There is disclosed a waste prevention system which avoids the discharge, inadvertent or otherwise, of laboratory waste, into a public sewage system and subsequently into the natural environment. The system employs, in combination, a laboratory sink having cooperatively connect thereto a carboy for collecting pollutants. The carboy is provided with elements to permit removal of samples of materials delivered thereto from the sink for testing of the same to determine the presence of pollutants. In the event no pollutants are present, the carboy may simply be opened and any wash or rinse water from the sink can be delivered into a public sewage system and then to the environment. In the event testing indicates the presence of pollutants, the carboy then can be filled to the required level, which is indicated by a sensing device connected electrically to signaling devices, such as a horn and/or light and which is also connected to the source of washing water and automatically will stop the flow of such washing water into the sink. The carboy can then be removed from the system and stored and/or disposed of, as desired.

Pollution prevention system

An exhaust system has an air exhaust duct having a charge opening and a discharge opening and defining an air flow path. A damper is mounted in the duct for maintaining a constant air velocity for air exiting the discharge opening. The damper has opposing damper blades pivotally mounted within the duct. Each damper blade has an end that is pivotally mounted in cantilevered fashion within the duct so that an opposing end is free to move within the duct. Each damper blade is parabolic in shape and minimizes the air turbulence over the damper blade and reduces vibration. Each damper blade can be pivoted in response to a change in air volume discharged through the discharge opening to maintain a desired velocity of air through the discharge opening.

There is disclosed a high containment device, apparatus or system for withdrawing sample material from process or manufacturing equipment with substantially no leakage of the sample material to the external environment and which is of syringe-type construction, thus preventing possible contamination of such environment or workers operating processing and/or production equipment in such a situation, especially where hazardous materials are involved. The high containment device, apparatus or system disclosed is used in combination with process or manufacturing equipment thus providing a system which results in the prevention of leakage of possible hazardous material to the environment and possible contamination of equipment operators thereby.

High containment sampler

Apparatus is provided for charging a bioreactor with feed material through a sight port in the bioreactor vessel wall without compromising sterility of the material or the vessel or releasing organisms from the vessel to the surrounding atmosphere.
