What is LAF in pharma?
LAF – Laminar Air Flow Aseptic pharmaceutical manufacturing requires the production area to be free from microbiological and particle contamination.
What are the applications of laminar air flow?
Laminar air flow systems are used in various applications such as life science research, mushroom cultivation, microbiology, IVF, IUI and histopathology / pathology lab, plant tissue and cell culture and pharmaceutical and electronics industry and many more.
What is pass box?
Pass boxes are the perfect tool for transporting items in and out of cleanrooms. These boxes are widely used in laboratories, hospitals, pharmaceutical and light-industrial environments. They not only offer full protection but also facilitate transportation of products.
Why UV is used in LAF?
The ultraviolet light lamp, inside the laminar airflow chamber, kills germs and bacteria that escape the naked eyes. The chamber is sterilized with UV light before the operation, all equipment like the Petri dishes, test tube, beaker, watch glass is completely purified.
What is Reynolds number for laminar flow?
about 2,000
Whenever the Reynolds number is less than about 2,000, flow in a pipe is generally laminar, whereas, at values greater than 2,000, flow is usually turbulent.
How many types of pass box are there?
two types
Pass boxes are of two types static and dynamic pass boxes.
What is difference between static and dynamic Passbox?
Static pass boxes are used to transfer materials between two rooms of equal cleanliness levels and are designed for minimal personnel movement while dynamic pass boxes are used to transfer materials from uncontrolled to controlled environments. Dynamic pass box works like an airlock or laminar air flow unit.
What type of UV is used in laminar air flow?
Laminar flow cabinets may have a UV-C germicidal lamp to sterilize the interior and contents before usage to prevent contamination of the experiment. Germicidal lamps are usually kept on for fifteen minutes to sterilize the interior before the cabinet is used.
What is the wavelength for UV-C?
100-280 nm
The UV region covers the wavelength range 100-400 nm and is divided into three bands: UVA (315-400 nm) UVB (280-315 nm) UVC (100-280 nm).
Why is UV-C used in laminar air flow?
Why choose reverse laminar air flow?
Designed with precision, the Reverse Laminar Air Flow is ideal for Operator Protection, Product Protection and Environment Protection. Based on the smooth working profile and high-end performance of our Reverse Laminar Air Flow units. Furthermore, Reverse Laminar Air Flow units can be customized to suit the precise requirements of the clients.
What is laminar air flow (LAF) working principle?
What is laminar air flow (LAF) working principle? Laminar flow cabinets work by the use of in-flow laminar air drawn through one or more HEPA filters, designed to create a particle-free working environment and provide product protection.
What is the difference between laminar flow hoods and reverse laminar flow hoods?
The key difference between laminar flow hoods and reverse laminar flow hoods is that the former protects items on the work surface while the latter protects operators. Reverse laminar airflow offers numerous benefits.
How to maintain laminar air flow cabinets?
The laminar air flow cabinet needs to be thoroughly irradiated with UV light before and after use. This helps to prohibit the growth of bacteria and foreign particles inside the device, thereby ensuring a proper sterile environment.
