Liquid secretions are rapidly absorbed between the perpendicular fibers by capillary action.
Rotate the swab two to three times and hold the swab in place for 5 seconds to ensure maximum absorbency.
Strong capillary hydraulics between the strands of Nylon maximizes liquid sample collection.
Put the swab in the transport medium and break the shaft at the painted breakpoint.
Sample elutes automatically and rapidly because it is held very close to the surface in a totally open structure.
This does not hinder the flow dynamics, so the entire sample is released.
