This pipette tip includes: a first part having an outer diameter which increases gradually from a distal end side toward a proximal end side; a second part in which a taper angle of an outer surface of the second part is smaller than a taper angle of an outer surface of the first part; a third part in which a taper angle of an outer surface of the third part is larger than the taper angle of the outer surface of the first part; and a fourth in which a taper angle of an outer surface of the fourth part is smaller than the taper angle of the outer surface of the third part.

An assembly (3) for an ergonomic sampling pipette including a control rod (10) at the end of which is arranged a control button (12) for controlling the movement of the control rod (10) along a longitudinal axis (18) thereof, the button (12) having a pressure surface (11) for receiving the thumb of an operator. The pressure surface (11) of the control button (12) is movable such as to be able, during operation, to assume multiple angles relative to the longitudinal axis (28) of the control rod (10).

A method of attaching a tip to a pipette, which is executed in a robot system, includes: making an end effector of a robot hold a pipette; bringing a vicinity portion of a distal end of the pipette into contact with or close to an edge of an opening formed in a base of a tip while tilting an axis direction of the pipette by a predetermined angle with respect to an axis direction of the tip; attaching the tip to the pipette by inserting the distal end of the pipette and the vicinity portion of the distal end of the pipette into the tip while raising the pipette such that the axis direction of the pipette is aligned with the axis direction of the tip; and separating the pipette and the tip attached to the pipette from the predetermined spot.

The invention is concerned with improvements in the technical field of pipettes. For this purpose, a pipette (1) with a base body (2) and a handle (3) is proposed, wherein a thermal insulation (5) is formed or arranged between the handle (3) and the base body (2) of the pipette (1) (see FIG. 1).

A liquid contact step including injection of liquid into a flow path using a pipette chip and suction of liquid from the flow channel is performed multiple times, and a predetermined reaction is thereby performed inside the flow channel. In at least one liquid contact step, a first suction is performed in which liquid is suctioned in a state in which the pipette chip and the bottom of a liquid injection section are in contact or in close to each other. Meanwhile, in at least one liquid contact step, a second suction is performed in which the liquid is suctioned in a state in which the pipette chip and the bottom of the liquid injection section are more separated than in the first suction.

A multiple-antenna positioning system with a single drive element, providing reduced weight and complexity over systems that have a drive element for each antenna. In certain examples, each antenna can be coupled with a rotating spindle, with each antenna spindle being coupled with a pair of link arms. By driving a single drive spindle, each of the antenna spindles in the system can be rotated by the associated pair of link arms. The link arms can have an adjustable length, such as through a turnbuckle mechanism, to reduce backlash in the system, and in some examples can apply a preload to the system. By reducing backlash, the multiple antenna positioning system can have improved responsiveness to a rotation of the single drive element, as well as improved stability of the positioning of each antenna when the drive element is held in a fixed position.

A pipette is described which includes a piston for aspirating liquid into and dispensing out of a container in the pipette. The pipette is provided with at least one tracking element which is able to count the magnitude of some variable or variables relating to the amount of use of the pipette, at least one operating device for creating a limit magnitude for each variable, and for giving information when the limit value is exceeded. Thus, the user may, for instance, be warned when he may be exposed to high workload stress possibly causing injuries.

The disclosure provides an attachment structure of a pipette and a fluid injecting attachment, which includes a first cylindrical hole into which a tip end portion having a tapered shape of the pipette is inserted, on one end side of an attachment main body, and a second cylindrical hole that is communicated with the first cylindrical hole and out through which fluid inside the pipette flows, on the other end side, and a step portion between the first cylindrical hole and the second cylindrical hole due to the second cylindrical hole being formed with a smaller diameter than the first cylindrical hole, the tip end portion of the pipette is inserted through the first cylindrical hole, and while the tip end portion is inserted, the second cylindrical hole has a crush allowance farther toward a tip end side than the tip end portion.
