ABSTRACT:
A liquid sampling device is disclosed which is particularly suitable for sampling chemical wastes or hazardous chemicals. The device has a low resistance to flow so that composite samples can be obtained from a singal draw. A representative sample can be obtained of a liquid in a container throughout its depth, as opposed to taking several samples at various depths. The possibility of cross-contamination, when taking samples from several containers, is reduced as a result of fewer internal components and simplified replacement of contaminated parts. The overall structure, particularly that of the container for receiving and holding the sample, is simplified to make its production cost low enough for a disposable arrangement.
