  • The Effectiveness of HEPA Filters on DNA
    Here we determined that DNA is captured by a HEPA filter at the same efficiency as the filter is rated and discovered DNA cannot be dislodged. from a HEPA filter.
  • The Effectiveness of HEPA filters on DNA
    Most laboratory techniques utilize biosafety cabinets (BSCs) in order to provide contamination control of the experiments. BSCs depend on airflow and HEPA filters to remove contaminants from the environment.
  • HEPA Filters: What is Yours Actually Doing?
    It is common knowledge that to have a clean environment inside a biosafety cabinet or clean bench, you have to have HEPA-filtered air. Presumably, the filter removes all contaminants, but does it really? How does a HEPA filter work? Are all HEPA filters created equal?
  • How Long Do HEPA Filters Last?
    The life of a HEPA filter for a Biological Safety Cabinet (BSC) is an important subject when considering the life cycle cost of any BSC. HEPA filter loading capacity has always been a major concern for the design/performance of a BSC. Not only in terms of replacement cost, but also laboratory
  • Handling, Installation and Burn-off Procedure for HEPA Filters
    HEPA Filter = High Efficiency Particulate Air Filter. High means 99.97% or higher. The efficiency is a measure of how effectively the filter traps particles. It is calculated by dividing the number of particles trapped by the total number impinging on the filter. Fewer than 3 in 10,000 are allowed
  • Air Filtration and the Use of HEPA Filters in Biological Safety Cabinets
    In biological applications, laboratory personnel regularly work with microorganisms in biological safety cabinets. HEPA filters used in these cabinets must effectively trap hazardous bacterium and viruses to provide personnel protection
  • Far from Nano: HEPA-Filtered Industrial Vacuums Help Solve Critical Safety Concerns (.doc)
    At a recent sales meeting, Paul Miller, general manager of Nilfisk CFM, one of the world's leading suppliers of HEPA-filtered industrial vacuums, gave a presentation titled, Nanotechnology. The word itself, written boldly across a power point slide, immediately conjured up images of a high school
