VIVA® Universal Animal Containment Workstations
Esco VIVA Universal Workstation draws on Esco's experience of over 25 years in laminar air flow technology. The enclosure employs two independently balanced ULPA filtration modules to protect animals inside the enclosure from exposure to airbone particulates/ambient contamination, as well as, the operator from exposure to allergens and other potentially hazardous materials. It employs an airflow recirculating design similar to a Class II Type A2 biosafety cabinet (operating principles described below).
Featuring an ergonomically sloped front design and integrated carbon filters to remove odors emitted, the VIVA Universal Workstation ensures the comfort of the operator during operations. Coupled with the standard protective features of precise airflow engineering, ULPA filtration techniques, Esco Sentinel™ Microprocessor control and Isocide™ antimicrobial powder coating , the VIVA Universal Workstation represents a complete solution to your need for ergonomics, reinforced safety and operations efficiency in animal handling operations.
Key Benefits:
- ELISA-verified allergen containment
- Biosafety cabinet class II containment
- ISO Class 3 workzone
- Motorized height stand (optional)
- Operator, Product and Environmental Protection via controlled inflow, downflow and exhaust similar to Class II Type A2 biosafety cabinet technology (described in detail below).
- ISO Class 3 air cleanliness within workzone as per ISO 14644.1 (equivalent to Class 1 as per the US Federal Standard 209E, 100 times cleaner than the usual Class 100 classification on cabinets offered by the competition).
- Disposable high-quality polyester pre-filter with 85% arrestance located under the work tray removes large contaminants and particles.
- Minipleat separatorless ULPA filter technology , operating at the typical efficiency of 99.999% at MPPS, 0.3 and 0.12 microns provides better operator, product and environmental protection than conventional HEPA filters. This cabinet employs 2 ULPA filters, 1 for downflow and 1 for exhaust airflow filtration.
- Esco Sentinel™ Microprocessor allows the operator to easily access and control all cabinet functions on the LCD screen. Audible and visual alarms alert the operator to unsafe sash position and low airflow (detected by our proprietary airflow sensing technology).
- Fail-safe system ensures that in case of airflow failure, the cabinet automatically shuts down to ensure safety to the operator and the environment.
- Esco Isocide™ antimicrobial powder coating prevents surface bacterial growth and enhances operator safety.

- Ambient air pulled through the perforations towards the work zone front prevents 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 40% of the air in the common plenum is exhausted through the ULPA filter to the room. The remaining 60% 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 ULPA-filtered 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 downflow enters the side capture zones at a higher velocity (small blue arrows).
- A combination of inflow and downflow air streams form an air barrier that prevents contaminated room air from entering the work zone, and prevents work surface emissions from escaping the work zone.
