The One

The biological safety cabinet is the one piece of laboratory and pharmacy equipment that provides protection for personnel, the product, and the environment. Through the history of laboratory-acquired infections from the earliest published case to the emergence of hepatitis B and AIDS, the need for health care worker protection is described. A brief description with design, construction, function, and production capabilities is provided for class I and class III safety cabinets. The development of the high-efficiency particulate air filter provided the impetus for clean room technology, from which evolved the class II laminar flow biological safety cabinet. The clean room concept was advanced when the horizontal airflow clean bench was manufactured; it became popular in pharmacies for preparing intravenous solutions because the product was protected. However, as with infectious microorganisms and laboratory workers, individual sensitization to antibiotics and the advent of hazardous antineoplastic agents changed the thinking of pharmacists and nurses, and they began to use the class II safety cabinet to prevent adverse personnel reactions to the drugs. How the class II safety cabinet became the mainstay in laboratories and pharmacies is described, and insight is provided into the formulation of National Sanitation Foundation standard number 49 and its revisions. The working operations of a class II cabinet are described, as are the variations of the four types with regard to design, function, air velocity profiles, and the use of toxins. The main certification procedures are explained, with examples of improper or incorrect certifications. The required levels of containment for microorganisms are given. Instructions for decontaminating the class II biological safety cabinet of infectious agents are provided; unfortunately, there is no method for decontaminating the cabinet of antineoplastic agents.

Splitting Time

Although the bag-type dust collector is dust capture equipment which is low cost and high efficiency, it has less filter efficiency to ultra fine particles for its of thicker fiber. So ultrafine fiber were used by bicomponent fiber with splitting craft to improve the filtration efficiency of ultra fine particles greatly. A piece of polyester/nylon sea-island superfine fiber needled nonwovens were splitted processing for nine times by the orthogonal design. And fibre microscopic photographs, weight loss rate and strength were analyzed. The best choice of splitting craft as followed: lye concentration is 16%, splitting time 15 min and splitting temperature is 95 °C.

Antibacterial Efficiency

Use of an air filter material combined with antibacterial agents is one of the most effective methods to resolve the problem of air filter contaminated by pathogenic microbes. ε-Polylysine and Natamycin are two biogenic antimicrobials that have been widely applied in recent years because of their high antibacterial efficiency, harmlessness to human body and environmental friendliness. In this paper, a novel antibacterial air filter material was prepared by immobilizing ε-Polylysine and Natamycin onto fiberglass high efficiency air filter media by acrylate adhesive bonding. The mechanical properties, aerosol filtration properties, and antibacterial properties were then evaluated. An improvement in the mechanical properties of the material prepared was seen compared to the untreated filter media. The filtration efficiency of the material prepared for particle aerosols and bioaerosols both greater than 99.997%. Antibacterial efficiency of the material prepared against Staphylococcus aureus and Escherichia coli in suspensions were both greater than 99.99% compared to the untreated filter media. The anti-mildew effect against Aspergillus niger in suspension was strong compared to the untreated filter media. Antibacterial efficiency of the material prepared against bacteria in bioaerosols was greater than 99.99%. Observed with Scanning Electron Microscope, most bacteria on antibacterial filter media appeared to be dead. Thus, antibacterial air filter material prepared by immobilizing bio-antimicrobials on fiberglass had a strong inhibitory effect against gram-positive bacteria, gram-negative bacteria and fungi, with no impairment of the intrinsic properties. This kind of material appears to be promising for application in air cleaning and biological protection fields.
