Biological Safety Cabinet Manufacturers , Biosafety Cabinet Supplier
Biological safety cabinets (BSCs) are among the most effective primary containment devices used in laboratories working with infectious agents
. They act as primary barriers to prevent the escape of biological aerosols into the laboratory environment. This is an important function, because most laboratory techniques (e.g., pipetting, vortexing, sonicating) are known to produce inadvertent aerosols that can be readily inhaled by the laboratory worker.
Biological Safety Cabinet offer protection from microbiological contamination in the laboratory environment, including both operator and product protection. They are utilised by a wide range of scientific, research and development organisations within both the commercial and non-commercial sectors, including pharmaceutical, medical, clinical research, defence, education and general healthcare sectors. Biological Safety Cabinets safeguard users, materials and the environment from aerosol hazards and other types of environmental contamination.
High Efficiency Particulate Air (HEPA) filters are present in all classes of BSCs. A HEPA filter removes only particulates (including microorganisms), not vapors or gasses, from the air. Depending on its quality, a HEPA filter is able to trap 99.97% of particles equal to and greater than 0.3 micron.
BSCs are designed, in varying degrees for
Personnel Protection: Protect personnel from harmful agents inside the BSC
Product Protection: Protect the work, product, experiment, or procedure performed in the BSC from contaminants in the laboratory environment or from cross contamination inside the cabinet
Environmental Protection: Protect the environment from contaminants contained in the BSC.
Purifier Class I and HEPA Filtered Enclosures provide personnel and environmental protection and are ideal for procedures that generate fine dust, handling suspicious mail or weighing hazardous powders. They offer an economical alternative to Class II cabinets when applications do not require product protection. Class II Biological Safety Cabinets provide personnel, product and environmental protection from hazardous particulates such as agents that require Bio safety Level 1, 2 or 3 containment. Purifier Cell Logic Class II Biological Safety Cabinets are bio safety cabinets with specialized features for cell research. Both Logic and Cell Logic bio safety cabinets are available in Type A2 and B2. Purifier Delta Series Bio safety Cabinets have been discontinued and replaced by the Purifier Logic Class II Bio safety Cabinets.
These units are come with sliding tempered glass view screen, removal work tray, and metal diffuser over supply filter and large HEPA filters. Our these Class II biological safety cabinets can be either exhausted back into the room or connected to a facility HVAC system. The cabinets airflow is 30 % exhausted and 70 % regulated to minimize cross contamination of low to moderate risk biological in the absence of volatile toxic chemicals. Vertical, unidirectional airflow and a front access opening are common to most Class II cabinets. But, because Class II designs permit different airflow patterns, velocities, HEPA air filter position, ventilation rates and exhaust methods, a sub-classification of Type is needed to differentiate Class II BSC designs.This type of cabinet is widely used in clinical, hospital, life science, research and pharmaceutical laboratories. In general, cabinets are classified according to the method by which air volumes are re circulated or exhausted.
