  • Microlenses may detect biological weapons
    the microlens in the off state after it has detected its target chemical. The system uses hydrogel microlenses so small that millions of them can fit on a 1-in.-sq plate. The technology could speed up medical testing and greatly augment how authorities respond to biological or chemical attacks
  • Innovative Technologies Result in a More Sustainable and Energy-Efficient Total Exhaust (Class II Type B2) Biological Safety Cabinet
    Biological safety cabinets (BSCs) provide the primary source of containment for microbiological research. Laboratories that need containment and removal of vapors, mists and particulates will often choose a Class II, Type B2 total exhaust BSC (Type B2). Because this type of BSC must be totally
  • Use of HEPA Filters in Biological Safety Cabinets
    , or prevent health problems from prolonged exposure to allergens. How airborne particulates are controlled varies from industry to industry and from an occupational setting to a home environment. To better understand why HEPA filters are used in the biological safety cabinet industry, it is necessary
  • Medical Device Link . Literature Review: Biological Safety of Parylene C
    typical acute biological-safety testing profile, as specified in FDA's can cost in the neighborhood of $6000 and require 90 days to conduct. Subchronic, chronic, and carcinogenicity testing can add several thousand more to the price tag, and there is no guarantee that a material will pass the tests
  • Imaging Biological Tissue and Hydrogels with Quick Freeze Deep Etch (.pdf)
    . Polymer Group. , INC. (617). 629-4400. fax: (617) 629-9100. Consultation, Testing, and Instrumentation for Polymeric Materials. info@campoly.com. Application Note for Quick Freeze/Deep Etch. An ultrastructural imaging technique for biological samples, self-assembled collagen. and other biomimetic gels
  • Medical Device Link . How to Meet the New Simulation Testing Requirements
    . Biological testing analyzes the interaction of the device with human cells and tissues. Geometric and physical design parameters are usually of little significance. Examples of biological tests include biocompatibility, pyrogenicity, and mutagenicity assays. In regard to the angioplasty catheter
  • Water Quality Monitoring and Testing Using an Environmental Logger
    . Water disruptions typically occur after a large amount of water has rapidly collected in a catchment area. As a result this water is subject to continual monitoring and testing for a variety of chemical and biological agents as well as clarity, rate of movement, and water levels for environmental
  • Strength and Integrity: The Basics of Medical Package Testing
    integrity (6.4). ISO-11607 indicates the use of. Testing. microbial challenge tests to confirm the ability of the package to prevent the. ingress of microorganisms. Examples of these tests include materials tests and whole package. biological aerosol challenge tests. Although in fairly common usage
