Description
Technical field
The present invention relates to that a kind of pipette is supporting moves liquid suction tool, particularly relate to pipette servicing unit.
Background technology
Pipette in the lab for liquid configuration is included in the interior moveable piston of cylinder (cylinder barrel), and described piston is used for sucking in tip by liquid and being distributed from tip by liquid according to the pipette functions selected, and described tip is connected on cylinder unit.The usual adjustable of described liquid volume.Also the electronic pipette that its piston is activated with the control system be associated by motor is had.The user interface that electronic pipette has control system and is associated, for setting the pipette functions of particularly volume and other necessity, and for sending the order for executable operations.What cost was the cheapest is glass pipet, compound rubber ear ball imbitition, wherein has segment glass pipette to need to blow operation soon.Existing liquid-transfering device as Chinese invention patent " controllable pipette ", the patent No. 200580005913.1, this invention relates to a kind of controllable pipette, and pipette is included in the piston by electromechanical actuation in cylinder; Control system, control system allows piston to move according to that be made up of several step, given pipette functions; For selecting the setting key expecting pipette functions and related setting; The switch of start-up performance step when depressed; And display screen.Control system comprises change function, and the startup changing function makes the function of selection can be changed in its process operated.When changing function and can being activated, this is displayed on the screen, and by pressing given setting key, changing function can be activated.But this invention complex manufacturing technology, cost is higher.
Summary of the invention
The object of the invention is to for prior art provide a kind of with low cost, replaceability strong, blowing operation, compatible good pipette servicing unit can be simulated.
The present invention solves the problems of the technologies described above adopted technical scheme: pipette servicing unit, comprises the tubular cylinder that inner side is provided with movable rod, wherein: one end of movable rod has the piston that can be slidably matched with tubular cylinder inner wall; What the other end of movable rod was shaped with evagination pushes away handle; Movable rod has the inner chamber of hollow, and this inner chamber be provided with can along the depression bar of movable rod axially reciprocating; Depression bar has the glue head matched with lumen openings near one end of piston.The process that movable rod is upwards mentioned, can replace the suction operation of prior art middle ear ball.Further, after glass pipet is drawn onto required amount of liquid, operating personnel stop action the lift operation of connecting rod, then press down-pressed pole handle.Namely substitute prior art middle ear ball bleed air operation by down-pressed pole handle, pipette starts to release the liquid sucked before this.When the liquid of pipette is about to flow to end, if this device connect be blow pipette soon, then according to unclamping depression bar handle opportunity, and again quick by down-pressed pole handle to blow last drop of liquid in pipette, namely substitute manually with the operation that mouth is blown, avoid the pollution risk that therefore sample brings.
For optimizing technique scheme, the measure taked also comprises: one end of movable rod has the piston that can be slidably matched with tubular cylinder inner wall; What the other end of movable rod was shaped with evagination pushes away handle; Movable rod has the inner chamber of hollow, and this inner chamber be provided with can along the depression bar of movable rod axially reciprocating; Depression bar has the glue head matched with lumen openings near one end of piston.The process that movable rod is upwards mentioned, can replace the suction operation of prior art middle ear ball.Further, after glass pipet is drawn onto required amount of liquid, operating personnel stop action the lift operation of connecting rod, then press down-pressed pole handle.Namely substitute prior art middle ear ball bleed air operation by down-pressed pole handle, pipette starts to release the liquid sucked before this.When the liquid of pipette is about to flow to end, if this device connect be blow pipette soon, then according to unclamping depression bar handle opportunity, and again quick by down-pressed pole handle to blow last drop of liquid in pipette, namely substitute manually with the operation that mouth is blown, avoid the pollution risk that therefore sample brings.The inner chamber of movable rod is provided with spacing ring near the position pushing away handle; Depression bar has depression bar handle near the one end pushing away handle; Depression bar is provided with spring between spacing ring and depression bar handle.Spring between spacing ring to depression bar handle is used for the reciprocating motion of depression bar in auxiliary relevant operating process.The interface of cylinder is provided with rubber adapter.This rubber adapter is for fitting snugly in the base portion of glass pipet.
Because the one end that present invention employs movable rod has the piston that can be slidably matched with tubular cylinder inner wall; What the other end of movable rod was shaped with evagination pushes away handle; Movable rod has the inner chamber of hollow, and this inner chamber be provided with can along the depression bar of movable rod axially reciprocating; Depression bar has the glue head matched with lumen openings near one end of piston.The process that movable rod is upwards mentioned, can replace the suction operation of prior art middle ear ball.Further, after glass pipet is drawn onto required amount of liquid, operating personnel stop action the lift operation of connecting rod, then press down-pressed pole handle.Namely substitute prior art middle ear ball bleed air operation by down-pressed pole handle, pipette starts to release the liquid sucked before this.When the liquid of pipette is about to flow to end, if this device connect be blow pipette soon, then according to unclamping depression bar handle opportunity, and again quick by down-pressed pole handle to blow last drop of liquid in pipette, namely substitute manually with the operation that mouth is blown, avoid the pollution risk that therefore sample brings.Thus the present invention have with low cost, replaceability strong, blowing operation, compatible good advantage can be simulated.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation.
