摘要:
A serological pipet for use with liquid handling may include a tip and a mounting portion with at least two sections with substantially circular cross-sections configured to fit into a pipet controller holder, the mounting portion may include a porous filter. The pipet may also include a tubular shaft with permanently marked volume indicating graduation marks. The tubular shaft may connect the tip and the mounting portion. A first section of the at least two sections and a second section of the at least two sections may have different diameters and a distance between the first section and the second section may be dimensioned to inscribe a cone having an angle of 11 degrees plus or minus 5 degrees. The tip, the mounting portion, and the tubular shaft may be made out of plastic resin.

The invention relates to a control button (12) for a manually actuated sampling pipette, the button comprising lower and upper parts (24a, 24b), one of which is equipped with a force sensor (31) and the other with an actuating member (30). In the vertical position of the button, in a state not subjected to a force, not only does the member (30) ensure that the upper part is retained axially on the lower part (24a), but these parts also define a circular axially retaining connection (42) therebetween, the circular connection exhibiting an axial clearance (47) configured such that, when a pressure is exerted on an off-centre action zone (102a) by the thumb of an operator, the axial clearance (47) is taken up in this zone (102a), while the connection (42) retains a reaction zone (102b), arranged diametrically opposite the action zone (102a), axially and locally relative to the lower part (24a).

The present invention relates to an automated sensor calibration system and method for calibrating a gas sensor in-situ in a controlled atmosphere workstation. The system comprises a control means for automatically controlling the calibration system; an enclosure means movable between a first position and a second position; and a drive mechanism, operable by the control means, for moving the enclosure means between the first position and the second position. In the first position, the enclosure means is arranged in a spaced relationship from the sensor such that a sensing head of the sensor is exposed to the controlled atmosphere of the workstation. In the second position, the enclosure means is arranged in engagement with at least one surface so as to define a calibration chamber and enclose the sensing head in the calibration chamber.
