The mechanism comprises: a syringe comprising a syringe body, a piston comprising a piston head sealingly closing the syringe barrel, a rod and a gripping member carried by the rod; a movement actuator for moving the plunger in two opposing directions along the axis of movement of the piston in the syringe body, the movement actuator comprising a movement member and a locking device for locking the gripping member, capable of switching from an open configuration for receiving the gripping member to a closed configuration for immobilizing the gripping element in which the gripping member is secured in translation with the movement member in the two opposing movement directions.

A droplet dispenser comprises a chamber (3) with a fluid inlet valve (2) and a fluid outlet valve (4). The chamber (3) is arranged such that the volume of the chamber may be varied in use to cause fluid to be alternately drawn in to the chamber (3) through the inlet valve (2) then subsequently expelled from the chamber through the outlet valve (4) to dispense a droplet. The droplet dispenser is capable of dispensing from an open reservoir and one may change the dispensed drop volume simply and easily. The droplet dispenser can also handle liquids which are normally seen as difficult to dispense, such as cyanoacrylate adhesives.

An automated pipetting system includes a pipettor. The pipettor includes a pipetting channel, a first plunger mechanism operable to change a pressure in the pipetting channel to aspirate or dispense a liquid, and a second plunger mechanism operable to change the pressure in the pipetting channel to aspirate or dispense the liquid.

An injection device includes a cartridge configured to hold a volume of fluid, the cartridge having a proximal end and a distal end through which the fluid is dispensed; a stopper disposed in the cartridge and configured to move from the proximal end toward the distal end to cause the fluid to be dispensed through the distal end of the cartridge; and an electronic device disposed at the distal end of the cartridge, the electronic device including an emitter configured to transmit a signal toward the stopper, a receiver configured to receive reflections of the signal from the stopper, and a controller configured to wirelessly transmit data related to a position of the stopper in the cartridge.

Shown and described is a device (100) for dosing and/or preparing a mixture of substances, in particular a medium or a buffer, the device (100) comprising: at least one first container (102), which is designed to receive at least one solid component, at least one first dosing device (104) for dosing the at least one solid component, the first dosing device (104) being connected to or can be connected to the first container (102), at least one fluid connection (110, 110′) to connect to at least one second container (103, 103′), which is designed to receive at least one fluid, and/or a fluid line for supplying a fluid, and at least one second dosing device (108, 108′) for dosing the at least one fluid, the second dosing device (108, 108′) being connected or connectable to the second container (103, 103′) or to the fluid line, respectively. the fluid line, wherein the at least one second container (103, 103′) and/or the at least one second dosing device (108, 108′) are replaceable and are developed as disposable articles, and/or wherein the at least one first container (102) and/or the at least one first dosing device (104) are replaceable and are developed as disposable articles.

A distribution assembly for product delivers and deposits a precise quantity of product on a support. The assembly includes a cylinder, a piston, displaced in the cylinder by an actuator, a route for taking in the product, an ejection head with a slide valve movable between a first closed position and a second open position, and an outlet nozzle, a preparation chamber, a transfer passage, connecting, selectively the preparation chamber with the outlet nozzle. When the cylinder comes towards the support, the physical contact with the support moves the slide valve from the first position to the second position and triggers delivery of the product, pushed by the piston, via the transfer passage. When the piston arrives at the forward end of range, the piston moves the slide valve from the second to the first position, closing the passage for the product via the transfer passage.

The present invention relates to a metering container (100-1, 100-2) for metering a viscous material component (103-1, 103-2), comprising a piston (105-1, 105-2) for pressing the material component (103-1, 103-2) from a storage container (111-1, 111-2) into a metering chamber (107-1, 107-2); and a metering plunger (109-1, 109-2) for indicating a quantity of the material component (103-1, 103-2) in the metering chamber (107-1, 107-2), via which the material component (103-1, 103-2) can be dispensed from the metering chamber (107-1, 107-2).

A valve assembly for a dose filling machine having a valve body, a rotor and a first end seal assembly. The valve body has a main supply bore, a rotor bore, an upper rotor piston bore, and a side rotor dispensing bore. The rotor is rotatably positioned in the rotor bore. The first end seal assembly comprising a first end rotor seal engaging the valve bore and the rotor. A first end inner plate overlies the first side of the valve body and the first end rotor seal. The first end outer plate includes a bearing positioned within an opening thereof. A transverse slot extends from the opening to an outer edge so that a leak beyond the first end rotor seal proceeds through the transverse slot away from the bearing.
