Cabinet provides airflows & biological safety performance as specified. Cabinet is constructed from 16 GA, Type 304 stainless steel forming an all welded, monolithic, sealed structure.HEPA filter is of full cabinet work zone width and depth; work zone below supply HEPA is of fixed cross-sectional area (sloping back wall or viewing window is unacceptable). Supply HEPA filter is protected by a perforated metal diffuser covering the entire top of the work zone. Air Velocity from the supply filter averages 65 to 75 FPM (.32 to .38 m/s) with no single point outside the 20% of average range measured in a horizontal plane defined by bottom edge of window.The cabinet is ergonomically designed for maximum user comfort and adjustability to meet the requirements of the Americans with Disabilities Act (ADA.)

  • Standard non-metallic armrest/airfoil incorporating large 1 1⁄2 inch (38mm) forearm support area with 1⁄2 inch (12mm) recessed front grill designed for armrest comfort while maintaining containment performance.
  • Maximum visibility into cabinet workzone is at least 221⁄4 inches (565mm) from front access airfoil to exterior light housing.
  • Cabinet has a centrally located instrument panel within the control center that is easily serviced with quick disconnects.
  • Cabinet has the capability of incorporating a user adjustable base stand or base storage cabinet as an option.
  • The cabinet has a smooth operating sliding window from full closure to full opening at 19 1⁄2 inches (495mm).
  • Cabinet has a large work tray (17 7⁄8 inch (454mm) depth) removable with coved corners for easy cleaning.

The cabinet has all positive pressure plenums surrounded by a vacuum relative to the room (the LABGARD™ employs the HEPEX™ Zero Leak Airflow System). Electrical power is supplied with a 12 foot (3.6m), 3-wire cord with molded plug. Electrical supply should be 115 VAC, 60 Hz (current rating varies per cabinet size, reference Electrical Requirements) protected with thermal circuit breaker from distribution panel.

  • The cabinet has two internal electrical circuits; one for blower/lights and one for the duplex outlets. Each circuit is protected with a circuit breaker located in the Control Center.
  • The cabinet is listed by Underwriters Laboratories to meet the requirements of both the U.S. and Canada for electrical/mechanical integrity.
  • Total cabinet airflow is controlled via a solid-state motor voltage regulator with adjustment available on the Control Center.
  • Balancing of cabinet work zone down flow (recycling flow) to exhaust flow is accomplished with an internal exhaust flow damper, externally adjustable with screwdriver and sealed with liquid tight fastener.
  • The cabinet is easily transportable through a standard 36-inch (914mm) wide door without disassembly.
  • Sound level is no more than 67 dbA measured 15 inches (381mm) above the work tray and 12 inches (305mm) in front of viewing window.
  • Fluorescent lighting is externally mounted and provide 90 (968) to 120 (1291) foot-candles (LUX) on work surface. The ballast to be electronic containing thermal protection with automatic reset.

Hood, Bio, Forma Scientific model 1168, 6 foot, with 2-foot high metal stand. Class II, Type B2, Biological Safety Cabinet provides maximum personnel, product and environment protection by maintaining ultra-clean laminar airflow and total exhaust of the entire work zone. Total exhaust makes these units ideal for work that generates non-explosive chemical vapors and gases. Type B2 units may be used for work with agents assigned to biosafety levels 1, 2, or 3 treated with volatile toxic chemicals and radionuclides are required as an adjunct to microbiological studies.

  • Cabinet Style Benchtop
  • Window Style Sliding
  • Sash Opening 8.0" (20.3cm)
  • Electrical Outlets 2 (One on each side)
  • Service Valves 2 (One on each side)
  • Additional Service Valve Penetrations 2 (One on each side)
  • Dimensions: Length 74˝ x Height 64˝ plus stand x Dept 36˝ with light fixture (33˝ without light fixture)
  • Working Area: 71˝ x 25˝

This hood should be vented out of the building using an external blower. Unit comes fully refurbished with a 90-day warranty.
