Embodiment Construction

[0013] The filling head comprises a main body 1 of the filling head, suspension screws 2 and 3, pipe joints 4, silica gel plugs 5, 6, 7 and 8, and filling needles 9 to 24. Among them, the suspension screws 2 and 3 are respectively glued to the two blind holes in front of the main body 1 of the liquid filling head; the pipe joint 4 is glued to the hole on the top surface of the main body of the liquid filling head 1; 5, 6, 7, and 8 are respectively glued to the four holes on the left and right sides of the main body of the liquid filling head 1, and the outlets of the holes are blocked; the liquid filling needle tubes 9 to 24 are respectively glued to the main body of the liquid filling head 1 in two rows of 16 holes on both sides below. The whole liquid adding head is connected with the liquid adding movement mechanical device of the microplate washer (not shown) through suspension screws 2 and 3, and moves with it.

Abstract

The invention discloses a double-row charging head of a microplate strip washer, which comprises a charging head body, hanging screws, pipe joints, silicone plugs, and charging needle-tubes, wherein the hanging screws are respectively adhered to two blind holes on the front surface of the charging head body by adhesives, and the pipe joints are adhered to the holes on the top surface of the charging head body by adhesives; two parallel long through holes with the distance of 9mm are respectively processed on the left and right side surfaces of the charging head body, and communicated with theholes on the top surface; the silicone plugs are respectively adhered to four holes on the left and right side surfaces of the charging head body by adhesives, and the outlets of the four holes are blocked; and the charging needle-tubes are respectively adhered to two rows of holes on the two sides of the lower part of the charging head body by adhesives, wherein the two rows of holes are symmetrically formed at the bottom of the body, the distance between the two rows is 9mm, and each row is provided with eight holes with the distance of 9mm. The double-row charging head of the microplate strip washer of the invention is characterized in that the liquid is fed into a channel from the pipe joints, then flows to the two parallel long through holes, and finally drained out from the chargingneedle-tubes.

Description

technical field [0001] The invention relates to a double-row liquid-filling head of a microplate washer, in particular to a double-row liquid-filling head dedicated to 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...
