ESCO Labculture® Class II Type B2 B-Series Biosafety Cabinets

Incorporating all the latest design features available on Esco’s Labculture®Class II Type A2 biohazard safety cabinet, Esco Labculture®Class II Type B2 biohazard safety cabinets are designed to provide product, operator and environment protection and are suitable for general microbiological work with agents assigned to biological safety levels 1, 2, or 3.

In a Class II Type B2 cabinet, all inflow and downflow air is exhausted via ductworks after HEPA/ULPA filtration to the external environment without recirculation within the cabinet.

These cabinets are supplied with an integral exhaust collar that allows the cabinet exhaust to be ducted to the external environment via dedicated ductwork. Because they incorporate a non-recirculating total exhaust design, Class II Type B2 cabinets are suitable for work with toxic chemicals when these may be used as adjunct to microbiological processes. Total exhaust also serves as an additional fail-safe in case exhaust ULPA-filtration fails to ensure containment. The Labculture® Class II Type B2 cabinet is now available with Esco’s latest Sentinel™ Microprocessor Cabinet Control system which further enhances the cabinet function, usage and security features.

High-quality ULPA downflow filter with a typical efficiency of 99.9999% at MPPS, 0.3 and 0.12 microns provide the best product and operator protection in the world, while HEPA exhaust filter with a typical efficiency of 99.99% at 0.3 microns provides environmental protection. Typical filter lifespan is more than 3 years.

The exhaust sensor monitors the exhaust airflow and if exhaust airflow is lower than the minimum safe airflow, the sensor automatically shuts down the cabinet fan. This interlocking system prevents the reduction of inflow which can compromise operator protection.

ISO Class 3 air cleanliness within work zone as per ISO 14644.1 (equivalent to Class 1 as per US Federal Standard 209E, 100 times "cleaner" than the usual Class 100 classification on cabinets offered by other manufacturers).

The sleek, ergonomically styled 10-degree sloped front eliminates glare and increases operator-reach into work zone with less physical strain. The 5000k colour temp fluorescent lighting system is used for less glare and greater operator comfort. A large 203 mm / 8 inch (258 mm / 9.8 inch, measured from work surface) work access opening allows easier access into the work zone.

Front armrest is raised above the air grille perforations to prevent the operator’s arms from blocking air inflow during usage. In addition, front perforations are curved to prevent users from placing any objects on the grille itself.

The sidewall is closed which enhances cleanability - there are no perforations, air return slots, or hard to reach hidden areas where contaminants can accumulate. Especially unique is the single joint between the side wall liners and the lower drain pan which is sealed rather than left open as is usually the case with other designs.

The cabinet sidewall is under negative pressure. This means, as a system, the cabinet is inherently safe. Even in the event both internal and external walls are punctured, there will still be no leakage of contamination from the cabinet. Single wall designs employed by many other brands can result in safety hazards if seals fail.

Inherently safe design maintains containment for protection even with some or all work trays removed, thus preventing hazardous exposure during cleaning and maintenance.

Aerodynamically designed front airflow intake zone eliminates turbulence and the possibility of loss of containment. In addition, potential air leakages are prevented by the enhanced side capture zones between the work surface and the cabinet sidewalls.

For maximum safety, in case the sash is raised above the correct operating height, thus compromising containment, built-in Esco Sentinel™ Microprocessor control system will alert the operator with audible and visual alarms. A unique standby mode is activated automatically when sash is lowered below correct operating height.

All electrical penetrations into and out of contaminated areas are meticulously sealed and pressure-tested at the factory.

The electrical system of the cabinet has been designed in accordance with the requirements of the following standards: IEC 61010-1, EN 61010-1, UL 3101-1 and CSA C22.2 No. 1010.1-92. All components are UL-listed or recognised.
