Method of attaching a pipette tip and an apparatus for such method
First Claim
1. A method for securing an attachment of and identifying a replaceable part which receives a liquid to be pipetted and which is attachable to a pipetting device, comprising the steps of:
- opening an interlocking which attaches the replaceable part with the help of an electronically controlled interlocking mechanism for detaching or receiving the replaceable part;
saving information of opening of the interlocking mechanism to a control electronics of a pipette;
closing the interlocking which attaches the replaceable part with the help of an electronically controlled interlocking mechanism for attaching the replaceable part;
saving information of closing of the interlocking mechanism to the control electronics of the pipette; and
providing dispensing parameters and/or type and/or size of the replaceable part with the help of a keyboard to the control electronics to ensure the attachment of a desired replaceable part and to achieve a pipetting readiness.

Abstract
The object of this invention is a method for attaching a pipette tip and an apparatus for such method. The method comprises the following steps: opening the interlocking which attaches the replaceable part with the help of electronically controlled interlocking mechanism for detaching or receiving the replaceable part; saving the information of the opening of the interlocking mechanism to the control electronics of the pipette; closing the interlocking which attaches the replaceable part with the help of the electronically controlled interlocking mechanism for attaching the replaceable part; saving the information of the closing of the interlocking mechanism to the control electronics of the pipette; providing the dispensing parameters and/or type and/or size of the replaceable part with the help of a keyboard to the control electronics to ensure the attachment of a desired replaceable part and to achieve pipetting readiness. The object of this invention is thus also to present a pipetting apparatus where the setting mechanism of the replaceable part is so arranged that it prevents accidentally performed setting mistakes but does not require using of a special tip.

3. An electronically controlled pipette, which comprises:
-
a body, which comprises an end part, where a detachable replaceable part is receivable; an electronic control means, which control the functioning of the pipette; an executing keyboard; a plunger movable in a longitudinal direction of the body for portioning liquid to be pipetted; an electronically controlled interlocking means, with which the detachable replaceable part is interlockable to its position or detachable; and a means for carrying the status of the interlocking means to the electronic control means;
whereinwith the keyboard, the dispensing parameters and/or type and/or size of the replaceable part can be inputted to the electronic control means to ensure the attachment of a desired replaceable part and to achieve a pipetting readiness. - View Dependent Claims (4, 5)

6. A pipetting system which comprises:
-
a syringe with an attaching part; a syringe plunger; and a suction device, wherein in the suction device comprises; a body, which comprises an end part, where a detachable or replaceable part is receivable; an electronic control means, which control a function of the pipette; an executing keyboard; a plunger movable in a longitudinal direction of the body for portioning liquid to be pipetted; an interlocking means which is movable in crosswise direction of the body, with which the detachable or replaceable part is interlockable to its position or detachable; and a directing means for directing the movement of the interlockable means to a direction that differs from the longitudinal direction, wherein the plunger is continuously movable so that the plunger is turnable to a direction different from the longitudinal direction with directing means which direct the movement of the interlocking means, and with the keyboard the dispensing parameters can be inputted to the electronic control means. - View Dependent Claims (7, 8, 9)
