Microtitation plate

Pipette tip made from plastics with an elongate, tubular body which comprises at a lower end a pipetting aperture, at an upper end a placement aperture () for placement on a receiving shank of a pipetting device, in the vicinity of the upper end a circumferential rib along a closed curve comprising different spacings from the lower end in different contour positions, a circumferential contact region on a surface of revolution on the inner face of the circumferential rib and at least one further rib extended from at least one position of the circumferential rib at a maximum distance from the lower end as far as the upper end.

Pipette tip

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.
