Babcock bottle (original) (raw)

A Babcock bottle is a clear glass flask with a long graduated neck, used in the Babcock test to evaluate the cream contents of milk. It is also called a Babcock milk test bottle, milk test bottle, cream test bottle, and other similar names. This bottle (or variations thereof) may also be used to estimate the amount of a lighter phase in other two-phase mixtures, such as are obtained in standard tests for gasoline and other petroleum products.
