Patent number: 7438861Abstract: A heatable pipette, with a needle has an inner channel defined by an inner wall, arranged to conduct electric current through the inner wall for resistively heating the inner wall. The needle has an outer wall, which is defined between the outer wall and the inner wall and connectable for providing pressure air into the outer channel. By conducting current directly through the inner wall, the inner wall itself operates as resistor. Particularly, if the inner wall is made of an appropriate material, for example of stainless steel, the ohmic resistance of the inner wall is not negligible even if the inner wall is very thin. Therefore, the inner wall can directly be used as resistor for resistance heating of the inner wall even if the needle is manufactured in small dimensions.Type: GrantFiled: May 16, 2007Date of Patent: October 21, 2008Assignee: F.

Publication number: 20070297950Abstract: An equilibration device for equilibrating a comparably economic equilibration of a fluid. A first sealing layer is adjacent to the surface side between the plate and the cover. A second sealing layer is arrangeable adjacent to the cover between the plate and the cover and a tube with an open end, which is inside the well such that the open end of the tube projects above the opening of the well. The use of two sealing layers in the equilibration device allows combining the advantages of a material of the first sealing layer, e.g. high flexibility to seal uneven areas and to compensate the step formed by the tube projecting above the opening of the well, as well as the advantages of the second sealing layer, e.g. inexpensiveness, can come to combined effect when the two sealing layers are arranged appropriately.Type: ApplicationFiled: June 14, 2007Publication date: December 27, 2007Applicant: F.
