Mix and divide a water sample into subsamples for testing.
The Churn Sample Splitter provides a convenient and
efficient method of preparing subsamples of collected
water-sediment mixtures from stream flows for water quality
analysis. Water sediment samples are customarily collected in
473 ml (1 pint) or 946 ml (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 subsamples using the Churn Sample Splitter.
USGS standard procedures allow use of the Churn Splitter for
suspended-sediment concentrations up to 1000 mg/l.
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 subsamples 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.
