Method for packing a predetermined liquid substance dose in a straw and device for carrying out said method

摘要

The inventive device is provided with a unit (1) comprising a body (3) which interacts with a pipette tip (24) in a vertical position in order to retain the content of the pipette tip (24) in the unit (1) and comprises a nozzle (2) having a capillary channel (4) insertable into a straw (25) oriented in a transversal position with respect to the body in such a way that, when the body is in a vertical position, said nozzle (2) is in a horizontal position. The inventive method consists in sampling a liquid substance initially contained in a top-open container (45) with the aid of the pipette tip (24) in the vertical position, in transferring the content of pipette tip (24) to the body (3) of the unit (1) prior to filling the straw (25) with the predetermined dose of a liquid substance transferred thereto from the unit (1).

1. Method for packing in a straw (25) a predetermined dose (26′) of a liquid substance initially contained in a receptacle (45) open at the top, including a filling step for causing said predetermined dose (26′) to penetrate into said straw (25), which is lying down, with a filling accessory (1; 1′; 101; 201) nested in said straw, which method comprises, before the filling step:
the step of causing an upright pipette tip (24) to cooperate with said receptacle (45) to take up therefrom at least one dose (26′) of liquid substance; the step of procuring said accessory having a body (3; 103; 203) configured to cooperate with said upright pipette tip (24) and having a spout (2; 102; 202) with a capillary passage (4; 104; 204) configured to be nested in said straw (25), which spout is oriented transversely to said body (3; 103; 203) so that when said body (3; 103; 203) is upright said spout (2; 102; 202) is lying down; and the step of causing said upright pipette tip (24) containing at least said dose (26′), to cooperate with said body (3; 103; 203) so that the content of said pipette tip (26) belongs to said accessory (1; 1′; 101; 201) wherein the following steps are executed automatically: the step of causing said pipette tip (24), in the upright position, to cooperate with said receptacle (45) to take up therefrom said dose (26′) of liquid substance; and the step of causing said pipette tip (24), in the upright position, containing at least said dose (26′) to cooperate with said accessory (1; 1′; 101; 201) so that the content of said pipette tip (26) belongs to that accessory.
