Abstract
The containment of biohazardous substances, which may exist in the streams of sample material that are being separated in air into droplets in a testing chamber of equipment, such as cell sorters and cytofluorometers, is attained by subjecting the testing chamber to negative air pressure, so that inward air flow at the open face of the chamber is sufficient to inhibit biohazardous substances from exiting out from the face of the chamber. A region of air stagnation is created around the sample streams so that the streams are not deflected from their paths, such paths being pertinent to their testing of the biological sample material. The air stagnation region is formed by interposing an air diverter between the sample streams and the air flow exhaust port at the rear of the testing chamber.
