The Scienceware® Churn Sample Splitter provides a convenient and efficient method of preparing sub-samples of collected water-sediment mixtures from stream flows for water quality analysis. Water sediment samples are customarily collected in 473mL (1 pint) or 946mL (1 quart) bottles using suspended sediment samplers. The contents of the bottles are poured into the sample splitter where the samples 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 sub-samples using the Churn Sample Splitter. The polyethylene sample splitter consists of a thick walled cylindrical vessel with a disc churn. The disc has holes in a specific pattern, a center handle that extends through the cover and a locating notch to keep it oriented in one direction. A small polypropylene spring loaded spigot drains the sub-samples into bottles for delivery to the water quality laboratory. A swing type handle makes carrying the full or empty vessel easy. Lid and spigot are replaceable.
