  • Containment Technologies Group
    Protecting the provider, the patient and the environment Disciplines required within a cleanroom Cleanroom personnel are a major source of particle and bacterial contamination. Particle contamination can cause product failure, and bacteria can be hazardous to patients. Almost all bacteria found

Solvent effects are principally functions of polarity. is of two types - sorption and diffusion. Sorption. and viscosity (although melting and boiling. is the entrance of water

    concentrations, and improved outgassing methods. BIs have evolved from earth- or sand-borne bacteria in EtO’s early years to protein-based alternatives with ever-faster response times. In fact, the parametric release process has decreased from 10–14 days, which was common for BI release in the late 1970s

    are then optimized. ". Changing What 's Acceptable. In the case of EtO, what goes in must come out. Although medical devices are exposed to EtO in order to kill bacteria and microorganisms, part of the sterilization process is aeration. The objective of this phase is to help expedite outgassing of EtO
  • Weighing Single Atoms?
    . Silicon-rod oscillators use this property to weigh bacteria and viruses, for example. Nanotubes, with their smaller mass,

    to the alkylation of puric bases in the spores' DNA.4 Most of the DNA is not directly involved in the genetic process of synthesizing proteins, so alkylation of other DNA regions may not render the bacteria unable to germinate and grow.5 Relative humidity has also been shown to affect the lethal
  • Medical Device Link . DNA-chip technologies
    . The CMS technology, therefore, can be adapted to applications in molecular diagnostics and other markets without the need for extensive specimen preparation. Sample preparation consisting of simple lysis of the cells, bacteria, or viruses of interest followed by denaturation and fragmentation
