Definitions
- the invention relates to a pipetting device for automated pipetting of chemical substances in micro-chamber arrays with a holder receiving at least one micro-chamber array and a movably attached pipetting head.
- Micro-chamber arrays consist of a large number of, for example, matrix-like arranged micro-chambers, which in the simplest case consist of a small cavity, but are also complex reaction containers composed of many individual components
- Automated pipetting devices are often used for the rapid and economical filling of small sample quantities into the individual microchambers. In doing so, ne pipette passed a short distance over the individual microchambers and a precisely metered amount, usually dissolved in a solvent, of the desired chemical substance is filled into the respective microchamber.
- the object of the invention is therefore to design a pipetting device in such a way that undesired evaporation effects are largely reduced during a pipetting process with any solvents.
- the pipetting head is attached to a plate by means of a holding device which is guided over the micro-chamber array in a sliding manner or at a short distance following the movements of the pipetting head during the pipetting process and in connection with a frame which surrounds the micro-chamber array tightly forms a closed gas space above the micro-chamber array, in which the pipetting head protrudes through a suitable opening in the plate.
- the volume available for the evaporation of the solvent is significantly reduced.
- an atmosphere saturated with solvent forms in the closed gas space, so that hardly any further evaporation takes place.
- practically no convection favoring evaporation occurs in the very thin layer above the microchamber array.
- the pipetting head can be moved vertically out of the opening in the plate.
- the pipetting head can be removed from the plate with a simple movement or automatically controlled. Refilling or replacing the pipetting head during or after a pipetting process is possible without the solvent escaping in an uncontrolled manner getting directly onto the micro-chamber array.
- the pipetting head is attached to a vertically movable holding arm, which is longitudinally displaceable on a slide along a guide rail on the plate.
- a vertically movable holding arm which is longitudinally displaceable on a slide along a guide rail on the plate.
- the pipetting head can be moved out of the filling position in the direction of a storage container which contains a sufficiently large amount of the solutions to be pipetted.
- the holding arm of the pipetting head is raised until the tip of the pipetting head is at a sufficient distance from the plate. Then the pipette head, which can now move freely, together with the holding arm, can be moved along the guide rail to beyond the edge of the plate.
- the storage container is expediently located there, so that the solvent can be automatically taken up by the pipetting head.
- the automatic refilling leads to a further reduction in evaporation due to the time savings that can be achieved thereby.
- the plate is so large that, even in the case of an opening of the plate positioned beyond the frame next to the micro-chamber array, the frame tightly surrounding the micro-chamber array is completely covered. If the pipetting head is raised on the plate for filling, the gas space above the micro-chamber array is no longer completely closed due to the remaining opening.
- the plate In order to keep the gas space closed in this case too and thus to prevent evaporation effects that are otherwise favored, the plate is moved to the side until the opening in the plate is beyond the frame that closely surrounds the micro-chamber array. The pipetting head can then be lifted vertically out of the opening of the plate without the gas space, which is still closed, being connected to the surrounding atmosphere.
- a trench-like groove receiving a liquid volume is arranged along the frame within the closed gas space.
- a sufficient amount of the solvent also used for pipetting can be filled into this trench-like groove before the pipetting process.
- the volume of solvent filled into the trench-like groove is intended for the most effective evaporation.
- a saturated atmosphere of solvent can be made within the umringe- NEN gas space before a pipetting operation, so that evaporation of the already pipetted Lö ⁇ sungsffens is further reduced during the pipetting.
- the plate is slidably moved on a sliding support provided above the trench-like groove with a scraper edge.
- a sliding pad can be made of PTFE, for example, so that disturbing friction effects are largely avoided.
- small amounts of evaporated solvent can condense on the underside of the plate.
- a corresponding surface on the underside of the plate sweeps over the sliding support. Condensed solvent is absorbed there by the scraper edge and can drip or flow into the trench-like gutter underneath.
- the temperature of the micro-chamber array can be regulated. In this way, identical filling conditions can be guaranteed during a pipetting process and also over several filling processes. Furthermore, the evaporation behavior of the solvent already pipetted into the microchambers can be controlled via the temperature of the microchamber array.
- the temperature of the plate movable above the micro-chamber array can be regulated.
- the plate temperature due to the large contact area of the plate with the closed gas space, the plate temperature has a direct effect on the enclosed gas volume.
- the condensation of the solvent can start the underside of the plate can be largely avoided.
- a troublesome droplet formation on the underside of the movable plate can thus be avoided, so that the precisely metered volume of solvent in the microchambers is not changed unintentionally by solvent drops falling on the microchamber array in an uncontrolled manner.
- the single figure shows a section through a pipetting device for the automatic pipetting of chemical substances in micro-chamber arrays.
- a holder 3 consisting of a base plate 1 and fastening devices 2 is used to hold a micro-chamber array 4.
- a holder 3 consisting of a base plate 1 and fastening devices 2 is used to hold a micro-chamber array 4.
- a micro-chamber array 4 Around the holder 3 there is a
- a guide rail 8 is permanently attached to a plate 7 which is movably supported on the sliding support 6.
- a pipetting head 11 is attached to the holding arm 10, the pipette cannula 12 of which projects through an opening 13 in the plate 7 into a gas space 14 which is completely closed off by the micro-chamber array 4, the frame 5 and the plate 7.
- the pi Pettierkopf 11 each positioned over the micro-chamber of the micro-chamber array 4 to be filled, by moving the plate 7 together with the structures attached thereon, in particular the pipetting head 11 with the pipette cannula 12 projecting through the opening 13 of the plate 7.
- the sliding support 6 has a wiping edge 15 on the side facing the closed gas space 14 hm. Solvent condensed on the underside of the plate 7 is absorbed by the stripping edge 15 when the plate 7 is displaced outwards over the sliding support ⁇ and runs down on the inside of the frame 5 located underneath.
- Sliding pad 6 formed a trench-like groove 16.
- the condensed solvent stripped from the plate 7 collects.
- a sufficient amount of the solvent can be deposited in the gray-like channel 16 before a pipetting operation.
- the solvent gas evaporates out of this trench-like groove 16 and a saturated atmosphere in the closed gas space 14. Evaporation effects of solvent already pipetted out of microchambers of microchamber array 4 are largely suppressed as a result.
- the plate 7 which is movable above the micro-chamber array 4 is optically transparent. In order to ensure the greatest possible range of application for the pipetting device, all can be closed Gas chamber 14 directly surrounding components of the device consist of chemically largely inactive materials.
- the plate 7 is not moved over a fixed frame 5, but instead, by moving the holder 3 and frame 5 relative to a permanently fixed plate 7, the micro-chamber array 4 is positioned relative to the pipetting head 11 before each pipetting process ,
