Abstract: The present invention relates to a sampling device for sampling a body cavity, in particular for sampling the vagina and/or cervix. The sampling device comprises a tube having two open ends, a sample-collecting member and a plunger. The plunger is inserted in the tube, with the distal plunger end protruding from the distal tube end, and carries the sample-collecting member at the proximal tube end. The plunger is displaceable in the proximal direction in the tube from a retracted introduction position into an extended sampling position. In the introduction position, the sampling member is situated inside the tube and protrudes from the tube in the sampling position.

Abstract: A product dispensing apparatus including a reservoir module, a dosing module and a dose setting member. The reservoir module includes a front casing section, a block, a first connector, a piston, and a piston rod moveable in a dispensing movement and against the dispensing movement, and including a return block engageable with the block, wherein engagement between the block and the return block prevents the piston rod from moving against the dispensing movement. The dosing module includes a rear casing section, including a second connector which is engageable with the first connector to form a detachable connection between the reservoir module and the dosing module, and a dosing and drive device. The dose setting member engages the piston rod such that it is moveable together with and in the same direction as the piston rod during the dispensing movement and is moveable relative to the piston rod against the dispensing movement.

Abstract: The present invention relates to a device for manually metering liquids, for example a pipette or a metering button. The device comprises a joint forming a seal between a hollow cylinder and a piston housed inside the cylinder, the piston being moved vertically so as to suck in or expel the liquid. During the metering operation, the joint remains fixed with respect to the movement of the piston and comprises parts formed by portions having dedicated geometric and mechanical characteristics which make it possible to locally optimize the functions of sliding, sealing and fastening in the cylinder.

Abstract: A system for titrating liquids, with a syringe or tip, comprising a holding device and at least one tag and a metering equipment, comprising an additional holding device for holding the syringe or tip on the holding device, a reading device for reading the tag of the syringe or tip held by the additional holding device, a driving device having a motor, which is detachably coupled with a plunger of the syringe when the same is held by the additional holding device, or which is coupled with a plunger which is arranged in a cylinder which is coupled with the tip via a fluid conduit, when the same is held by the additional holding device, an operating device for operating the metering equipment and a control device, connected with the operating device, the reading device and the driving device, which controls the movement of the plunger depending of the tag of the inserted syringe or tip.

Abstract: A light beam guided liquid delivery device for tracking the placement of a sample by a liquid delivery device into a receptacle like a milliliter or microliter scale tube, or a microtiter plate, includes a liquid delivery device and a light beam generator. The light beam generator may be positioned on the outside or inside of the liquid delivery device. The light beam generator may be adapted to shoot a light beam below the tip of the liquid delivery device, whereby, a user may track the placement of the tip of the liquid delivery device via the light beam.

Abstract: Systems and apparatus for mixing, cooling, and distributing multiphase fluid mixtures within a reactor, wherein reactor internal apparatus of the present invention provides not only improved fluid mixing and distribution to each underlying catalyst bed surface, but also offers other advantages including: decreased mixing tray height; easier maintenance, assembly and disassembly; and decreased amounts of fabrication material. In an embodiment, fluid may be evenly distributed to a catalyst bed from a fluid distribution unit comprising a nozzle tray including a plurality of nozzles, wherein the nozzles include at least one liquid inlet disposed tangentially to an inner surface of the nozzle.

Abstract: This invention relates to plunger operated liquid dispensers, such as hand held pipettors, which are used to portion liquids. Specifically the invention relates to a reliable removal of a liquid from the liquid dispenser. According to the invention the plunger of the liquid dispenser is arranged into a speeded up movement while removing the liquid. This change in speed is preferably sudden.

Abstract: A micropipette usable for producing a biochip inclusive of DNA micro arrays capable of arraying and fixing droplets of a micro-volume on a substrate in a high density includes a main body, at least one cavity for storing a sample, at least one ejection port, a piezoelectic/electrostrictive element mounted on the outer surface of the main body, and at least one sample inlet port for supplying sample from the outside. A sample that is temporarily stored in the cavity is discharged from at least one ejection port, by virtue of the movement of the piezoelectric/electrostrictive element, to outside of the micropipette via a through hole in a nozzle portion formed in the pipette main body. The nozzle portion through hole has three or more projection radially protruding from the center of the through hole and having a specific shape.

Abstract: A repetitive pipette wherein a rack shaft (23) vertically and movably provided in a pipette body (1) is connected to a plunger (43) of a syringe unit (41), and a vertically movable and pivotable pawl member (16) repetitively moves downward and meshes with the rack shaft (23) to feed the plunger (43) downward by a predetermined feed pitch at each time, thereby effecting repetitive pipetting, and wherein the predetermined feed pitch for the rack shaft (23) can be variably set by a pipetted quantity variably setting device. A vertically movable push button (2) is provided on the pipette body (1). A rotary control knob (3) for variably setting a pipetted quantity is provided in coaxial relation to the push button (2) so as to be vertically movable together with the push button (2) as one unit and rotatable relative to the push button (2). A pawl retaining member (12) for retaining the pawl member (16) is vertically movable together with the push button (2) as one unit.
