An instrument () for powderous or pasteous substances has a control unit () and a dispensing unit (). The control unit is configured as a grip handle to be handheld. The dispensing unit is designed for removable seating in the holder device. A vertically movable shutter bolt () can open a discharge orifice (). The control unit () has an actuator () directed at the shutter bolt, with a motor (), a transmission (), an actuator element () and a drive shaft (), oriented vertically when operated. The drive shaft () can be engaged with the shutter bolt. Continuing and increased actuation of the actuator element moves the shutter bolt into an opening range where the shutter bolt opens up the discharge orifice to a variable, position-dependent extent, allowing the material to flow into a target vessel.

Handheld dosage-dispensing instrument for powderous or pasteous dosage material

A dosage-dispensing device, for substances in powder- or paste form, includes a supply container and a dosage-dispensing head that is connected or connectable to the supply container. A housing has an outlet orifice of circular cross-section and a delivery- and closure element with a closure portion serving to close off the outlet orifice. The device further has a conveying tool with at least one conveying element that serves to direct the substance to the outlet orifice, wherein the outlet orifice and the delivery- and closure element are arranged on the central lengthwise axis of the dosage-dispensing head. The conveying tool is rotatable about the central lengthwise axis in relation to the housing and the at least one conveying element is designed to move on a circular path about the central lengthwise axis. The delivery- and closure element includes a delivery portion which serves to deliver a substance that is to be dispensed, and the delivery- and closure element is configured to be rotatable about the central lengthwise axis in relation to the housing and to be capable of translatory displacement along the central lengthwise axis relative to the outlet orifice. The at least one conveying element of the conveying tool which serves for the delivery of substance is slanted in the direction of its rotation at an acute angle to the plane of its circular path.

Dosage-dispensing device for substances in powder-or paste form

A laboratory instrument with a housing containing a weighing cell has a working compartment that is connected to the housing. The working compartment has a floor, a top cover, a rear wall, a front wall and two sidewalls. Arranged in the working compartment is a load receiver which is connected to the weighing cell. Also connected to the housing is at least one guiding device which serves to guide a linear movement and simultaneous swivel movement of individual portions of the front wall or the entire front wall.

Laboratory instrument with a protected working compartment

A dosage-dispensing device for substances in powder- or paste form is equipped with a supply container and with a dosage-dispensing head that is connected or connectable to the supply container and has a housing with an outlet orifice of circular cross-section. The dosage-dispensing head further has a delivery- and closure element, wherein the outlet orifice and the delivery- and closure element are arranged on the central lengthwise axis of the dosage-dispensing head, and the delivery- and closure element is designed to be rotatable about the central lengthwise axis in relation to the housing and to be capable of translatory displacement along the central lengthwise axis, so that the delivery- and closure element can be moved out of, as well as into, the outlet orifice. The delivery- and closure element, in its basic configuration is of a cylindrical shape and has a cylindrical closure portion that serves to close off the outlet orifice and, adjacent to the closure portion, a delivery portion that serves to deliver the substance to be dispensed. When the dosage-dispensing device is in its operating state, the delivery portion is located in the lower part of the delivery- and closure element. Said lower part has an end surface that is inclined at an oblique angle relative to a plane that extends orthogonal to the central lengthwise axis, wherein the end surface at its lowest point forms a tip that coincides with a point on the cylindrical surface, and the topmost point likewise coincides with a point on the cylindrical surface.

Dosage-dispensing device for substances in powder or paste form

A weighing lift has a single-piece platform for an electronic balance and a holder into which the platform can be plugged. The platform has a load-receiving area for an object to be weighed, a centering pin and a rotation-blocking element. The rotation-blocking element is arranged between the load-receiving area and the centering pin. The single-piece platform is preferably made from a sheet metal material. The platform can be plugged substantially without loose play into the holder. The holder has at its end a first coupling portion with a wedge-shaped groove serving to receive the rotation-blocking element. It also has a body in which a receiving seat is formed for the centering pin, which serves to position the platform parallel to the load direction of the object.

Weight-receiving platform for a balance and a holder therefor

Electronic balance with a load carrier, further with a transfer device cooperating with the load carrier, with a draft shield enclosing a weighing compartment that is adapted to the dimension of an object to be weighed and comprises at least one closure element serving to open and close at least one loading access opening, and also with a drive mechanism serving to actuate the closure element, characterized in that the drive mechanism further comprises a position-setting member, wherein the drive mechanism together with the position-setting member and a displacement-transmitting element causes a lifting- and lowering movement of the transfer device relative to the load carrier, and wherein the position-setting member is configured for setting the transfer device and/or the load carrier into several defined positions.

Electronic balance

A support device for a weighing cell is mounted on one or more support posts resting on support springs that are connected to a stationary chassis and are pre-tensioned with an upward force. In case of a downward-directed shock, the support springs will yield to the inertial shock force and allow the weighing cell to move downward. The support posts can lift off from their resting places on the support springs, but are constrained by guide members to a limited range of upward vertical movement. A balance equipped with the support device has a low profile height and protects the weighing cell from downward- as well as upward-directed shocks.
