Abstract
The invention relates to a method for applying objects such as antibiotic disc to a surface (2), e.g. the surface of a culture medium, by impaling them on an axially movable needle (3), which applies the object to the surface, after which a member (4) presses the object against the surface. The needle and the member are thereafter returned to the relative starting position. Moreover, the invention concerns a device for applying objects (1), such as an antibiotic disc to a surface (2), such as the surface of a culture medium, which device comprises at least one axially movable needle (3), a feeding surface (5), at least one hole (6) located in the feeding direction and at least one member (4) arranged so that it can press the object against the surface (2).
Claims7
A method for applying an object, such as an antibiotic disc, to a receiving surface, such as the surface of a culture medium, characterized by the steps of supporting the object on an intermediate surface with at least one hole located therein, moving a needle axially from a starting position, piercing the object by the needle, positioning the intermediate surface such that a hole is aligned with the needle, passing the object through the hole in the intermediate surface, applying the object to the receiving surface by means of the needle, pressing the object against the receiving surface by a member separate from the needle, and returning the needle and said member to their respective starting positions in that order.
An apparatus for applying objects, such as an antibiotic disc, to a receiving surface, such as the surface of a culture medium, said apparatus comprising supply means holding the objects and means for feeding out the objects from said supply means, characterized by the provision of at least one intermediate surface formed with holes therein, by the provision of at least one pointed needle capable of axial travel from a starting position into a position wherein it will pierce by its point an object lying on said intermediate surface, said intermediate surface being operable to bring one of said holes in alignment with said needle, said needle being further operable to convey said object through said hole down onto the receiving surface, and further by the provision of object retaining means operable to perform a motion cycle independent of that of the needle whereby to keep the object affixed to the receiving surface temporarily during withdrawal of the needle.
