Abstract: A pipette tip made of plastic includes a tubular body having an inner circumference and an outer circumference. The tubular body includes a bottom end defining a bottom opening structured to enable passage of a liquid and a top end defining a top opening that clamps onto a mount of a pipetting device. A seat region for the mount is positioned proximate to the top opening and on the inner circumference of the tubular body. A plurality of flattenings extend in an axial direction on the outer circumference proximate to the top opening. The tubular body defines a contour of an arc polygon in a cross-section through the flattenings on the outer circumference.

Abstract: A control arrangement and method for controlling a sensor-free diaphragm pump are disclosed. The control arrangement comprises a control-fluid inlet for connection to a first control-fluid reservoir having a pressure level which is elevated in relation to a reference pressure, a control-fluid outlet for connection to a second control-fluid reservoir having a pressure level which is reduced in relation to a reference pressure, a control-fluid connection for connection of a control-fluid line for the sensor-free diaphragm pump, wherein the control-fluid inlet is connected via a first proportional valve to a collecting point, and the control-fluid outlet is connected via a second proportional valve to the collecting point, wherein a mass flow sensor is arranged between the collecting point and the control-fluid connection. A control unit is in signal communication to the first proportional valve, the second proportional valve and the mass flow sensor.

Abstract: The invention relates to a pipetting device with a touch screen and a system comprising said pipetting device. The operating concept of this pipetting device provides that values of pipetting parameters can be set by a user on at least one input screen page, that actuation of the actuating element leads to the display of an output screen page and to the start of a pipetting operation defined according to the pipetting parameters, and that touching a separate input field of the output screen page leads back to an input screen page.

Abstract: The invention relates to a measurement apparatus for measuring the concentration of a gaseous substance. The apparatus comprises a light source, a light sensor, and a housing comprising at least one first housing member having a low thermal conductivity. A light path is formed from said light source to said light sensor, wherein the light path passes through a measurement region within said housing. The light source is configured to emit light with a spectral distribution such that said light is absorbed by said gaseous substance. Said light sensor is configured to receive the light emitted by the light source after it has passed through the measurement region. The first housing member comprises a thermal shielding region facing said measurement region on its one side and said light sensor on its other side, and is configured to permit the passage of light.
