Embodiment Construction

[0021] first reference figure 1 , figure 1 A manually actuated air displacement sampling pipette 1 according to a preferred embodiment of the present invention is shown. In the following description, the terms "top" and "bottom" refer to when the pipette is held upright, in or near the pipetting position.

[0022] figure 1 The pipette 1 is shown held by the hand 2 of an operator actuating the pipette with a thumb 4 to cause dispensing of previously aspirated liquid.

[0023] More specifically, the pipette 1 comprises a handle 6 as the upper body of the pipette, from which, in the pipetting position, emerges a pipetting control rod 10, at the top end of which a control rod 10 is supported. button 12, wherein the top portion of the control button 12 is used to withstand the pressure of the operator's thumb. More specifically, the button has a pressure surface 11 for receiving the operator's thumb, which surface faces generally upwards.

[0024] It is worth noting that, as a...

Abstract

The invention relates to 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. According to the invention, 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).

Description

technical field [0001] The present invention relates to the field of sampling pipettes, also known as laboratory pipettes or liquid transfer pipettes. They are used for sampling and dispensing liquids in containers or similar. [0002] The invention relates more particularly to manual, single-channel or multi-channel pipettes. In a known manner, manual pipettes are intended to be held in the hand of the operator during liquid sampling and dispensing operations, which are carried out by actuating the movement of a control button by exerting axial pressure on said button to realise. Axial pressure applied to the control button is transmitted via the pipette's control rod to the pipette's piston. Axial displacement of the piston causes air displacement resulting in sampling and dispensing operations. This principle involves so-called air-displacement pipettes, where the sampling cone will be removably mounted on the tip of the pipette. Nevertheless, the invention is also app...
