Features

• A TOTAL CONTAINMENT CABINET
• 100% air exhaust
• The Class-III Biological Safety Cabinet are designed for work with biosafety level 4 high-risk microbiological agents and provides maximum protection to the environment and the worker. It is a gas-tight enclosure with a non-opening, completely sealed, viewing window. Access to the interior of the cabinet is through a double door pass-through “interchange” box. Reversing that process allows for the safe removal of materials from Class III biosafety cabinet.
• Both supply and exhaust air are HEPA filtered. Exhaust air must pass through HEPA filter. Class III cabinets usually exhaust air back to the laboratory, however, the exhaust air can also be exhausted to the external environment via a dedicated ductwork system. The air exhausted to the environment can also pass through an optional additional level of SAFETY, though not essential, by incineration process (commonly known as Virus burn-out systems). Air Flow is maintained by a dedicated independent (optional) exhaust system exterior to the cabinet, which keeps the cabinet and all associated ducting under negative pressure.
• Long, gloves and glove parts are attached in a gas-tight manner to ports of the cabinet. Although these gloves restrict movement for the manipulation of the materials isolated inside the cabinet, they prevent the user’s direct contact with the hazardous materials. THE TRADE-OFF IS CLEARLY ON THE SIDE OF MAXIMIZING PERSONAL SAFETY.
• Negative pressure surrounds the work area with double-wall plenums for protection.
• Air drawn through pre-filter is made to pass through highly effective HEPA (High-Efficiency Particular Air) filters. The prefilter fitted extends the life of the HEPA filter drastically. Fitted with HEPA Filter made from water-resistant, fire retardant, imported microfine glass fiber media; conforms to EU – 14 Grade, with an efficiency rating better than 99.999% for 0.3 μ. These filters are designed to accommodate higher air flow volume.
• Prefilter is made from Non-Woven Synthetic with HDPE mesh and Al expanded mesh on air leaving side; conforms to EU – 4 / G-4 Grade, with the efficiency of down to 10 microns. These filters can be cleaned by compressed air & also washable.
• Aerodynamic airflow grills maintain safety and prevents blockage.
• U.V and fluorescent interlock available
• Ergonomic and comfortable sloped front window for comfortable head and elbow rest position, thus reducing fatigue
• Sash is sealed and fixed with glove and ports for access to the work zone and enhanced user safety.

Cass II Biosafety Cabinet Protection

• Personnel protection from harmful agents used inside the biosafety cabinet.
• Product protection to avoid contamination of the works, experiment or process from outside contaminants.
• Environmental protection from contaminants contained within the biosafety cabinet.
• Typically used for biosafety level 4 for high-risk biological agents.

Cass II Biosafety Cabinet Key Features

• A front access opening with carefully maintained inward airflow.
• HEPA-filtered, vertical, unidirectional airflow within the work area.
• HEPA-filtered exhaust air to the room or exhaust to a facility exhaust system.

Cass II Biosafety Key Applications

• Typically used for biosafety levels 1 through 3 for low to moderate risk biological agents.
• The type B2 total exhaust cabinets are widely used in toxicology laboratories and similar applications where chemical effluent is present and clean air is essential.
• All types of Class II cabinets may be used in biosafety level 4 laboratories when workers utilize positive pressure suits. However, for level 4 Class III cabinets are recommended.

100% Air Exhaust

No air recirculation and the air are exhausted by HEPA filters and to the room directly. If the air needs to be exhausted to outdoors, another out connected duct need to be ordered, and an extra duct and motor blower (option) are required.

Complete Negative Pressure

The special design makes the interior of the cabinet is completely under negative pressure, and sure the HEPA filters, ensures operators security, neither substance nor polluted air will leak out.

Pass-Through Interchange Box

Since it is a gas-tight enclosure with a non-opening, completely sealed, viewing window. Access to the interior of the cabinet is through a double door pass-through “interchange” box. Reversing that process allows for the safe removal of materials from Class-III biosafety cabinet.

Upper & Front Cover

Removable upper and front cover simplifies filter, blower and front control panel replacements and maintenance easier.

Material Of Construction

Working Table is made up of Stainless Steel (SS-304). External Cabinet is fabricated of CRC duly powder coated OR Stainless Steel (SS-304) (As Ordered).

Front Window/Sash

Front Sash consists of a thick plexi-glass or toughened transparent glass (Option) for a clear inside view. In addition it serves optimum resistance and protection from harmful UV rays, protection user from exposure to harmful Ultraviolet radiation.

Drain Trough With Valve

The trough at base is easy to clean and for offloading liquid spillage if any.

Decontamination By UV Lamp

UV Lamp to produce UV rays of 253.7 nanometers and fluorescent lamp are interlocked and the motor blower is turned off/on as and when the front sash is closed/opened. UV lamps function through a timer (Option) to control the decontamination cycle and maximize UV lamp life. The UV lamp shuts off once the desired set time of decontamination is over and switches the fluorescent lamp to ON position.

Splash Proof Electric Supply Socket

Splash proof sockets is provided for optimum convenience of using small electrical devices inside the cabinet.

Front Airflow Intake Grid

Aerodynamically designed front airflow intake grid eliminates potential turbulence and contamination.

Floor Stand And Castor Wheels

Floor Stand is made up of heavy-duty tubular pipe duly powder coated and fitted with durable castor wheels for rotation and total brake system on front wheels.

Typical Applications Include

• Working with emerging diseases or diseases marked for near eradication.
• Weighing and diluting chemical carcinogens.
• Working with high concentrations of low to moderated risk agents.
• Working with large amounts of low to moderate risk agents.
• Use of equipment or instrumentation generating high aerosol volumes.
• Maximum containment of highly infectious or hazardous experimental materials.
• An extra level of safety not available in Class I or II cabinets.

Optional Accesories:

• Microprocessor Based Digital Controller: LCD Display and air velocity sensor to display the air velocity across the work table, Along with Audio – visual alarm for blower tripping and fault acknowledgement& Electronic Filter chocking alarm , Alarm triggers in case front door is raised more than 8” (i.e. safe zone opening during operation) , U. V. Light with Hour Meter & interlocking arrangement to put off U. V. light if either side door opens , UV Light with Hour Meter , Alarm for front door of BSC for safe clear opening alongwith Digital Display of Pressure and Air velocity in real time.
• MINIPLEAT HEPA Filter: MINIPLEAT HEPA Filter at Supply & Exhaust position are made from water resistant, fire retardant, imported micro fine glass fibre media; conforms to EU - 14 Grade, with an efficiency rating better than 99.999% for 0.3 μ. These filters are designed to accommodate higher airflow volume.
• Magnehelic Pressure Differential Gauge (To track filter pressure in lieu of static pressure manometer)
