An integrated nucleic acid processing apparatus includes a first operation area, a second operation area and a separation wall. The first operation area includes multiple carrying boards for placing objects and reagents for processing nucleic acids in samples, and multiple operation modules for performing operations of nucleic acid processing. The second operation area includes two extraction regions for respectively performing nucleic acid extractions. The separation wall separates the first operation area from the second operation area and includes two openable door sheets spatially corresponding to the two extraction regions. Nucleic acid extraction plates can be moved from the first operation area to the second operation area by means of the carrying boards as the two openable door sheets are opened, and be isolated in the second operation area for performing nucleic acid extractions as the two openable door sheets are closed.

A dispenser for taking up and discharging fluid volumes which has an exchangeable piston-cylinder unit. The dispenser has a housing and a device for incremental distance measurement that, when there is relative movement between the piston and the cylinder, the distance traveled by the piston relative to the housing can be determined incrementally. The dispenser has a piston actuation member which can be releasably connected to the piston moving the piston in order to take up and/or discharge fluid volumes. The dispenser has a position determining device which has a first position element and a second position element. The first position element is fixed in or on the housing of the dispenser. The second position element is coupled so as to be able to move with the piston actuation member. The position determining device is for continuously sensing the position of the second position element.

The present invention relates to an automatic real-time quantitative amplification system which can perform analysis of various biological samples, and more particularly to an automatic real-time quantitative amplification system in which a plurality of decks for respectively accommodating biological samples are put in a deck storing/transferring device, whereby it is possible to automatically analyze an amount or existence of a target substance containing a target nucleic acid in the biologic sample, such as a particular gene, a particular, a particular pathogenic bacterium and a particular protein, by amplifying the target nucleic acid purified by some processes of purification, purification after culture, or purification after reaction of the target substance contained in the biological sample and then checking an amount of the amplified target nucleic acid.

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.

The invention relates to a pipetting apparatus for pipetting laboratory samples into a pipetting container which can be connected to the pipetting apparatus, which pipetting container is in particular designed according to the invention, comprising a container side and a first connection section, by means of which the pipetting container can be connected to the pipetting apparatus, and comprising an information carrying device with at least one information section, which carries information, on this container side; the pipetting apparatus comprising an electric information reading device, by means of which information contained on the information reading device can be read when the pipetting container is connected to the pipetting apparatus, and which comprises at least one electric sensor device, which comprises at least one sensor section, opposite to which a measuring space is formed, wherein the sensor device is configured to read the information content of at least one information section when the latter is arranged in the measuring space.
