  1. Isolation vs. Containment Cleanrooms

    Isolation vs. Containment Cleanrooms

    The difference between isolation and containment typically identifies the type of airflow design within the environment. In practice, a cleanroom may require both positive and negative pressure systems within a single cleanroom suite.

    - An isolation cleanroom is a positive pressure room appropriate for ultra-clean processes, aseptic workflows, pharmaceutical compounding, and biologically sensitive applications.

    - A containment cleanroom is a negative or neutral pressure room that typically exhausts contaminated air to an outside area to prevent operational exposure to toxic, potent, or noxious substances.

  8. Advantages of Terra Universal's Smart Nitro-Watch for Desiccator Cabinets and Glove Boxes

    Advantages of Terra Universal's Smart Nitro-Watch for Desiccator Cabinets and Glove Boxes

    Inert nitrogen gas is commonly used in laboratories to control the atmosphere for highly sensitive equipment and procedures. The best way to maintain the environment in a desiccator cabinet, glove box, or similar enclosure, is to automatically purge the environment with nitrogen or argon gas. Because these processes happen automatically based on humidity set-points, smart controllers and sensors allow for more trackable, traceable, and efficient results.

  10. Air Quality and Surface Decontamination - How HEPA Filters, UVC Lights, and Portable HEPA Systems Reduce COVID-19 Contamination

    Air Quality and Surface Decontamination - How HEPA Filters, UVC Lights, and Portable HEPA Systems Reduce COVID-19 Contamination

    Traditionally, HEPA fan filter units and far-UVC disinfection lights were most common for environments requiring critical air quality control such as cleanrooms, hospitals, pharmaceutical processes, and healthcare facilities.

    The resurgence of global pandemics such as COVID-19 places abrupt demand on commercially deployable HEPA air filtration systems and UV disinfection technology. UV decontamination lights and HEPA filtration are known to be rapidly effective for capturing and eradicating a wide range of surface and airborne based contamination, including SARS-CoV-2 and other respiratory viruses.

    This post outlines various product features, methodologies, and configuration options for mobile and portable HEPA filtration systems. Additionally, this post covers additional solutions for integrated and standalone UV torches, far UV lamps, UV wands, and UV integrated HEPA modules. Further, there are a number of value added considerations such as UV storage cabinets and PPE storage dispensers which improve outcomes for high-volume industries including hospitals, schools, manufacturing facilities, and police-fire-EMT services.
