The invention relates to a pipette auxiliary system for supporting manual pipetting or dispensing of a plurality of samples of a sample-holding arrangement, in particular a microtiter plate. The pipette auxiliary system according to the invention supports the manual pipetting or dispensing of a plurality of samples in a working position of a sample-holding arrangement, the pipette auxiliary system comprising: a base apparatus comprising a positioning device which is designed to position the sample-holding arrangement in the working position inside a positioning space of the base apparatus, said positioning space being opened at least along a plane for the pipetting; the sample-holding arrangement which has a plurality of sample holders; a measurement arrangement comprising a plurality of measurement elements which are positioned at least in the working position underneath this plane and using which the occupancy state of at least one sample holder can be detected in the working position; and an output device or a light arrangement using which the sample-holding arrangement can be illuminated in accordance with this occupancy state of this at least one sample holder.

The present invention relates to system and method for inventory management, more specifically to the tracking of use and/or consumption of tangible products at a user's location. In accordance with the invention, consumption data is determined and analyzed. Consumption data may include time-referenced and/or quantitative data about the tangible product, so that the origin/supplier is informed about the consumption behavior of the user.

System and method for determining the use or consumption of tangible prodcuts and for delivery according to use or consumption

The invention relates to a positioning device for a sample distribution apparatus, such as a pipetting apparatus, providing a first part, at which a sample transport device can be arranged, a second part, at which a sample holder can be arranged, wherein the first part and the second part are arranged moveable in relation to each other between a first position and an adjusted target position of the first and second part for performing a positioning motion, such that a sample can be conveyed towards the sample holder by the positioning motion. The automated change of the target position assists for achieving an error-free positioning and sample distribution. A corresponding method for the automatical change of a position of a first part relative to a second part using the positioning device, is also claimed.

Pipette

A covering for apertures of reaction receptacles formed in a microtitration plate, including a hermetic, elastically deforming mat or foil, a frame, and connecting elements. The mat or foil, upon planar deposition on the microtitration plate and following compression, seals the apertures. The connecting elements are fitted onto at least one of the mat or foil and frame and detachably secure the mat or foil to the frame while creating a tension in the mat or foil implementing the connection. The frame () is dimensioned so as to permit the frame to be deposited on the microtitration plate (), such that the mat () or foil rests in a planar manner on the microtitration plate, and such that the frame is accessible from above to a pressure and/or heat applying device.

Covering for the apertures of reaction receptacles constituted in microtitration plates

A liquid proportioning method using a chamber for a gas and a reception volume connectable thereto for a liquid with an aperture to the environment, wherein a desired volume is predetermined for the liquid to be taken up by the reception volume, a chamber negative pressure is determined which has to exist in the chamber to cause the desired liquid volume to be taken up in the reception volume after the aperture is dipped into the liquid and the chamber is connected to the reception volume, the chamber negative pressure is produced in the chamber, the reception volume dips its aperture into the liquid, and the chamber is connected to the reception volume and the desired volume of the liquid is taken up in the reception volume.
