The magnetic bar goes into the test vial, the vial sits on the base, and the unit agitates the sample consistently while you count drops or wait out a development time.

It is designed for the few minutes a water test takes.\u003c\/p\u003e\n\u003ch4\u003eWhat size test vials does it take?\u003c\/h4\u003e\n\u003cp\u003eVials up to 27 mm in diameter, which is the size of the holder.
