A linear motor, comprises at least one stator device () with a plurality of permanent magnets (--) of different polarity and with at least one carrier rail (), and at least one rotor device () with at least three electrical coils () and with at least one supporting means (), which can be or which is supported on the carrier rail () of the stator device (), wherein the rotor device () and the stator device () are moveable to and fro with respect to each other along a movement direction (FR) defined by the carrier rail () by interaction of magnetic fields of the permanent magnets (--) with the magnetic fields of the coils (), through which current flows if required, wherein the stator device () is formed from at least one stator module (--), wherein the stator module (--) is configured such that a stator device () with two or more consecutively arranged stator modules (--) can be formed, and wherein at the stator module (--) at least one measurement track (---) scannable by a sensor unit (--) of the rotor device () is provided, which runs substantially parallel to the movement direction (FR). On the rotor device () at least two sensor units (--) scanning the measurement track (---) are provided, which are arranged along the movement direction (FR) of the rotor device () in a distance (SA) such that if the rotor device () is arranged on a connection point (, L) between two stator modules (--) the respective measurement tracks (---) of the adjacent stator modules (--) are scannable by one of the two sensor units (--), respectively.

The invention relates to a metering device () comprising a guide tube (), a piston () inserted displaceably in the guide tube (), an actuating assembly () for exerting a force on the piston () in order to displace the piston () in the guide tube (), and a chamber () for receiving a medium to be metered (), said medium to be metered () can be aspirated or dispensed according to a displacement of the piston (), the actuating assembly () being equipped for a magnetic interaction with the piston ().

Metering device and metering method

A position detecting device for detecting a positional relationship between a first component and a second component includes a marking arrangement which is provided on the first component and has an absolute track and an incremental track. The absolute track has a plurality of absolute markings from which a binary absolute code sequence can be read, and the incremental track has a plurality of incremental markings which are associated with the absolute markings and from which an alternating incremental sequence can be read. A sensor arrangement provided on the second component and is configured to scan the absolute markings and the incremental markings. The absolute code sequence is formed from a first and a second De Bruijn sequence of order N which follow one another.

A process for hydrophobically coating a pipette tip by wetting at least regions of the inside of the pipette tip with a wetting solution, the process including: providing a holding cavity other than the pipette tip on a pipette device, immersing the holding cavity in the wetting solution, aspirating wetting solution into the holding cavity, connecting the pipette tip to the holding cavity, dispensing the aspirated wetting solution from the holding cavity through the pipette tip so as to rinse a pipetting fluid holding chamber portion inside the pipette tip, and evaporating solvent contained in the wetting solution.

Process for hydrophobically coating a pipette tip

Processes for hydrophobically coating a pipette tip by wetting at least regions of the outside and inside of the pipette by with a wetting solution are disclosed. Such a process may include coupling the pipette tip to a fluid pressure source having variable fluid pressure, immersing the coupled pipette tip in the wetting solution, aspirating wetting solution into the pipette tip, dispensing the aspirated wetting solution, and evaporating solvent contained in the wetting solution.

A pipette device including a metering liquid receptacle designed to be filled, at least in part, with working fluid and which has a pipette opening as a first tapering of cross-section of flow, a pressure change device which is designed to change the pressure of the working fluid in the metering liquid receptacle, and a throttle point in a pipette duct designed to be filled with working fluid as a further tapering of cross-section of flow. The throttle point is arranged fluid-mechanically between the metering liquid receptacle and the pressure change device and is dimensioned in such a way that a ratio of a flow resistance of the pipette opening for dispensed metering liquid to a flow resistance of the throttle point for working fluid, which flows through the throttle point when the metering fluid is dispensed, is less than 0.5.
