  • Sample collection system
    Patent number: 6925895
    Abstract: A system for collecting a representative, non-contaminated sample includes a sample intake positioned in a chosen location within a body of liquid. A first conduit section transfers a sample, which has been withdrawn from the body of liquid, from the sample intake to the pump. A second conduit section transfers the sample from the pump to a receptacle for collecting the sample. The second conduit section is connected to the receptacle by means providing for an air and watertight seal for the receptacle, which is coupled with means providing for the escape of air from the receptacle during collection of the sample therein. The means providing for an air and watertight seal for the receptacle is a specially designed transfer cap.
