The invention relates to a manually operated general system and examples of pipettes (in axial and non-axial configurations) having ergonomic properties. The invention relates to a type of manual pipette system comprising a mobile nozzle and a container housing disposable tips, which can be coupled to the casing of the pipette. The system can be configured in two directions, namely: one direction for establishing and altering the configuration between either an axial or non-axial configuration; and another direction for allowing the insertion/ejection of the disposable tips located at the end of the nozzle. The first is achieved using a nozzle having different positions at pre-defined fixed angles ([beta]), whereby for [beta]=0 the system is in an axial configuration and for other values of [beta] it is in a non-axial configuration. For the second, the nozzle can move in rotation and/or translation, so that it is aligned with the disposable tip inside a container, which is subsequentl y inserted into the end of the nozzle. |
