Abstract: A mechanical pipette comprising: a. a manually drivable mechanical unit for pipetting liquids, b. at least one sensor for detecting operating and/or performance data, c. an operating unit, and d. a display unit, e. wherein a device module comprises the mechanical unit for pipetting, the sensor and operating unit, f. a display module physically separate from the device module completely or partially comprises the display unit, and g. means for wireless communication between the device module and the display module.

Abstract: 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.

Abstract: 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.

Abstract: The present invention relates to a pipette having: a rod-shaped handle body in which a drive unit is arranged for a displacement unit having an operating element in the top end, and having a seat for a pipette tip or syringe in the bottom end, wherein the handle body has a front grip surface that is approximately straight in the bottom part of the handle body in a vertical sectional plane through the handle body, and curves across the handle body toward a thumb rest in the top part of the handle body above the area that comes into contact with the surface of the hand, and the operating element actuatable with the thumb is arranged in the thumb rest.

Abstract: 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 (11, 110) is dimensioned so as to permit the frame to be deposited on the microtitration plate (13), such that the mat (12, 120) 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.

Abstract: 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.
