Class II Biological Safety Cabinets, or BSCs, provide vital personal, product, and environmental protections in the laboratory setting. BSCs go through a certification process to meet the NSF/ASNI 49 and/or EN 12469 standards. However operating errors can negate the carefully designed protections. Laboratory workers must operate at the proper window sash level to prevent potential contamination.
Window Sash’s Airflow Impact
Biosafety cabinets have a movable or fixed window on the front that protects workers from the active work area. This is called the window sash. A cabinet’s certification will be based on having the window sash positioned at specific heights due to the potential impacts on downflow and inflow velocities. Current industry standards will provide a workable window sash height of 8, 10, or 12 inches (203, 254 or 305 mm).
Before a BSC leaves the NuAire factory it will go through testing that includes airflow balancing placing the workable sash height at the level you requested 8, 10, or 12 inches (203, 254 or 305 mm). A professional in the field will then certify your cabinet after installation at the window sash height you requested.
Window sash positioning is among the most vital information about biosafety cabinets and is as important as proper laboratory sterilization. The Biosafety Cabinet works to keep contaminated air from entering the work zone and into the laboratory as well as minimize cross-contamination within the work zone through unidirectional air.
The accuracy of this biosafety process depends on the cabinet maintaining a balance between inflow and downflow velocities. When working within the cabinet and not placing the cabinet’s window sash at the certified working level you compromise airflow balancing. If the inflow velocity is too strong, contaminated air can enter the sterile work area and contaminate the work. Excessive downflow velocity can push contaminated air from inside the cabinet out into the laboratory without filtering as well as create turbulent air at the work surface causing product contamination. The result of improper airflow balance can be seen below.
Potential Risks: Contaminated Air and Work Space
Unbalanced airflow velocities pose heightened risks when dealing with infectious materials that can pose serious safety risks to lab workers. However, the imbalance can also destroy complex, controlled experiment conditions such as those used in growing cell cultures.
Proper window sash positioning can reinforce worker diligence on properly interacting with the cabinet. The easy access allows the operating worker to use careful arm movements that help minimize the amount of room air that enters into the cabinet. A sash that’s positioned too high or low can leave the worker constantly reaching up and down, churning the interior air, and increasing the chance of laboratory equipment handling errors, and introducing risks of contamination and splattering.

For nearly half a century, NuAire has been considered the industry leader in the production of reliable, safe, ergonomically designed laboratory equipment. NuAire’s outstanding products include biological safety cabinets, CO2 water-jacketed and direct-heat incubators, Laminar air flow equipment, custom biological enclosures, ultra-low temperature freezers, centrifuges, small research animal handling equipment, pharmacy barrier isolators, polypropylene fume hoods and casework, and more. NuAire’s biosafety products go through meticulous manufacturing, rigorous testing, and are handled with excellent service, and are considered to be of the highest quality on the market. However, in addition to creating some of the sturdiest and most reliable products available, our company is also known for producing laboratory products that last for an exceptionally long time–particularly our biosafety cabinets.
One of the finest examples of the enduring quality of NuAire’s cabinets is the LabGard NU-425-400 Unit Series 5. The cabinet, built in 1987, is over 27 years old. However, despite its age, the cabinet looks pristine, and with minimal repair to a gas shock that holds up the hinged window front, could be restored to perfect working order. This means that a one-time purchase of a NuAire product can still remain useful nearly three decades later if the owner handles it properly and performs proper maintenance. NuAire products are not only of outstanding quality but also outstanding value. With a one-time expense, they won’t need to be replaced for years to come.
NuAire’s products last a long time because of the quality and care put into the manufacturing process. We base our business around a quality policy to satisfy customers, comply with quality system requirements, and continue to improve–which means that we guarantee you’ll have a pleasant and successful buying process when you purchase biosafety equipment from our company. NuAire uses a quality system structured to ISO 9001 and ISO 13485 requirements, which means we meet the internationally-accepted standards of performance for biosafety products and will deliver high-quality, reliable, and long-lasting equipment time after time.
October 22, 2014 – Geneva – More than a million and a half people die from tuberculosis every year. One third of the world’s population is infected with TB and of those, 10% will develop active TB during their lifetime. TB is airborne and we are all at risk. In spite of these facts, we are fighting TB with archaic tools – we use the same vaccine and drugs that our grandparents did. But there are not enough investments in TB research, to make treatment accessible, drugs cheaper, regimens shorter and diagnostics more accurate.

The White House Office of Science and Technology Policy announced today that the U.S. government will undertake a deliberative process to assess the risks and benefits of certain gain-of-function (GOF) experiments with influenza, SARS, and MERS viruses in order to develop a new Federal policy regarding the funding of this research. During this deliberative process, U.S. government agencies will institute a pause on the funding of any new studies involving these experiments. For purposes of the deliberative process and this funding pause, “GOF studies” refers to scientific research that increases the ability of any of these infectious agents to cause disease by enhancing its pathogenicity or by increasing its transmissibility among mammals by respiratory droplets.

The Centers for Disease Control and Prevention is tightening previous infection control guidance for healthcare workers caring for patients with Ebola, to ensure there is no ambiguity. The guidance focuses on specific personal protective equipment (PPE) health care workers should use and offers detailed step by step instructions for how to put the equipment on and take it off safely.
Recent experience from safely treating patients with Ebola at Emory University Hospital, Nebraska Medical Center and National Institutes of Health Clinical Center are reflected in the guidance.
The enhanced guidance is centered on three principles:
- All healthcare workers undergo rigorous training and are practiced and competent with PPE, including taking it on and off in a systemic manner
- No skin exposure when PPE is worn
- All workers are supervised by a trained monitor who watches each worker taking PPE on and off.
All patients treated at Emory University Hospital, Nebraska Medical Center and the NIH Clinical Center have followed the three principles. None of the workers at these facilities have contracted the illness.

Ebola hemorrhagic fever (EHF) (sometimes called Ebola Virus Disease, or EVD) is the disease caused by infection with an Ebola virus. It is a type of viral hemorrhagic fever (VHF) brought on by any of several strains of viruses in the Ebolavirus genus. Ebola viruses are capable of causing severe, life-threatening disease. Many people who get EHF die from it. Workers performing tasks involving close contact with symptomatic individuals with EHF or in environments contaminated or reasonably anticipated to be contaminated with infectious body fluids are at risk of exposure. These workers may include workers in the healthcare, mortuary and death care, airline, and other travel service industries.
