    Abstract: A cylinder-and-piston assembly for a bottle attachment apparatus for handling liquids in which the stroke length of the piston of the cylinder-and-piston assembly is delimited by a stroke length stop when suctioning from the cylinder and is delimited by a readjustment stop when exhausting into the cylinder. The readjustment stop is disposed on the piston or on the cylinder housing and interacts with a fixed stop. The readjustment stop is accessible and adjustable by way of a removable seal. The seal is connected by way of ribs to a piston bearing. The readjustment stop is disposed below this removable seal. The seal has a molding and the piston bearing has a counter molding. Displacement of the seal in relation to the piston bearing moves the seal in the longitudinal direction, and by this movement, the seal is removed in a manner that preferably is not capable of re-assembly.

    Abstract: A cylinder-and-piston assembly for a bottle attachment apparatus for handling liquids provides a cylinder attachable to a valve block assembly, a piston, displaceable in a sealed manner in the longitudinal direction within the cylinder, and a cylinder housing connected to the piston and externally encompassing the cylinder. The piston is displaceable in the cylinder and the stroke length of the piston in the cylinder is delimited by a fixed stop, which interacts with a stroke length stop on the cylinder housing. The cylinder housing has a longitudinal slot running in the longitudinal direction and on the external side thereof has a scale assigned to this longitudinal slot. The stroke length stop on the cylinder housing is adjustable in the longitudinal direction and is interlockable in the respective position.

    IPC: B01L3/02

    Abstract: A pipetting device for taking up and dispensing fluid volumes has a displacement device with a displacement mechanism and a displacement housing. The pipetting device has an adjusting device for changing the stroke of the displacement mechanism. The stroke of the displacement mechanism can be adjusted, and the corresponding adjustment value can be displayed by an adjustment indicator. A coupling device, in a use state, couples the adjusting device to a volume indicator and decoupled the adjustment device from the adjustment indicator. In an adjustment state, the adjusting device is coupled to the adjustment indicator and is decoupled from the volume indicator. The adjustment indicator displays an adjustment value for the stroke of the displacement means. The adjustment indicator can be adjusted in an adjustment state, whereas it is fixed in a use state.
