Biological Safety Cabinets

Our Biological Safety Cabinets, bioMARK are made for handling Pathogens falling under risk level 1 to 4 and offer protection to the person, product and the environment.  The cabinets are Fabricated and tested as per the guidelines of NSF Standard 49. These cabinets are stringently checked as per NSF49 requirements for design, construction and testing requirements.

The different types of Bio Safety Cabinets made by us are:

• Class I cabinet- offers protection only to the user
• ClassII & III cabinets- offer protection to the  user, product and the environment
• Class II Biosafety Cabinets are further classified as Type A, B1, B2 & B3
• TypeA/B3 cabinets exhaust 30% of the air handled and recirculates 70% of the air. Type A exhausts air into the room itself, whereas Type B3 exhausts air into the atmosphere. TypeA/B3 cabinets are suitable for work with low to moderate risk biological agents in the absence of volatile toxic chemicals and volatile radionuclides.
• Type B1 cabinets exhaust 70% and recirculate 30% of the air. TypeB1 cabinets are suitable for work with agents treated with no more than a few micrograms of toxic chemicals and trace amounts of radionuclides required as an adjunct to microbiological studies.
• Type B2 cabinets exhaust the entire air handled in the cabinet. Type B2 cabinets may be used with biological agents treated with toxic chemicals and radionuclides required as an adjunct to microbiological studies
• Class III Cabinet is defined as a totally enclosed ventilated unit of gas tight construction with glove ports for access. The workspace is maintained at -ve pressure of >0.5" water gauge. Class III Cabinets are suitable for work with agents that require biosafety level 1, 2, 3 or 4 containment

Mark Air Class IIA/B3 Biohazard Safety Cabinets provide personnel, product, and environment protection. Class II Cabinets differ in the proportion as 70% air is re-circulated within the cabinet through high efficiency particulate air (HEPA) filtration. Velocity of airflow to the work zone creates an ultra-clean environment for product protection, where the remaining exhaust air is discharged out.

 

Features :

 

• The filter assembly is constructed in accordance with EN1822 requirements.
• All contaminated plenums are surrounded by negative pressure, virtually eliminating filter perimeter leaks. 
• The backward curved wheel with external rotor motor delivers classleading energy efficiency for lower operating costs. 
• Unique raised armrest design elevates the operator's arms to prevent inflow grille blockage which may compromise safety. 
• The cabinet work zone has no welded joints to collect contaminants or rust. 
• Glass sides eliminate the feeling of "working in a box", enhance cabinet lighting, and permit observation of procedures. 
• Actual sash opening is larger than tested opening, and improves reach into the work zone without compromising safety. 
• Programmable automatic UV light timer simplifies operation while extending UV lamp life and saving energy. 
• Built-in warm white, electronically ballasted, 5000k lighting provides excellent illumination of the work zone and reduces operator fatigue. The reliable lighting system is zero-flicker and instant start. 
• Powder coated work zone rear wall eliminates harsh reflections which may be associated with conventional stainless steel interiors. 
• Cabinets are KI-Discus tested on a sampling basis for performance integrity. 
• Bioclean cabinets are warranted for 3 years excluding consumable parts and accessories. 
• Additional IQ/OQ documentation is available upon request.

“Mark Air” Class II A/B3 Biohazard Safety Cabinets provide personnel, product, and environment protection. Class II Cabinets differ in the proportion  as 70% air is re-circulated within the cabinet through high efficiency particulate air (HEPA) filtration. Velocity of airflow to the work zone creates an ultra-clean environment for product protection, where the remaining exhaust air is discharged out.

An internal blower draws sufficient room air through the front grille to maintain a minimum calculated or measured average inflow velocity of at least 75 lfpm at the face opening of the cabinet. The supply air flows through a HEPA filter and provides particulate-free air to the work surface. Laminar airflow reduces turbulence in the work zone and minimizes the potential for cross contamination. An unducted Class II type A is not to be used for work involving volatile or toxic chemicals. The buildup chemical vapors in the cabinet (by re0circulated air) and in the laboratory (from exhaust air) could create health and safety hazards.  


Features :

• Unique Bio Clean Dynamic Chamber™ plenum.
• Negative pressure plenum surrounds contaminated positive pressure plenum; no fabric bags are used. 
• Dual, long-life ULPA filters for supply and exhaust (per IEST-RP-CC001.3) with 99.999% efficiency for particle size between 0.1 to 0.3 microns. 
• Angled supply filter matches cabinet profile to achieve best downflow uniformity. 
• Bioclean Sentinel™ microprocessor. 
• Frameless, shatterproof sash is easier to clean. 
• Ergonomically angled front improves reach and comfort. 
• Actual work access height is 45 mm (1.8") higher than tested sash opening. 
• Removable one-piece work surface simplifies cleaning. 
• Raised airflow grille maintains safety by preventing blockage. 
• Optional UV lamp is located behind control panel away from line of sight. (Does not apply to 1.8 m / 6' models.)
  
• Bioclean antimicrobial coating on all painted surfaces minimizes contamination. 
• Enhanced side-capture zones optimize containment. 
• Work area on Esco 0.9 meter (3') cabinet is equivalent to work area offered on larger 1.2 meter (4') conventional cabinet.

“Mark Air” The Class I biohazard safety cabinet is maintained under negative pressure, ventilated cabinet usually operated with an open front. All of the air from the cabinet is exhausted through a HEPA either into the laboratory or to the out side. The Class I BSC is designed for general microbiological research with low-and moderate-risk agents, and is useful for containment of mixers, blenders, and other equipment. These cabinets are not appropriate for handling research materials that are vulnerable to airborne contamination, since the inward flow of unfiltered air from the laboratory can carry microbial contaminants into the cabinet.   

Recommended for Product, Personnel & Environment protection only Air Balancing: 100% exhaust with incineration & working zone under negative

Mark Air Class III biological safety cabinet was designed for work with Microbiological agents assigned to biosafety level 4, and provides maximum protection To the environment and the worker. Access for passage of materials into the cabinet is through a double-door pass-through box that can be decontaminated between uses. Both supply and exhaust air are HEPA filtered. The exhaust air must pass through the Two HEPA Filters, or a HEPA filtered and an air incinerator, before discharge to the outdoors. Airflow is maintained by a dedicated independent exhaust exterior to the cabinet, which keeps the cabinet under negative pressure.
 Arm-length, heavy-duty rubber gloves are attached in a gas-tight manner to ports in the cabinet and allow for manipulation of the materials isolated inside. Although these gloves restrict movement, they prevent the users direct contact with the hazardous materials.

Features :

• Exhaust air is double-filtered through high-quality ULPA filters (per IEST-RP-CC-001.3) with typical efficiency of >99.999% for 0.1 to 0.3 micron particles, better than HEPA filters.
• Exclusive dual exhaust filters provide >100,000 times better protection than single-stage designs. 
• Microprocessor-based Esco Sentinel™ Silver control system provides visual / audible alarms for airflow. 
• Magnehelic pressure gauge* is mounted in the rear of the work zone for at-a-glance monitoring of work zone negative pressure. 
• Neoprene™ gauntlets are single piece leak-tested glove assemblies which guarantee maximum protection. 
• An integrated pass-through with interlocking doors, permits materials transfer without risk of environmental contamination. 
•  ISOCIDE antimicrobial surface on all painted surfaces minimizes contamination. 
• An angled cabinet front ensures an ergonomic working posture. 
• Cabinet operates at negative pressure relative to the laboratory in order to prevent migration of pathogenic materials out of the work area.
