The invention provides a dedicated double-row imbibition head for a micro-plate washer, which comprises an imbibition head main body, two suspension screws, a pipe connector, a plurality of silica gel plugs, a plurality of magnetic rods and a plurality of imbibition needle tubes, wherein the suspension screws are respectively spliced into two symmetric blind holes in front of the imbibition head main body by glue; the pipe connector is spliced into a hole at the center of the top surface of the imbibition head main body by glue; two parallel long through-holes with the distance thereof being 9mm are formed on the left and right lateral surfaces of the imbibition head main body and communicated with the hole on the top surface; the silica gel plugs are respectively spliced into four blocked holes on the left and right lateral surfaces of the imbibition head main body by glue; four blind holes with the distance thereof being 18mm are evenly distributed in a row in the horizontal direction at the center of the bottom surface opposite to the top surface of the imbibition head main body; the magnetic rods are respectively spliced into the blind holes distributed in the row in the horizontal direction by glue; and the imbibition needle tubes are respectively spliced into two rows of holes on two sides of the lower part of the imbibition head main body by glue, the two rows of holes are symmetrically arranged on the bottom surface of the imbibition head body with the interval between the two rows being 9mm, and each row comprises 8 holes with the interval thereof being 9mm.
Description
technical field [0001] The invention relates to a double-row liquid suction head for a microplate washer, in particular to a special double-row liquid suction head for a 96-well microplate plate washer. Background technique [0002] Since the invention of immunoassay by Yallow and Berson in 1959, immunoassay has increasingly become the main analytical tool in the field of clinical chemistry and environmental monitoring. According to whether it is separated or not in operation, it can be divided into homogeneous immunoassay and heterogeneous immunoassay. Homogeneous immunoassays are fast, convenient, and easy to automate, but have not been as successful in practice as the latter. Heterogeneous immunoassays include a step to separate bound and free ligand. Therefore, separation methods have played a key role in the development of heterogeneous immunoassays. In modern heterogeneous immunoassay systems, the secondary or primary antibodies are generally solid-phased, and the s...
