Microplate reader with lid lifter for microplates

摘要

Microplate reader has a housing, at least one optical measuring/detection device, a microplate support, a moving unit and an integrated lid holding apparatus. The lid holding apparatus moves the microplate in one respective, at least approximately vertical direction for moving the microplate lid away from the microplate. The lid holding apparatus is arranged inside the housing as a magnetic lifter and comprises a non-array arrangement of at least one permanent magnet, or at least three electro magnets, or at least one switchable permanent magnet. Each microplate lid to be moved away from the microplate comprises magnetizable material with a physical area. A projected area of the at least one permanent magnet, electro magnet, or switchable permanent magnet is smaller than the physical area of the magnetizable material of the microplate lid.

主权项

1. A method for optically measuring in a microplate reader (1) samples in wells (25) of a microplate (8) provided with a microplate lid (7), wherein the microplate reader (1) comprises at least one optical measuring/detection device (2), a housing (3), a microplate support (4) and a moving unit (5), wherein the moving unit (5) is arranged to move the microplate support (4) out of the housing, into the housing (3) and in at least one horizontal direction within the housing (3),
wherein the measuring method comprises the following steps: (a) placing the microplate (8) covered by the microplate lid (7) on the microplate support (4) of the microplate reader (1), the microplate lid comprising magnetizable material; (b) retracting the microplate support (4) and the covered microplate (8) by the moving unit (5) into the housing (3) of the microplate reader (1); (c) moving the microplate lid (7) away from the microplate (8) positioned on the microplate support (4) with a lid holding apparatus (6) integrated in the microplate reader (1) and arranged within the housing (3), and (d) measuring samples in wells (25) of the microplate (8) with the lifted microplate lid (7) by the at least one optical measuring/detection device (2), wherein the lid holding apparatus (6) is arranged as a magnetic lifter (6′) and comprises a non-array arrangement of at least one: (i) permanent magnet (9′), or (ii) electro magnet (10′), or (iii) switchable permanent magnet (11), and wherein each microplate lid (7) to be moved away from the microplate (8) comprises magnetizable material (12) with a physical area; a projected area of the at least one permanent magnet (9′), electro magnet (10′), or switchable permanent magnet (11) being smaller than the physical area of the magnetizable material (12) of the microplate lid (7).
