The present invention provides an attachment or extension for pipettes and pipette tips. The attachment comprises separation materials which are preferably suitable for isolating nucleic acids from liquids. The separation materials are present in the form of a filter disc in a holder which only slightly increases the pipette volume and thus generates little dead volume.

A hydrodynamic clutch device used to establish and to release a working connection between a drive and a takeoff is disclosed. The device includes a housing capable of rotating around an axis of rotation, the housing containing a torus space, which forms a torus volume (TV) with a pump wheel and a turbine wheel, and a clutch space, which forms the boundaries of the clutch volume (CV) and which encloses a mechanical transmission circuit including a bridging clutch designed with a torsional vibration damper During the course of the minimum resting phase of the housing, the fluid which is distributed throughout the housing during the operating state decreases from a total volume comprising at least the torus volume (TV) and the clutch volume (CV) to a resting volume (RV), which is located at least essentially underneath the axis of rotation as a result of the force of gravity. A volume reduction arrangement is provided to the housing to reduce the clutch volume (CV) versus the resting volume (RV).
摘要:
An actuating drive for transmitting drive torque to a power takeoff, comprising a drive unit; a braking device comprising a cylindrical surface; and a wrap spring having a plurality of turns which are concentric to the cylindrical surface, a pair of ends, a first actuating area on one of the ends, and a second actuating area on one of the ends. When the drive unit exerts a drive torque in a first direction, the first actuating area is nonrotatably connected to the drive unit, the turns undergo a diameter change away from the cylindrical surface, and the second actuating area is nonrotatably connected to the power takeoff for transmitting drive torque. When the drive torque is interrupted, the turns undergo a diameter change toward the cylindrical surface and frictionally engage the cylindrical surface to block transmission of restoring torque from the power takeoff to the drive unit.

A torsional vibration damper in a gearbox housing, equipped with an input part, which is connected to a drive and acts on a first damping unit; and an intermediate part. The intermediate part, in its first capacity, acts as the output of the first damping unit and has drive-side drive elements to interact with the first damping unit, and in its second capacity, acts as the input of a second damping unit and has takeoff-side drive elements to interact with the second damping unit. The torsional vibration damper further has an output part, which is in working connection with the second damping unit and which is designed to accept a takeoff. The takeoff-side drive elements of the intermediate part, the second damping unit, and the takeoff are mounted in a torque-transmitting space of a clutch device, which space is provided with at least one inlet and at least one outlet.
摘要:
Device for the isolation of nucleic acids from a liquid sample by introducing the liquid into the device through an inlet opening and passage of the sample through a nucleic acid binding material and discharging of the resulting liquid through an outlet opening, wherein the nucleic acid binding material is inserted through the outlet opening during the manufacture of the device and the outlet opening is narrowed in order to hold the material. The device is particularly simple and reliable to manufacture but yet ensures that nucleic acids can be isolated without contamination.
摘要:
A capacitive linear or rotary transmitter for controlling and positioning displaced objects by measuring the displacement, angle or speed of the displaced object is formed, in one embodiment as a rotary transmitter, by two mutually opposed stators defining a reciprocal spacing, their gap having rotatably arranged in it a rotor which is rotatably coupled to a spindle which is coupled to the displaced object. Capacitive values varying during the rotation of the rotor may be measured in the air gaps produced in each case between one stator and the rotor, and the other stator and the rotor. To attain a superior degree of precision and resolution, coatings are so arranged on the rotor and the stators, as to produce at least two concentric annular areas, of which one area forms the measurement track of a coarse measuring system and the other area forms the measurement track of a precision measuring system. The digitally determined values of the coarse measuring system are so combined with the values of the precision measuring system as to yield an unequivocally defined absolute value for the angle of rotation. This is attained by the fact that the coupling capacitances generated by mutually associated coatings of the rotor and stators follow a course during the rotary displacement of the spindle which is sinusoidal in parts and that by addition of several reciprocally displaced capacitance graphs which extend sinusoidally in parts and are provided with different prefixes, an approximately purely sinusoidal capacitance graph is generated with a cycle depending on the number of measurement tracks.
