Abstract: A balance includes a weighing cell with a vertically movable load receiver, a weighing pan to receive a weighing load, and a support element to couple the weighing pan to the vertically movable load receiver of the weighing cell. A cantilever arm with a seat for at least one calibration weight is solidly connected to the support element. The balance has a coupling arrangement that constrains the support element with low-friction mobility to the load receiver at three points forming a triangle in a plane that extends orthogonal to the symmetry plane of the weighing cell, wherein the triangle is symmetric to the symmetry plane of the weighing cell. Under the coupling arrangement, the support element is solidly supported on the load receiver in the direction in which the weighing load is acting.

Abstract: A draft protection device for a balance, which encloses a weighing compartment surrounding a weighing pan, has at least one opening that can be closed by a window. The at least one window has at least two slidable window sections which partially overlap each other in any of their positions. According to the invention, a drive mechanism is provided for the opening and closing of the window, which drive mechanism couples the window sections to each other in such a way that all of the window sections move simultaneously and at different speeds during the opening and closing, wherein a fixed ratio between the respective speeds of the window sections can be predetermined by design.

Abstract: A balance (1) with a weighing pan (3) inside a weighing compartment (2) enclosed by a draft shield (4) has at least one thermoelectric module (16) that is arranged outside of the weighing compartment (2) and thermally connected to a stationary part of the balance (1). At least one vertical wall (8) of the draft shield (4) has a lower end portion in thermal connection with the thermoelectric module (16). The vertical wall (8) is configured in such a way that a temperature gradient develops in the vertical wall (8), wherein the temperature increases from the bottom to the top of the wall (8).

Abstract: A balance (1) has a weighing compartment (4) that borders on a stationary part (8, 9) of the balance and is otherwise enclosed by at least one side wall panel (5, 6), a front wall panel (7), and a top cover panel (12). At least one of the panels is slidable by means of a guiding device (17, 20) to open and close the weighing compartment (4). The balance (1) further has cutout passages (20) in the side wall panels (5, 6), the front wall panel (7), the top cover panel (12), and/or the rear wall of the weighing compartment, so that cables and/or conduits can be introduced from the outside into the weighing compartment.

Abstract: A balance with a draft shield enclosing a weighing pan (33) has slidable walls (6, 7, 8) with slide handles (10, 110, 210) to open and close the weighing compartment (2). A connector body (22) serves to couple non-adjoining slidable walls (6, 7, 8) to each other. Besides for pushing the slidable walls open and closed, the slide handles (10, 110, 210) also serve to couple and uncouple the slidable walls, so that more than one wall can be moved simultaneously using only one hand, or a wall can be moved by pushing a handle on the opposite side. The slide handles are configured as pairs of handle elements that are attached either to adjoining walls or to a wall and an adjoining place on the connector body. In the coupled state, the pairs of handle elements are folded or swiveled into each other, working as a single handle, e.g., for two adjoining walls. In the uncoupled state, they move the walls individually.

Abstract: A balance is connectable to a display/operating unit (13) through a cable (14). The display/operating unit (13) can be placed either adjacent to the housing (1) or at a distance from the housing (1). For storing the unused length of cable (14), a corridor compartment (24) with at least one exit opening (22, 29, 30) for the cable (14) is arranged at the bottom (6) of the balance housing (1). When the cable (14) is pulled out or pushed in, it can move freely inside the corridor compartment (24). The display/operating unit (13) is held in place at the balance housing (1) by means of an intermediate member (10) in an arrangement where the balance and the display/operating unit are resting independently of each other on a supporting surface.

Abstract: A balance includes a weighing compartment and a balance housing containing a weighing cell, wherein the balance housing forms a rear wall and a floor of the weighing compartment. A weighing-load carrier is coupled to a coupling arrangement extending through passage openings formed at the rear wall. The weighing-load carrier that is configured as a level grate. The floor extends without openings below the weighing-load carrier.

Abstract: An apparatus for the gravimetric calibration of multi-channel pipettes contains a balance that has a load receiver configured to support receptacles containing a substance to be weighed. The apparatus has a holder device to support a certain number of the receptacles into which a test liquid is dispensed from the multi-channel pipette. The apparatus further has a transport device for advancing the holder device towards the load receiver. The receptacles are seated in the holder device at equally spaced positions and are one by one delivered to and subsequently removed from the measuring device.

Abstract: A balance (1) has a weighing compartment (4) that borders on a stationary part (8, 9) of the balance and is otherwise enclosed by at least one side wall panel (5, 6), a front wall panel (7), and a top cover panel (12). At least one of the side wall and top cover panels is slidable by means of a guiding device (17, 120) to open and close the weighing compartment (4). A holder arrangement (15, 17c, 58, 125) for the at least one slidable panel (5, 6, 12) is integrated in the guiding device (17, 120), and a holder arrangement for a non-slidable panel is integrated in the stationary part (8). The holder arrangements (15, 19, 17c, 58, 125) releasably connect the panels (5, 6, 7, 12) to the balance by means of form-locking closure devices, so that each panel (5, 6, 7, 12) can be attached to the balance as well as released for removal from the balance by applying a force to the panel (5, 6, 7, 12) and/or the holder arrangement (15, 19, 17c, 58, 125).

Abstract: A balance (1) has a balance housing (21) and an operator panel (4). The operator panel (4) cooperates with the balance housing (21) and is connected, or connectable, to the latter in such a manner that the operator panel (4) can be folded up from a working position into a rest position (4′) by rotation about a pivot axis (A) that runs essentially parallel to the balance housing (21). The mechanical connection is made through a pivoting arrangement which allows the operator panel (4) to rest firmly on a supporting surface, independent of the level adjustment of the balance housing (21). Furthermore, the operator panel (4) is configured to be completely detachable from the balance housing (21). Electrical signals are transmitted either through a cable or by a wireless mode of communication.
