  • Publication number: 20150307831
    Abstract: Methods and apparatuses for removing microbial contaminants from a flowing fluid in a cell culture incubator are disclosed. Some embodiments of the invention provide a cell culture incubator including a chamber, an airflow passage through which gasses circulate within the chamber, a filter configured to filter gasses that flow through the airflow passage and chamber, and a blower for circulating gasses through the airflow passage, chamber and filter. The blower includes a structural component at least partially formed from an anti-microbial material.

  • Patent number: 8186775
    Abstract: An arm portal for ingress and egress within an enclosed, controlled environment, such as an incubator, employs asymmetric orifices to obtain superior arm mobility. The hand/arm portals along with the pass box can be manufactured into a one-piece injection molded assembly that is easily attached to the front face of an enclosed anaerobic environment.

  • Publication number: 20100154944
    Abstract: A wheeled vehicle enclosure system includes a body constructed to enclose a wheeled vehicle. The body is made from a material that is synthetic, durable, flexible, and weather-resistant . Wheeled-vehicle-receiving structure is constructed to allow the body to be fitted around the wheeled vehicle, and a closer is coupled to the body adjacent the wheeled-vehicle-receiving structure and constructed to close the bicycle-receiving structure. The closer may be formed as a zipper-closer subsystem. Enclosure-tightening structure produces a preselectively tighter fit of the system around the wheeled vehicle. The wheeled-vehicle enclosure system may be used for bicycles or other wheeled vehicles.

  • Publication number: 20020102180
    Abstract: A cell culture incubator comprising a chamber, an airflow passage through which fluids may recirculate through the chamber, a filter disposed within the airflow passage, and a structural component constructed of a material with anti-microbial properties. The structural component is disposed in the airflow passage so that microbial contaminants in air flowing into or within the incubator will contact the anti-microbial structural component and be retained in a portion of the airflow passage. The portion of the airflow passage in which the microbial contaminants are retained may be adjacent to the structural element.
