A system and method for dispensing a powdered pharmaceutical into a bottle is disclosed. The system includes a filler having a powder filler head and respective weight sensor, two or more draft shields, and one or more static reduction devices. In some embodiments, the system also includes one or more dust extractors. In some embodiments, the static reduction device is an active static reduction device, such as one or more static bars. The two or more draft shields may include an inner draft shield to reduce small pressure and/or airflow changes and an outer draft to reduce large pressure and/or airflow changes.

A gravimetric measuring system (10), includes a balance (12) with a weighing chamber (22), surrounded by a weighing chamber wall (23, 24, 26, 28); an electromechanical weighing system (181); and an electronic control apparatus (36) for controlling the system operation according to algorithms stored in a memory (363) thereof; and a plurality of functional modules (14, 16), configured to be inserted, into module receptacles (283), arranged on the weighing chamber wall (28). Each module receptacle (283) has a device-side identification interface component (30a); and each functional module has a corresponding module-side identification interface component (306). The control apparatus (36) identifies each functional module (14, 16) inserted into a module receptacle (283), through interaction between the respective device-side and module-side identification interface components (30a, b) and selects one of a plurality of operating routines according to algorithms stored in the memory.

A windshield structure (30) is provided for a weighing balance (100) having a base body (48), a floor (46), and a load receiving arrangement (11). The base body and the floor, which is attached to the base body, are positioned horizontal to the ground surface. The load receiving arrangement has a load receiver, with the windshield structure arranged below the load receiver. The windshield structure has a central portion and a circumferential portion that surrounds the central portion. The central portion also has a topological surface with a plurality of alternating hills (32) and valleys (31) which aid in regulating airflow below the load receiver.

Provided is an electronic balance that includes a windshield having a door to be automatically opened and closed, and has a high degree of freedom of design. An electronic balance including a balance main body that holds a weighing mechanism connected to a weighing pan, and a windshield including a frame and doors disposed slidably on the frame, and configured to form a weighing chamber by covering the weighing pan, and configured so that the windshield includes inside air cylinders connected to the doors to open and close the doors, and air pumps to drive the air cylinders, and is configured to be detachable from the balance main body. The windshield that has doors to be automatically opened and closed is detachable from the balance main body, so that the windshield and the balance main body can be designed separately, and therefore, the degree of freedom of design of the electronic balance is high.

Provided is a balance with a windshield having a door to be smoothly opened and closed either manually or automatically. Provided is an electronic balance with a windshield including a balance main body including a weighing mechanism connected to a weighing pan, a windshield having doors capable of opening and closing by sliding, and configured to form a weighing chamber by covering the weighing pan, and actuators configured to open and close the doors, wherein the actuator includes a double-acting type air cylinder having two ports serving as air intake ports, an air pump-to be connected to the two ports, two valves respectively interposed between the air pump and the two ports and configured to make the ports communicate with and shut off from the atmosphere, and a control device configured to control the two valves-to make the two ports communicate with the atmosphere when the air pump is stopped. Without a special mechanism, switching between automatic opening and closing and manual opening and closing can be made, and in either automatic or manual opening and closing, the doors of the windshield are smoothly opened and closed.

The present invention relates to an electronic balance with a windshield having a door to be automatically smoothly opened and closed. Provided is an electronic balance including a balance main body including a weighing mechanism connected to a weighing pan, a windshield configured to form a weighing chamber by covering the weighing pan, slidable doors provided in the windshield and constituting portions of the weighing chamber, holders configured to support the doors from upper portions in a hanging manner, guide members configured to engage with the holders and slidably support the holders, and air cylinders connected to the holders and configured to slide the door through the holders. The holders supporting the doors in a hanging manner are directly moved by the air cylinders, so that the doors can be smoothly opened and closed.

A laboratory balance (1) has a base body (2), a weighing chamber (10) with a weighing chamber floor (3), a weighing chamber rear wall (4), and a draft shield (5,5′,5″). The draft shield has a top wall (6), a first side wall (7), a second side wall (8) arranged parallel to the first side wall, and a front wall (9). The weighing chamber floor, the draft shield and the weighing chamber rear wall act together to enclose the weighing chamber. The weighing chamber rear wall has a modular construction, with at least a base module (15) and a top module (16,16′,16″). The base module is connected to the base body, and the top module is connected to the top wall of the draft shield.

A laboratory balance (1) has a housing, a base body (2) with an upper side (20) facing a weighing pan (14) and an underside (21) facing in the opposite direction of the upper side (20). A draft shield (5) is mounted on the upper side of the base body. The draft shield has a top wall (6), a first sidewall (7), a second sidewall (8) that is to the first sidewall, and a front wall (9). The first sidewall is operated by a first motor unit (25) which is located in the base body. The underside has a first opening (37) that provides access to the first motor unit.

A draft shield (5) is provided for a laboratory balance (1) with a base body (2), a weighing chamber (10) with a weighing chamber floor (3) and a weighing chamber rear wall (4). The draft shield has a top wall (6), first and second side walls (7, 8) and a front wall (9). The draft shield, the weighing chamber floor and the weighing chamber rear wall enclose the weighing chamber. A drive unit (19) connected to the top wall serves to open and close the top wall (6). The weighing chamber rear wall has a base module (15) and a top module (16), at least a portion of which is configured as a compartment. The drive unit is arranged in the compartment-shaped portion.
