The scale has been magnified and high precision measurementsare possible. It is the best for measuring low concentrated These models are suitable for use with agents assigned to biosafety levels 1, 2 and 3 in particular 2 and 3 and provide unparalleled protection for the operator and the environment from biological hazards, in addition to an unequalled level of protection for the product from external airborne contamination and cross contamination.

Drawing from a dialogue of over 20 years with our users, Esco engineers have re-designed every component for better performance, longer durability and easier use.

Advanced airflow visualization has been employed during type-testing in our laboratories to ensure maximum containment for improved operator protection, and better airflow uniformity within the work zone for better product protection.

The industry-exclusive features designed into this cabinet include a world first patent pending backward curve motorized impeller replaces conventional blowers positive plenum design.

While the technology employed is state-of-the-art, the results obtained are simple to appreciate: better airflow uniformity for enhanced product protection, improved energy efficiency for lower operating costs, and a more comfortable working environment as a result of reduced noise and vibration levels.

Another key innovation for which Esco is now recognised for - our use of mini-pleat ULPA Ultra Low Penetration Air filter technology as opposed to conventional HEPA filters - is especially pertinent to the applications for which these cabinets have been designed for.

Operating at typical efficiencies of The type-testing performed included stringent evaluations of cabinet airflows, containment, and operator comfort factors. Class II cabinets provide product, operator and environment protection. They are suitable for general microbiological work with agents assigned to biosafety levels 1, 2, or 3. Class II cabinets are recommended for most applications and are the most common and cost-effective systems available on the market today.

The inflow moves from the room into perforations located towards the front of the work zone in order to prevent contamination of the product, the inflow does not mix with the clean air present in the actual work zone of the cabinet , and then travels through an air return path below the work surface. An ULPA-filtered vertical laminar flow air stream within the cabinet also referred to as the downflow - large light blue arrows on the airflow diagram moves downwards from the top of the work zone towards the work surface.

The uniform nature of the air stream ensures a high level of protection against cross-contamination between various samples placed at different locations within the cabinet work zone. Close to the work surface, the downflow air stream splits with a portion moving forward and entering the front air grille, and the remainder moving backward towards the back air grille. With the inflow, air is moved within the cabinet, through an air return path underneath the work surface, and behind the back wall to a plenum in which the blower system is mounted.

For the S-series: In addition, a small portion of the filtered downflow air enters the airflow intake perforations referred to as side capture zones at the front of the side walls at high velocities indicated on the diagram with small blue arrows. This forms an air barrier that ensures no contaminated air enters the actual work zone, and also prevents any contamination from escaping the cabinet.

Integral filter metal guard on ULPA filter prevents accidental damage to filter media; seamless filter gasket is permanently moulded on the filter frame and will not deteriorate over time. Removable perforated powder-coated downflow diffuser provides additional protection against filter damage; in addition to increasing downflow uniformity for better product and cross contamination protection.

Smooth, corrosion-resistant, attractive exterior is free of large protrusions and easy to clean. The large, generously sized interior with more usable working space for the operator. Interior surfaces are designed to eliminate protrusions, channels, and any other dif. Built-in white k fluorescent lighting offers excellent illumination throughout the work zone in order to reduce operator fatigue. Front sash sliding window is completely frameless for maximum visibility into the work zone.

An enclosure houses the sash as it is raised, thus preventing exposure to any biological hazards that may have adhered to the inside. Sash is counterbalanced to allow operation with minimal physical force and effort; a gas spring counter-balancing system is employed. Durable grade stainless steel work surface will never rust, chip, or generate particles.

Work tray s is are aesthetically designed with upward-curving back edge which makes cleaning the surface a breeze with no hard-to-clean joints. Side perforation holes along the side of the work tray s ensure fail-safe cross-contamination prevention by eliminating the possibility of any dead-air zones within the cabinet. The drain pan is generously sized to contain any liquid spills and can be easily cleaned.

No factory-fitting is necessary. E-series Features UV-absorbing tempered glass sides increase operator comfort and provide a high level of protection against harmful UV rays when a UV lamp is installed; glass is also stronger and more durable compared to plastic materials. Standard work surface is a multi-piece work tray. Each work surface tray is fabricated from a single piece of stainless steel without any fasteners, thus eliminating difficult-to-clean joints; each set of trays has lifting provisions to facilitate easy access to the lower drain spillage trough.

S-series Features Interior workzone is full stainless steel , which makes the workzone easy-to-clean. In addition, stainless steel is aesthetically pleasing to the eyes. Standard work surface is a single-piece work tray.

Micro-holes near the front edge of the sidewalls behind the sliding sash eliminate the possibility of dead-air pockets.
