Provides an efficient method of preparing subsamples of collected water-sediment mixtures from stream flows for water quality analysis. Water sediment samples are poured into the sample splitter where they are composited into one representative cross section sample of the stream flow. This composite can now be split into the required four to sixteen representative subsamples.
Polyethylene sample splitter consists of a thick walled cylindrical vessel with a disc churn
Center handle extends through the cover and a locating notch keeps it oriented in one direction
Small polypropylene spring-loaded spigot drains the subsamples into bottles for delivery to the water quality laboratory
Carrying handle makes carrying the full or empty vessel easy
Intended to meet USGS water sampling protocol
Lid and spigot are replaceable
