Abstract
A liquid recovery device includes a receptacle, a swab for transferring a sample to a liquid in the receptacle, and a wringing unit to remove the liquid from the swab after the sample is transferred. The wringing unit has a sleeve with a closure in one end. A shaft of the swab extends through a passageway in the closure. When the swab in the receptacle is raised by upward movement of the shaft, an absorbent pad on the lower end of the shaft enters the passageway and is compressed. The compression of the pad wrings liquid therefrom which drips back into the receptacle. The device may be used in a method to prepare solutions of the sample in a minimum amount of liquid.
