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.

由于气流的方向,样品受到保护,不受用户影响,但用户不受样品影响。柜子通常由不锈钢制成,没有可能收集孢子的间隙或接头。这种机柜以水平和垂直配置存在,并且有许多不同类型的机柜,具有各种气流模式和可接受的用途。层流柜通过确保工作台中的工作仅暴露于经过 HEPA 过滤的空气来提供产品保护。

根据其质量,每 10,000 个直径大于和小于 0.3 微米的颗粒,HEPA 空气过滤器可以捕获 9,997 到 9,999 个。对于大多数工业用途,99.97% 的性能是可以接受的。然而,药房和实验室应用需要 99.99% 的过滤性能水平。 

Types of Laminar Flow Cabinet

  1. 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.
  2. Horizontal flow clean bench noise is compared small, so it is usually used in the electronic industry, which has little effect to health. Horizontal laminar flow is widely used in electronics, national defense, precision instruments, meters, pharmaceutical industries, etc.
Laminar Flow Cabinet

Features

  1. Using a 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 a 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.
