All - Attached is a description of various types of biosafety cabinets and the BNC strategy for biosafety cabinet purchases. I pulled this together from various sources, relying mostly on the BMBL. Please feel free to distribute it as you feel it is appropriate. It goes into more detail than the existing Purdue Biosafety Manual, especially appropriate for those without a lot of experience in specifying biosafety cabinets. A special thanks goes to Guy Telesnicki, Lisa Reece, Bob Golden, and Jim Leary who provided additional technical information and reviewed the document. John John R.
