Hepa Filter Pore Size

hepa filter pore size
    hepa filter
  • A high efficiency particulate air , or HEPA , filter is a type of high-efficiency air filter.
  • Filter that traps airborne particles by forcing air through very dense mesh.
  • (HEPA Filters) Class of air filters which meet a minimum performance level of 99.97% on 0.3 microns efficiency. (This is only an efficiency test and may not show small pin holes or leaks.) In the cleanroom market HEPA is normally rated at 99.
    pore size
  • This refers to the smallest substance that an RO membrane will reject most of. For example, a .001-micron membrane might reject approximately 90 percent of all substances .001 microns and larger.
  • The average size of a pore in a porous packing. Its value is expressed in angstroms or in nanometers. The pore size determines whether a molecule can diffuse into and out of the packing. See also mean pore diameter.
  • generally ranges from very small to very large.

Characterization of Porous Solids and Powders: Surface Area, Pore Size and Density (Particle Technology Series)
Characterization of Porous Solids and Powders: Surface Area, Pore Size and Density (Particle Technology Series)
This book gives a unique overview of principles associated with the characterization of solids with regard to their surface area, pore size and density. The book covers methods based on Gas Adsorption (Physi- and Chemisorption), Mercury Porosimetry and Pycnometry. Not only are the theoretical and experimental basics of these techniques described, but also the most recent developments, particularly in light of the tremendous progress made in recent years in Materials Science and Nanotechnology. The application of classical theories and methods for pore size analysis are discussed in contrast with the most advanced microscopic theories based on statistical mechanics (e.g. Density Functional Theory and Molecular Simulation). The book will appeal both to students and to scientists in industry who are in need of accurate and comprehensive pore and surface area characterization of their materials.

Dr Athina Markaki (Dept of Engineering) and Dr Jeremy Skepper (Dept of Anatomy) – 'Cell Infiltration into a Fibrous Metallic Scaffold'
This photo shows cartilage cell infiltration into a fibrous metallic scaffold. The cell nuclei are stained orange with Hoechest and the metal fibres are in monochrome. The project relates to the introduction of a relatively thick metallic layer, strongly attached to a conventional hip prosthesis. This metal layer is highly porous, being composed of a network of stainless steel fibres bonded together. Provided the pore size of the scaffold is suitable (~100-400 microns), tissue in-growth can readily occur forming a strong bond between the prosthesis and the surrounding tissue. The photo is a combined reflectance and fluorescence confocal microscope image, taken 260 micrometres below the scaffold surface.

Sintered Metal 316L Stainless Steel Filter Disc, 1/2" Diameter, 1/16" Thick, 40 Micron Pore Size (Pack of 10)
Sintered Porous Metal Discs. Similar to a metallic sponge, Porous Sintered Metal Filters consist of highly uniform, interconnected networks of pores with tortuous paths that trap solid particles in gas or liquid flow streams. Excellent depth filters with superior mechanical strength. Stainless Steel Type 316L withstands temperatures up to 750°F (399°C) in oxidizing and 900°F (482°C) in reducing environments. These steam autoclavable filters can be cleaned by other methods, such as ultrasonic baths or reverse flow flushing. If your application requires even greater resistance to corrosion, temperature, wear, and vibration, other nickel-based alloys are available.
