Labculture® Class II, Type A2 Biological Safety Cabinets
Esco Labculture Class II Type A2 Biological Safety Cabinet combines Esco's experience of more than 20 years in biosafety cabinet technology. The Labculture combines a multitude of design, construction and proprietary technological considerations to bestow optimum operator, product and environmental protection. Utilizing 2 minipleat ULPA (Ultra Low Air Penetration) filters which operate at a typical efficiency of 99.999%, these surpass the conventional HEPA (High Efficiency Particulate Air) filters in contamination protection. Esco Labculture features a 10-degree sloped front for maximum operator comfort. A 1-piece stainless steel work zone and the absence of screws or connectors in the work zone facilitate ease of cleaning after experiments. The Isocide™ powder coating finish prevents microbial/bacterial growth on the exterior and delivers a sleek, elegant appearance fitting for the leader in biosafety cabinet technology.
- 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.
- Esco Sentinel™ Gold microprocessor.
- Quickstart mode, to turn the blower and lights on/off, by moving the sash window to correct position.
- RS 232 data output port enables remote monitoring of cabinet operating parameters.
- Frameless sash that 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.
- Esco ISOCIDE 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.

- Ambient air is pulled through the perforations located towards the work zone front to prevent contamination of the work surface and work product. The inflow does not mix with the clean air within the cabinet work zone. Inflow air travels through a return path toward the common air plenum (blower plenum) at the top of the cabinet.
- Approximately 35% of the air in the common plenum is exhausted through the ULPA filter to the room. The remaining 65% of the air is passed through the downflow ULPA filter and into the work area as a vertical laminar flow air stream bathing the work surface in clean air.
- The uniform, non-turbulent air stream protects against cross contamination within and throughout the work area.
- Near the work surface, the downflow air stream splits with a portion moving toward the front air grille, and the remainder moving to the rear air grille. A small portion of the ULPA filtered downflow enters the intake perforations at the side capture zones at a higher velocity (small blue arrows).
- A combination of inflow and downflow air streams forms an air barrier that prevents contaminated room air from entering the work zone, and prevents work surface emissions from escaping the work zone.
- Air returns to the common air plenum where the 35% exhaust and 65% recirculation process is continued.
