Abstract

The invention discloses a continuous sampling device used for experiment. The continuous sampling device used for experiment comprises a sampling device body, a handle and a sampling gun rod are arranged on the sampling device body, a reagent chamber is arranged in the sampling gun rod, a sampling piston enclosed and cooperated with the reagent chamber is arranged at one end of the reagent chamberclose to the handle, an adjusting piston for adjusting the amount of the reagent every time is arranged at one end of the reagent chamber far from the handle, a screw positioned at one end of the reagent chamber far from the handle is arranged on the sampling gun rod, an adjusting screw cooperated with the screw thread is arranged on the adjusting piston, a liquid outlet hole communicated with the reagent chamber are arranged at the center of the adjusting screw and the adjusting piston, a sampling head is connected with the liquid outlet hole, a non return valve I is arranged on the liquid outlet hole, a soleplate used for installing a reagent bottle is arranged on the sampling device body, and a communicating pipe connected with the reagent chamber is arranged in the soleplate, a non return valve II is arranged on the communicating pipe, and a sampling driving mechanism used for driving the sampling piston to move to the adjusting piston as well as a resetting-mechanism used for resetting the sampling piston are arranged on the sampling device body.

Description

technical field [0001] The invention relates to a sampler, in particular to a continuous sampler for experiments. Background technique [0002] Enzyme-linked immunosorbent assay (ELISA) is a technique in which known antigens or antibodies are adsorbed on the surface of a solid-phase carrier, and the enzyme-labeled antigen-antibody reaction is carried out on the solid-phase surface. This technology can be used to detect macromolecular antigens and specific antibodies, etc., and has the advantages of rapidity, sensitivity, simplicity, and easy standardization of carriers. [0003] In ELISA experiments, it is necessary to add samples in the experimental wash plate. In the prior art, the sample adding head is generally used for dropwise addition of samples, and reagents need to be manually added to the sample adding head after each sample addition, which not only complicates the operation, but also reduces the experimental efficiency. Contents of the invention [0004] In vi...
