A machine for washing Wassermann tubes.

One of the most irksome tasks in a pathological department is the washing of test-tubes. Particularly is this so when a thousand or more tubes have to be washed at the end of a long day doing Wassermann and Kahn tests. If the task is postponed to the next day the cleaning process becomes more difficult. It seemed that a machine was needed for the mechanical rinsing of tubes immediately after the conclusion of the tests. The apparatus to be described has been in use in this laboratory for several months and serves as an efficient rinsing machine.
