Abstract: A pipetting apparatus and method capable of detecting a liquid within an intermediate section of a pipette tube of the pipetting apparatus. The intermediate section is located between an upper section of the pipette tube at which a first electrode is arranged and a lower section at which a second electrode is arranged. The first and second electrodes form a measurement capacitor and are operationally connected to an impedance measurement unit, which is adapted to detect whether liquid, such as a portion of a sample liquid or system liquid, is present within the intermediate section based on the measured impedance or change of impedance, e.g. an increase of the capacitance and/or a decrease of the resistance, of the measurement capacitor caused by a presence of the liquid within the intermediate section.

Abstract: A mixing apparatus containing a drive unit having a drive and a shaft that is pivotable about a pivot axis and is operatively connected to the drive. A pivotable receptacle is arranged on the shaft, where the pivot axis is oriented essentially horizontally, and the pivotable receptacle has a base plate and at least one retainer spaced therefrom, and the pivotable receptacle is configured in such a way that holders for containers can be inserted between the base plate and the at least one retainer in the direction of the pivot axis.

Abstract: A mixing apparatus, comprising a drive unit (1) with a drive (10) and a shaft (11) which is pivotable about a pivot axis (A) and which is operatively connected to the drive (10), a pivot receptacle (2) which is arranged on the shaft (11), wherein the pivot axis (A) is substantially horizontally aligned, wherein the pivot receptacle (2) comprises a base (20) on which receptacles (21, 22) are provided which extend away from the base (20) and into which holders (3) for containers (7) are insertable.

Abstract: A hollow needle for piercing a closure of a sample vessel, wherein the hollow needle has a cylindrical hollow profile extending along a longitudinal axis and having a tip at a first end thereof, where the hollow needle has a first section that has a tip and a second section that has a larger diameter than the first section, and a transition between the first section and the second section has at least one cutting edge that extends from the first section to the second section.

Abstract: Laboratory table with front and opposite rear frame parts, has replaceable tabletop elements positionable thereon. In a first variant, the laboratory table further has detent openings at regular distances on the front and/or rear frame parts, defining a modular grid. Each opening can receive a detent bolt of a modular tabletop element, each element having at least two detent bolts for the insertion into one of the detent openings. In a second variant, each tabletop element has at least one detent opening on a front and/or rear side of the tabletop element, for insertion of a detent bolt. The front and/or rear frame part of the laboratory table have detent bolts arranged at a regular distance defining a modular grid, each one of the detent bolts being for insertion into one of the detent openings of the tabletop elements positioned on these front and rear frame parts.
