose to use vertical air flow or horizontal at a time.

Application Areas

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 clean room 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.
