Abstract

A method of generating a plurality of pipettes. The method comprises providing a tubular element, cutting the tubular element to form a plurality of two pipettes length components each having a length of about two target pipettes, simultaneously rotating the plurality of two pipettes length components, heating a central portion of each one of the rotated two pipettes length components, stretching each two pipettes length component to extend the respective central portion, and dividing each two pipettes length component at the extended central portion to form the two target pipettes.

Claims (13)

1. A method of generating a plurality of polymer pipettes, comprising:

providing a tubular element;

cutting said tubular element to form a plurality of two pipettes length components each having a length of about two target pipettes;

simultaneously rotating said plurality of two pipettes length components;

heating a central portion of each said rotated two pipettes length component;

stretching each said two pipettes length component to extend respective said central portion; and

dividing each said two pipettes length component at said extended central portion to form said two target pipettes.

2. The method of claim 1 , wherein at least one of said heating, said rotating, said stretching, and said dividing is adjusted to the dimensions of said plurality of two pipettes length components.

3. The method of claim 1 , wherein said rotating is performed in front of a heating element performing said heating.

4. The method of claim 1 , further comprising cooling said plurality of two pipettes length components after said stretching.

5. The method of claim 1 , wherein said dividing is performed using an ultrasonic blade.

6. The method of claim 1 , wherein said rotating is performed during said stretching.

7. The method of claim 1 , further comprising heating left and right ends of each said two pipettes length component, said stretching comprises stretching each said two pipettes length component to extend respective said left and right ends so as to form a mouthpiece shape in each said end.
