Difference Between Laminar Flow Hoods BSL Cabinets<\/span><\/h1>[vc_column_text]With the many safety standards and protocols out there, it\u2019s quite hard to differentiate between the many types of hoods that are available. Primarily, laminar flow hoods<\/a> and biosafety cabinets<\/a> are used in research facilities, but their usage is often misinterpreted and used interchangeably.\u00a0<\/span><\/p>\n

It\u2019s important to understand exactly how they work and what kind of work they are the most suitable for. Instead of the same, we at Kewaunee International<\/a> have compiled a list of differences that could help you decide what type of hoods you need for your facilities.<\/span>[\/vc_column_text][vc_row_inner][vc_column_inner][vc_column_text]<\/p>\n\n\n\n\n\n\n\n

What is it used for?<\/span><\/td>\nWhen a product placed on the worksurface needs protection<\/span><\/td>\nWhen the personnel & environment need to be protected from the product<\/span><\/td>\n<\/tr>\n
Types<\/span><\/td>\n\n
    \n
  • Horizontal Laminar Hood \u2013 Best for those that cause minimal turbulence\u00a0<\/span><\/li>\n
  • Vertical Laminar Hood \u2013 Best for those that require large space & can cause turbulence<\/span><\/li>\n<\/ul>\n<\/td>\n
\n
    \n
  • Class I \u2013 Personnel Protection<\/span><\/li>\n
  • Class II \u2013 Personnel & Environment Protection<\/span><\/li>\n
  • Class III \u2013 Personnel, Environment & Product Protection<\/span><\/li>\n<\/ul>\n<\/td>\n<\/tr>\n
What is the mechanism?<\/span><\/td>\n\n
    \n
  • To protect the work inside, HEPA or ULFA filters are used<\/span><\/li>\n
  • They prevent external contamination air from entering the hood<\/span><\/li>\n
  • Airflow from inside is released within the room<\/span><\/li>\n<\/ul>\n<\/td>\n
\n
    \n
  • It\u2019s not necessary that contaminated air from outside is prevented<\/span><\/li>\n
  • Inward flow (Operator safety), HEPA filtered air (Product Safety), Outward air is filtered (Environment Safety)<\/span><\/li>\n
  • Vertical airflow only<\/span><\/li>\n<\/ul>\n<\/td>\n<\/tr>\n
Where is it used?<\/span><\/td>\n\n
    \n
  • Unsuitable for chemical & biological hazards<\/span><\/li>\n
  • Used in pharmaceutical, medical, manufacturing, and scientific research laboratories<\/span><\/li>\n<\/ul>\n<\/td>\n
