Abstract
An uncapping apparatus for a test tube cap includes a drive head having at least two drive head elements. The drive head elements have a first section and a second section located on two opposite sides of a rotary shaft. An elastic element provides a tensioning force to the drive head elements. A switching element is movable between a first position and a second position. In the first position, the second sections are under the tensioning force of the elastic element to cause the first sections to form a first drive head size. In the second position, the switching element acts on the elastic element to change the tensioning force acting on the second sections, so that by rotation of the drive head element, the first sections form a second drive head size. A method for using an uncapping apparatus to open a test tube cap is also described.
