Abstract

The present disclosure is directed to a device for supporting manual pipetting of liquids, to the use of such a pipetting support device, and to a method for pipetting liquid, for example from a number of first vessels to a number of second vessels, wherein a moving unit is movable in relation to a first plate and at least partially covers the first plate during use of the pipetting support device, and at least one edge of the moving unit provides guidance to support a manual pipetting procedure from said first plate to said second plate, or vice versa.

First claim

1 . A pipetting support device comprising:
at least one first plate comprising at least one row of first vessels; at least one second plate comprising at least one row of second vessels; and at least one moving unit holding said second plate; wherein the moving unit is movable in relation to said first plate and at least partially covers said first plate during use of the pipetting support device; and wherein at least one edge of the moving unit provides guidance to support a manual pipetting procedure between said first plate and said second plate.

2 . The pipetting support device according to claim 1 , wherein said second plate is located above said first plate and is movable by means of the moving unit above said first plate.

3 . The pipetting support device according to claim 1 , wherein the moving unit is slidable above said first plate in a direction rectangular to the row of vessels in said first plate.

4 . The pipetting support device according to claim 1 , wherein the at least one edge of the moving unit is a straight edge for indicating one row of vessels of said first plate during pipetting.

5 . The pipetting support device according to claim 1 , wherein the moving unit has the shape of a sledge and comprises skids that are arranged essentially rectangular in regard to the at least one edge of the moving unit.

6 . The pipetting support device according to claim 5 , wherein the distance between said skids is adaptable to the dimensions of said first plate.

7 . The pipetting support device according to claim 1 , wherein said first plate and the moving unit containing said second plate are mutually arranged on a baseplate.

8 . The pipetting support device according to claim 7 , wherein said baseplate fixates said first plate, and wherein the moving unit is movable in relation to the baseplate and said fixed first plate.

9 . The pipetting support device according to claim 6 , wherein said baseplate comprises means against slipping in relation to a base the pipetting support device is placed on.

10 . The pipetting support device according to claim 1 , wherein the moving unit comprises a cover at least partially covering said second plate.

11 . (canceled)

12 . (canceled)

13 . A method for pipetting liquid between a first plate containing a number of first vessels and a second plate containing a number of second vessels, the method comprising the steps of
placing said first plate under a moving unit of a pipetting support device, such as a pipetting support device according to claim 1 , wherein the moving unit is movable in relation to said first plate and at least partially covers said first plate during use of the pipetting support device, and wherein the moving unit comprises at least one edge for guidance to support a manual pipetting procedure, moving the moving unit in relation to said first plate until said at least one edge of the moving unit indicates a first row of vessels in said first plate placing said second plate on or into the moving unit, manually pipetting liquid from said indicated row in the first plate to a row of vessels in said second plate, and moving the moving unit in relation to said first plate until said at least one edge of the moving unit indicates another row of vessels in said first plate.

14 . The method according to claim 13 , further comprising the steps of replacing said second plate by a third plate after the step of moving the moving unit and before pipetting liquid from said next neighboring row of vessels in said first plate,
manually pipetting liquid from said indicated neighboring row in the first plate to a row of vessels in said third plate, repeating all preceding steps until all targeted liquid from said first plate has been pipetted.

15 . The method according to claim 13 , wherein the moving unit comprises a moving unit cover at least partially covering said second plate ( 12 ; 12 ′) and being movable above said second plate ( 12 ; 12 ′), and wherein the moving unit cover comprises at least one edge providing guidance to support a manual pipetting procedure, further comprising the steps of
moving the moving unit cover until said at least one edge indicates a second row ( 121 a ′, 121 b ′, 121 c ′) of vessels in said second plate,
manually pipetting liquid from said indicated row of vessels in the first plate to said indicated row of vessels in said second plate, and
repeating all preceding steps until all targeted liquid from said first plate is pipetted to said second plate.

16 . The pipetting support device according to claim 9 further comprising one or more of the following: (a) the baseplate comprises a loading to increase its weight, and (b) the baseplate comprises a sticking lamination at its underside.
