Abstract: A door leaf (14) for a door system (10) has a main component (24), a carrier profile (26) and a strap (28). The main component (24) has an upper end face, a front end face, a lower end face and a rear end face, wherein the carrier profile (26) is attached to the upper end face. The strap (28) has a first end (38) and a second end (40), wherein the strap (28) is attached to the carrier profile (26) with the first end (38), subsequently extends along the front end face, the lower end face and the rear end face of the main component (24) and is subsequently attached to the carrier profile (26) with the second end (40). Further, a door system (10) is shown.

Abstract: A manipulation system for microscope applications comprises a micromanipulation tool and a protective device protecting the tool, wherein the tool and the protective device are movable relative to one another between a position protecting the tool in a contactless manner and a position releasing the tool for the manipulation.

Abstract: The invention relates to an automatic door system including a first door leaf of a first door leaf arrangement that can be displaced in the longitudinal direction. A floor-side guide rail arrangement extends in the longitudinal direction and includes a first floor rail arrangement. The at least one first door leaf includes an engagement element which is arranged on an underside of the at least one first door leaf. The at least one first floor rail arrangement includes at least one first floor rail and at least one connection and/or functional element, wherein the at least one connection and/or functional element is arranged on an end side of the at least one first floor rail. The at least one first floor rail includes at least one first guide groove extending in the longitudinal direction.

Abstract: An automated high-precision plunger pump for volumes of less than 1 microliter, which is used in the microscope-assisted micromanipulation of biological material, comprises a housing (1) and a pump head (8) that defines a working chamber (9) with a common or separate inlet and outlet opening (10), wherein the volume of the working chamber (9) can be altered by an axially movable plunger (7) that can be introduced into it. The plunger (7) is axially movable via a threaded spindle (5) or a spindle nut (6) arranged in threaded engagement on the threaded spindle (5), and the threaded spindle (5) and/or the spindle nut (6) can be rotationally driven and the respective other component is designed to be rotationally lockable.

Abstract: The invention relates to a prestressing element for prestressing a measuring sensor arranged between structures or in a recess of a structure. The application and release of the prestress can only be carried out at one point by means of a key. The invention also relates to an arrangement of a plurality of prestressing elements which can be individually prestressed and released with the same tool.
