Definitions
- the invention relates to a device for receiving and dispensing liquids with a plurality of piston-cylinder units, each arranged on a piston plate and a cylinder plate, wherein the liquid intake and -abgäbe by a displacement of the piston in the cylinders by means of a change in the distance of the plates a drive mechanism and a Plattenbowung perpendicular to the plate planes, wherein the volume by an upper and a lower stop, of which at least one is adjustable by means of at least one adjusting means, can be determined.
- the invention is therefore based on the object to make a device of the type mentioned with little technical effort to handle exact volumes of a larger number of piston-cylinder units suitable.
- the object is achieved in that at low demands on the surface parallelism of the plate levels during movement in the plate guide same recording and dispensing volumes of the piston-cylinder units are ensured by the fact that the attacks are designed and arranged such that the parallelism of Plates in the upper and lower stop position is achieved by means of the stops.
- the fiction, contemporary approach is that it is not necessary for the pipetting exact volumes, throughout the pipetting a uniform movement of all pistons, so to ensure a constant parallelism of piston and cylinder plate. Rather, it is sufficient for the accuracy of the recorded or dispensed volumes, if all piston-cylinder units are in exactly the same position at exactly two times: in a lower end position and an upper end position, which is ensured by the stops.
- the gap between multi-channel pipette and fully automatic systems is closed. It allows the parallel recording or dispensing of many, preferably 96 liquid samples.
- the volume is freely selectable and exactly adjustable.
- the pipetting process itself is simple and easy to learn, and is largely similar to what has been known in manual pipettes for decades.
- the stops can be designed in various ways. It is essential lent that they guarantee a parallelism of the plates, so the piston plate and the cylinder plate in the upper and lower stop position. If, for example, the piston plate moves, the cylinder plate can serve as a lower stop or carry such attacks, then only needs an upper stop to be arranged.
- This stop can itself be a flat plate or it can be two line-shaped attacks.
- each of the upper and lower stops has at least three stop points, which strike in the outer region of the moving plate. At least three points because it allows the exact location of a surface to be defined. Pipetting operations are usually carried out by means of worktops, which have an orthogonal grid and therefore a quadrangular shape. Therefore, you will also choose a square shape for the piston plate and the cylinder plate. Four stop points on the plate corners then offer themselves, whereby, of course, the mentioned three are possible.
- the stops are equipped with adjusting means for adjusting the parallelism of the stop positions. This serves both an exact initial setting and any readjustments.
- the adjustment means for the volume adjustment is designed such that the stop points of the adjustable stop are simultaneously height adjustable.
- a volume adjustment can be made by a single operation, always ensuring a parallelism of the plates in the end positions and thus exact volumes of all piston-cylinder units.
- the attachment points are adjustable by stepper motors. This can be realized by a very simple control with a single display.
- stop points can be adjusted by threaded spindles or by turning on solid threaded spindles adjusting nuts, which are moved by means of toothed belt and gears of an adjusting device simultaneously.
- This setting can be done without Load through a plate resting against a stop. If the stop or the attachment points in the direction of an adjacent plate, z. B. the piston plate, are moved, it should be expediently moved away before, so that ease and low effort is guaranteed.
- measures are also possible to ensure this, such as blocking the adjusting means or an automatic movement away of the plate at the beginning of actuation of the adjusting means for the stop.
- this adjusting device has a display device which displays the set volumes.
- Essential for the embodiments of the volume setting is that the adjusting mechanism of all forces-moderate loads, in particular of those who must apply the drive for the pipetting process, is exempt, and therefore can be achieved inexpensively high accuracy.
- the device Since the device is preferably used when one needs much more piston-cylinder units than with an 8- or 12-channel pipette, and these are arranged in a grid-like arrangement, for example, with 96 units, is a placement of the device on a worktop with as many working positions problematic. Therefore, it is proposed that the piston plate, the cylinder plate, the stops and the drive are arranged in a pipetting head, which is suspended by means of a vertical guide on a stand. Then, it is also useful if the stand has a positioning device for the positioning of the pipetting head to a pipetting serving countertop to the grid arrangement of the piston-cylinder units with the grid arrangement of the working positions on the Matching worktop. In this way, a particularly fast work is possible without the skill too high demands must be made.
- the positioning means are mounted on a turntable to sequentially match a plurality of worktops.
- the stand has a horizontal guide for the pipetting head and under the horizontal guide next to each other several positioning of worktops, positioning aids are provided for assigning the grid on the horizontal guide.
- several positioning devices are provided for worktops, which are displaceable by means of at least one horizontal guide for this, for example by sliding trays, so defined by positioning aids positions that worktops located there are the grid of the piston-cylinder units assigned , The latter possibility can also be combined with the aforementioned by extending horizontal guides for the worktops transverse to the horizontal guide for the pipetting.
- the positioning aids can each be the end stops of the horizontal guides. Thereby, the above-mentioned, often required four worktops can be positioned (see Fig. 2). Of course, other positions can be carried out if locking positions are set up between the stops.
- At least one lower stop is preferably provided. This is used to set the vertical movement down a stop position in which the desired pipetting can take place, since the correct height position for a liquid intake or Abgabäbe is given in relation to the respective worktops. Therefore, it is also appropriate that the at least one lower stop for adjusting the immersion depth in liquid receptacles of the worktops is adjustable. If, for example, a plurality of worktops are located in positioning devices under the horizontal guide for the pipetting head, it is of course possible for each positioning device to have a stop so that the correct height can be set above the respective worktops.
- the vertical guide of the pipetting head is associated with a weight compensation device, which is dimensioned such that a smooth vertical movement with little effort is possible.
- a spiral spring is particularly suitable since it has an almost linear characteristic, as a result of which the force required for the vertical movement on the whole
- the vertical guidance of the pipetting head can be associated with a high acceleration responsive fall arrest or brake. This is useful to drop down - and resulting
- the moving plate is the piston plate, so that the drive is preferably associated with the piston plate. It can then be provided that the drive spends the piston plate in its lower stop position and reset fields return it to the upper stop position. This allows a particularly simple work and prevents the piston plate can dwell in an undefined position.
- the pistons may be sealed to the cylinders by means of seals.
- seals may be formed as arranged on the piston sealing rings. But it can also be provided that the cylinder plate is divided in the horizontal direction and elastic sealing material is stored such that by means for compressing the plate members, the cylinder diameter at the sealing points are adjustable, the pistons move in the region of the sealing points.
- the sealing material may be a perforated plate of elastic material, or it may be assigned to each cylinder an annular elastic sealing element.
- the cylinders may be directly equipped with suction ports, or it is possible that at the lower end of the cylinder recordings for the attachment of Liquid receptacles, in particular of pipette tips, are arranged.
- the piston-cylinder units serve as suction devices which generate the vacuum corresponding to the suction, as well as by the downward movement blow out the liquid contained in the liquid receptacles. In this way, after an operation or before a change of the liquid to be pipetted, only an exchange of the liquid receptacles takes place.
- the receptacles for the liquid receptacles for example, tubes or pipette tips, can be provided with elastic rings, so that a secure hold and tight fit is ensured, even if the liquid receptacles or pipette tips have diameter inaccuracies.
- a force transmission which presses the pipetting head for receiving the fluid intake, in particular the pipette tips, against a positioning device in a liquid receiving carrier, in particular pipette tip carrier, or vice versa.
- the force transmission can be, for example, a transmission lever, which acts between the stator and the pipetting head, the latter against the liquid receiving carrier, in particular the pipette tip carrier.
- a liquid intake or pipette tip scraper is provided.
- This may be a lever-operated, arranged below the cylinder plate, vertically displaceable perforated plate.
- the holes must be larger than the recordings, but smaller than those of the liquid receptacles or pipette tips, in order to strip them from the recordings can.
- the lower stop is designed as a catch which defines the decisive for determining the volume stroke by aligning the plate in parallel. Thereafter, the moving plate by overcoming the holding force or actuation of an unlatching of the catch is still a little further moved to blow out any remaining liquid residue.
- a development of the device also provides that at least one latch-like intermediate stop is arranged for a portionwise delivery of the liquid absorbed between the upper and lower stops, which also causes a parallel alignment of the plates and can be overcome with increased force or actuation of a unlatching.
- One or more such intermediate stops serve the purpose that after a single liquid intake defined volumes of this liquid can be delivered successively to two or more worktops. In this way, it can be worked more efficiently, if several worktops are to be supplied with the same liquid.
- this should also be adjustable at least one latch-like intermediate stop, that also with respect to the successively discharged liquid, the volumes can be accurately determined.
